When we think about archaeology, we usually picture dusty bones and broken pottery. But there's another dimension to our past that we've been missing - one that speaks to us across millennia if we're willing to listen.
The emerging field of archaeoacoustics is revolutionizing how we understand ancient civilizations, and what it's revealing might shake up everything you thought you knew about our ancestors' technological capabilities.
Consider this: In the Peruvian Andes, researchers recently discovered that ancient peoples weren't just building impressive temples - they were creating sophisticated acoustic systems that could transmit sound over a kilometer away. They used massive conch shell horns called pututus, and the architecture of sites like Chavín de Huántar was specifically designed to amplify and channel their sounds.
This wasn't primitive technology. This was acoustic engineering.
But here's where it gets really interesting: These weren't just fancy loudspeakers. The sound systems our ancestors built were deeply integrated into their social, political, and spiritual lives. When those pututu sounds echoed across the valleys, they weren't just sending messages - they were creating experiences that bound communities together and connected people to their landscape in profound ways.
Think about that for a moment. While we're busy being impressed by our bluetooth speakers, our ancestors were turning entire valleys into audio systems and entire buildings into acoustic instruments.
And it's not just the Andes. Across the world, researchers are discovering that ancient peoples had a sophisticated understanding of sound and its effects on human consciousness. In England, the Shrine of St. Werburgh was designed with recesses that created what scientists call a "reverberant halo" - an acoustic effect that made pilgrims' prayers sound otherworldly, enhancing their spiritual experience.
This isn't just clever architecture. It's evidence of a deep understanding of how sound shapes human experience.
Perhaps most fascinating are the discoveries being made at ancient rock art sites. Researchers have found that many of these sites were chosen specifically for their acoustic properties. The places where our ancestors chose to paint weren't random - they were often locations with powerful echo effects that could create immersive, multi-sensory experiences.
What we're discovering is that our ancestors weren't just surviving - they were creating rich, complex environments that engaged all the senses. They understood something that we, in our visually-dominated modern world, have largely forgotten: sound has power. It can communicate, heal, transform, and connect.
This matters because it challenges our assumptions about ancient peoples' capabilities and sophistication. It suggests that they had knowledge and understanding that we're only now beginning to rediscover. And it raises some uncomfortable questions about what other capabilities we might be missing because we're looking at the past through our modern, technologically-biased lens.
But there's something else here, something more immediate and personal. In our modern world, we're surrounded by more sound than ever before - but we've never been less conscious of it. We plug in our earbuds to block out the world, treating sound as either entertainment or noise to be eliminated.
What if we're missing something crucial? What if our ancestors' sophisticated understanding of sound wasn't just about technology, but about a deeper way of being in the world?
The emerging field of experimental psychoarchaeoacoustics (yes, that's a real thing) suggests that ancient acoustic spaces can still affect us profoundly today. When we experience these spaces, our bodies and minds respond in measurable ways. It's as if these ancient soundscapes speak to something deep in our human nature, something that transcends time and culture.
This isn't just academic curiosity. As we face the challenges of our increasingly noisy, disconnected modern world, perhaps we need to start listening to what the past has to tell us. Maybe understanding how our ancestors used sound to create meaning, connection, and transcendence could help us reconstruct our own relationship with sound.
The question isn't just what our ancestors knew about sound - it's what we've forgotten, and what we might gain by remembering.

1. Briefing Document
Executive Summary: This briefing document reviews the emerging field of archaeoacoustics, which investigates the role of sound in past societies through a multidisciplinary approach, drawing on archaeology, acoustics, psychology, and other fields. Key areas of focus include:
The study of sound production and perception within archaeological sites, incorporating both built environments and natural landscapes.
The use of experimental methods to reconstruct past sonic experiences, including the use of ancient instruments and sound sources.
The importance of considering both the objective properties of sound (e.g., frequency, reverberation) and subjective human responses (e.g., emotional, psychological).
The application of psychoacoustics and auralization techniques to better understand how past people experienced sound in specific locations.
The interdisciplinary nature of archaeoacoustics and its potential to enhance our understanding of past rituals, communication, and human-environment interactions.
