Archaeoacoustics

Last updated

Archaeoacoustics is a sub-field of archaeology and acoustics which studies the relationship between people and sound throughout history. It is an interdisciplinary field with methodological contributions from acoustics, archaeology, and computer simulation, and is broadly related to topics within cultural anthropology such as experimental archaeology and ethnomusicology. Since many cultures have sonic components, applying acoustical methods to the study of archaeological sites and artifacts may reveal new information on the civilizations examined. [1]

Disciplinary methodology

As the study of archaeoacoustics is concerned with a variety of cultural phenonemena, the methodologies depend on the subject of inquiry. The majority of archaeoacoustic studies can be grouped into either a study of artefacts (like musical instruments) or places (buildings or sites).

For archaeological or historical sites that still exist in the present day, measurement methods from the realm of architectural acoustics may be used to characterise the behaviour of the site's acoustic field. [2] When sites have been altered from their original state, a mixed-methodology approach may be used where acoustic measurements are combined with virtual reconstructions and simulations. [3] [4] The output of these simulations may be used to listen to the historical state of the site (via Auralization), to aide in an analysis based in the principles of psychoacoustic and for societal contextualization when historically relevant sources are taken into consideration.

For archaeological objects, acoustic measurements and simulations may be used to investigate the possible acoustic behaviour of artifacts found at a site, as in the case of an acoustic jar. In a similar vein, the relationship between cultural uses of a space and artifacts found within