Introduction to Archaeoacoustics
Definition: Archaeoacoustics is a developing field that explores the significance of sound throughout time and across cultures, utilizing acoustical methods to understand the human experience of sound in the past. It goes beyond simple documentation to place acoustical findings within a human context.
As stated, "Archaeoacoustics is a developing field that offers the acoustical community an opportunity to work across disciplines to explore the significance of sound throughout time and across cultures...However, archaeology is about putting such findings in human context."
Multidisciplinary Approach: It integrates various disciplines including archaeology, acoustics, musicology, psychology, architectural studies, engineering, and even neuroscience. This collaboration is essential for comprehensive understanding.
"Lubman’s approach to archaeoacoustics is exemplary in its melding of humanities perspectives, social science, and experimental and analytical acoustical methods. In his work, nonacoustical background research provides context for acoustical investigations."
Moving Beyond Assumptions: Archaeoacoustics challenges the habitual dismissal of sound in archaeological studies. This is often relegated to musicologists who typically study musical culture from a nonsonic perspective (textual and graphical representations of musical practices or the reconstruction of instruments and tuning systems) rather than as a significant sensory experience.
Key Areas of Investigation
Location-Based Sound Effects: One starting point in archaeoacoustics is evaluating location-based sound effects, particularly in relation to historical accounts, mythological premises, and public and ceremonial architecture.
“A common starting point in archaeoacoustics fieldwork has been the evaluation of location-based sound effects, especially in relation to historical accounts, mythological premises, and public and ceremonial architecture.”
Ancient Sound Production: Researchers investigate sounds made with instruments (natural and artificial), as well as voices. This involves analyzing artifacts and re-creating sound scenarios through experimental archaeology.
This includes studies of "sonorous stones, or artificial, such as bone flutes and drums."
Architectural Acoustics: Archaeoacoustics explores the intentional creation of special acoustics in buildings like pyramids, theaters, and cathedrals.
As mentioned in the text, "studies that examine the intentional creation of special acoustics in the construction of buildings such as pyramids, theaters, or cathedrals"
Landscape Acoustics: Focuses on the natural soundscapes and how acoustics may have influenced the selection of sites, particularly for rock art.
"The emphasis in the study of rock art soundscapes is on acoustics in natural landscape settings."
Sonic Communication: Following the premise of sound as a near-universal means for human communication, it is crucial to establish the plausibility of what can be heard and from where. This depends not only on acoustical science but also information from site archaeology.
Experimental Methods and Techniques
Acoustical Measurements: Includes measuring impulse responses (IR) to determine how sound propagates in a given space.
"Archaeoacoustical measurements made by exciting spatial or instrumental acoustics using an impulse... reveal archaeological acoustical features rather than reconstruct specific sounds."
IR, is also the "acoustic fingerprint of a space, and provides a measurement of sound propagation between an emission point and a receiver device."
Sound Sources: Researchers utilize a variety of sound sources including human voice, handclaps, whistles, percussion, and sine sweeps to characterize the acoustic properties of sites. Specific examples are:
Human voice (male, female, or both simultaneously) uttering the vowel "a."
Handclapping for around 5s.
Whistles of different musical tones (between the ranges of C5/C#5 and G5/G#5).
Binaural and Ambisonic Recording: These techniques capture sound as it is heard by human ears, allowing for detailed analysis of sound direction and reverberation. Ambisonic is more precise in angular readings than binaural techniques.
"Although binaural techniques cover in many cases the experimental needs, the Ambisonics technique produces more precise measurements of angular readings of the direction of arrival of echoes and reverberation than the binaural technique."
Auralization: This process uses computer models and recorded impulse responses to recreate the sonic experience of past environments.
"Auralization is a very powerful technique for evaluating sound and acoustics perception in the laboratory… It allows audible sound files from simulated or measured data to be created and reproduced using loudspeakers or headphones."
Psychoacoustics: The study of the subjective human response to sound, including emotional and psychological effects. Includes subjective evaluations using rating scales and physiological measurements like EDA, HR, EMG, and EEG.
"Beyond the study of the physics of sound and objective acoustic parameters, in psychology, this flourishing field mainly focuses on the participants’ subjective appraisal and their physiological and emotional responses to sound."
Case Studies and Examples
Chavín de Huántar, Peru: This site demonstrates the use of conch shell horns (pututus) for communication and ritual, with unique architectural features like ducts that filter frequencies.
"The center duct revealed that they are near-perfect filters for frequencies in the sounding-tone range of the Chavín pututus."
The study at Chavín included experimenting with the "transmission of the sound of large Strombus pututus, which measure around 96 dB(A) at 1 meter" and was found to be "effective to at least 1 kilometer away from the site"
St. Werburgh Shrine: David Lubman's work illustrates how acoustics in a shrine enhanced the prayer experience, creating a "reverberant halo" and promoting a sense of spiritual intimacy.
"Within the shrine recesses, petitioners would hear their own voices reinforced... The petitioners’ voices are reverberated, creating a mysterious-sounding “reverberant halo,” an effect that might seem like talking to another world."
Rock Art Sites: Investigations into rock art landscapes have shown that acoustics may have been a factor in site selection, connecting the visual and auditory experiences.
"Researchers have examined the connection between acoustics and rock art in relation to the location of rock art in naturally sonorous landscapes, as well as in landscapes where artificially produced sounds can induce relevant acoustic responses."
Inca Governance: Pututus are cited as playing a significant role in Inca governance as communication devices, which was explored via empirical data collection and analysis of site-specific sound transmissions.
General Use of Pututus: Conch shell horns were used as signalling devices, but their sonic and gestural versatility allows for a more nuanced interpretation of their ritual uses and cultural meanings.
"Pututus (conch-shell musical horns) are known in the Andes as annunciatory devices enabling their players to call across long distances. However, the sonic and gestural versatility possible in pututu performance constitutes dynamical evidence for nuanced archaeological interpretations of these multifaceted and ritually associated"
Challenges and Future Directions
Reconstructing Past Sonic Experiences: This remains challenging because historical contexts are often lost, and the material culture may be degraded. It is necessary to combine measurements, modeling and simulations to recover the acoustics of the site.
"An archaeoacoustics study of the Ħal Saflieni Hypogeum in Malta found methodological limitations due to changes made to the site over time that affected the acoustics... In these cases, researchers can try to recover the original acoustics of the site through documentation of the place, computer modeling tools, and simulation approaches"
Subjectivity and Interpretation: Researchers need to acknowledge the subjectivity of human experience and use appropriate methods to capture and analyze these aspects.
"The interpretative aspects of archaeoacoustical reconstruction depend on the way in which sound is produced as well as the choices of source and receiver locations that reenact human perspectives for contextual sound transmission."
Experimental Controls: When studying a space, a control site with similar geographical and morphological features with no rock art should be used to compare and contrast the findings.
Auralization and Reproduction: It is crucial to control the attributes of sound reproduction, including differences between source environment and the recording and playback system. Auralization spaces need to have an actual RT that is low enough to allow simulation of lower values.
Development of Experimental Psychoarchaeoacoustics: The need for a dedicated, experimentally focused discipline for understanding how past humans experienced sound.
"Here, we advocate for the emergence of a new and innovative discipline, experimental psychoarchaeoacoustics."
Incorporating Cognitive Neuroscience: Further research could include utilizing findings from cognitive neuroscience to inform studies, although literature typically discusses sound from a philosophical rather than scientific perspective.
Conclusion:
Archaeoacoustics provides valuable insights into the role of sound in the past, and the incorporation of psychoacoustics and auralization opens the door to better understanding not only what sounds existed at sites, but how people in the past likely experienced them. The field highlights the importance of interdisciplinary research to fully comprehend the human experience in different cultures and time periods. This knowledge can bring us closer to understanding the social, cultural, and spiritual values of ancient societies through a sensory experience that is often overlooked in more traditional archaeological research.

Quiz Answer Key
The primary goal of archaeoacoustics is to investigate how sound influenced the human experience in the past. This includes understanding how sound was used in specific landscapes or sites, why certain places were chosen for their acoustic properties, and how sounds were created and experienced by ancient societies.
Pututus, or conch shell horns, were used at Chavín de Huántar to create echoes in the surrounding valley and were also incorporated into the ritual experiences within the site. They were excavated from the site and continue to be important in the Andes today, making them not just an element of the past but relevant to present practices.
The Lombard effect is a psychoacoustic phenomenon where individuals reduce their voice level when they can hear their voices reinforced. In the shrine recesses, petitioners would hear their own voices amplified and thus be prompted to reduce voice level, which may have made the experience more intimate and contemplative, and simultaneously minimized awareness of the surrounding crowd.
A spatial identifier is a composite acoustical feature set that reveals how the physical characteristics of a space or instrument affect sound propagation. It is generated through measurements made by exciting spatial or instrumental acoustics using an impulse (approximating a Dirac function) or robust methods, such as a sinusoidal sweep.
Archaeoacoustical measurements, such as those taken using an impulse response, reveal general acoustical features of a site or instrument, whereas human-performed acoustical tests, using artifacts or replicas, are more interpretive, aiming to reconstruct specific sounds and their potential impact.
The ducts connecting the Lanzón Gallery to the Circular Plaza at Chavín act as near-perfect filters for the sounding-tone range of the Chavín pututus. This suggests a specific design to privilege certain frequencies from the instruments and enhance the sonic experience for those in the Circular Plaza.
David Lubman is considered an archaeoacoustics pioneer who blends humanities perspectives, social science, and acoustical methods. His research methodology is to explore the acoustics of places of persistent human interest, and his work includes studies at places such as the Maya site Chichén Itzá and religious shrines in Europe.
In natural sound environments, there are no physical clues as to where sounds were performed or listened to. Also, historical heritage may have degraded over time, and it can be hard to place sound emitters and receivers in a way that is similar to past practices.
Auralization is used to create audible sound files from simulated or measured data of soundscapes, allowing researchers to reproduce and study how a real space sounds using loudspeakers or headphones. It often requires combining a dry sound stimulus and the acoustic signature of a space, a measurement known as an impulse response.
Subjective measurements, such as verbal and visual self-reports (e.g., the Mood Adjective Checklist or Affect Grid), are used to ascertain how individuals perceive and evaluate sounds, rating their consciously felt emotional experience. This offers insight into the less objective, yet powerful, ways that people interpret sound.

6. FAQ
What is archaeoacoustics and what does it study?
Archaeoacoustics is an interdisciplinary field that explores the significance of sound in the past, bridging archaeology, acoustics, architecture, engineering, musicology, and neuroscience. It investigates how sound was used in specific landscapes and at archaeological sites, why ancient societies valued locations with particular acoustic properties, and what effects sounds and acoustic environments may have had on human experience and behavior. It looks at how ancient sound was created, transmitted, and perceived in various contexts, using both scientific methods and interpretations based on cultural context.
How are the acoustics of ancient sites studied?
Archaeoacoustics employs a range of techniques to study ancient sites, including both physical measurements and psychoacoustic experiments. Researchers use impulse response measurements (often generated through methods like sine sweeps) to capture the acoustic "fingerprint" of a space. They also conduct experiments with replica instruments, like conch shell horns (pututus), to understand how sounds were produced and transmitted within those environments. Binaural and Ambisonics recording techniques are used to analyze sound propagation, and computer modeling and auralization technologies are employed to simulate and recreate past soundscapes. These investigations allow researchers to explore not only the physical characteristics of sound but also how humans might have perceived those sounds.
What role did conch shell horns (pututus) play at Chavín de Huántar?
At the Chavín de Huántar site in Peru, pututus were found in large numbers. These instruments were not merely signaling devices, but instruments for nuanced musical expression. The unique acoustics of Chavín's architecture, such as the underground galleries and ducts, were found to filter and enhance the pututus' sound. This interplay between the pututus and the architecture is hypothesized to have been part of Chavín ritual practices, potentially contributing to a sense of spiritual experience for participants by creating a more immersive and theatrical acoustic environment. The instruments were also used for ritual communication and their sounds are hypothesized to have been used to position humans in relation to their environment.
What is "auralization" and how is it used in archaeoacoustics?
Auralization is a technique that allows researchers to recreate and experience the sound of a space through audible sound files. This is achieved by capturing the acoustic "signature" (impulse response) of a real or simulated environment and then using a mathematical approach called convolution to imprint that signature onto a dry audio signal. The result is an auralized sound that simulates how the dry signal would have sounded within that space. This process can be used to test and evaluate how various soundscapes may have been experienced by people in the past, and can be used to recreate different spatial contexts, and ultimately contribute to understanding the auditory experience in various environments, both historical and modern.
What is psychoarchaeoacoustics and how does it differ from traditional archaeoacoustics?
Psychoarchaeoacoustics is an emerging field that combines archaeoacoustics with experimental psychology, focusing on the subjective, emotional, and physiological responses to sound in past contexts. It moves beyond the objective measurement of acoustic parameters to explore how ancient soundscapes may have influenced the minds and experiences of people through testing and measuring the subjective perception of space in the lab via auralization and listening tests. While traditional archaeoacoustics may document the physical properties of a site's acoustics, psychoarchaeoacoustics seeks to understand the human experience of sound by examining participants’ subjective responses and neural signatures to sound in ancient spaces.
How are emotional responses to soundscapes measured in psychoarchaeoacoustics?
Psychoarchaeoacoustics uses a variety of methods to measure emotional responses to soundscapes. These methods involve both self-reports and physiological measures. Self-reports may include rating scales for basic emotions, affect, and activation levels, and could include visual scales that may be less culturally biased. Physiological measurements, such as electrodermal activity (EDA), heart rate (HR), facial electromyography (EMG), and electroencephalographic activity (EEG), provide more objective data on emotional responses. The field also utilizes listening tests which involve participants responding to sound stimuli through specific questions. These techniques capture different levels of emotional response – subjective, behavioral, and physiological.
What are some of the challenges in archaeoacoustic and psychoarchaeoacoustic research?
Several challenges exist in these fields. One significant issue is the reconstruction of degraded or incomplete archaeological contexts, which can make it difficult to accurately simulate or analyze past soundscapes. Determining the original use of spaces, and therefore the most relevant sound sources and receiver locations is another challenge. Another challenge lies in accounting for the subjective differences in auditory perception across individuals and cultures. Auralization setups can also introduce artifacts if not done carefully. Finally, the need for interdisciplinary approaches and rigorous methodology, especially in experimental design, can be demanding.
How does the study of archaeoacoustics contribute to our understanding of the past?
Archaeoacoustics offers insights into the sensory experiences of past societies and the role that sound may have played in their social, religious, political, and cultural practices. By examining how sound was produced, transmitted, and perceived, it reveals how people may have interacted with their environment, created meaning, and participated in rituals. This field can provide information about social hierarchies, religious practices, technology, and communication strategies, adding a crucial dimension to archaeology that often focuses predominantly on the visual record. It shows that understanding the past is not only about what people saw and touched but also what they heard and how they experienced it.

12. Post-Episode Fact Check
1. The mention of "Shrine of St. Rueberg" appears to be incorrect or potentially fabricated. While there are many medieval shrines with interesting acoustic properties, this specific shrine is not well-documented in archaeological literature.
2. The term "experimental psychoarchaeoacoustics" as used in the podcast may be misleading. While there are studies combining archaeology, acoustics, and psychological responses, this specific compound term is not a widely recognized scientific field.
3. The podcast's description of "oralization" technology might overstate current capabilities. While acoustic modeling and virtual reconstruction of ancient spaces exists, the technology is not yet able to fully recreate ancient soundscapes with complete accuracy.
Note: The majority of the information presented in the podcast about archaeoacoustics, including the discussions of Chavín de Huántar, the putudas, and the relationship between rock art sites and acoustics, appears to be accurate based on current archaeological research.
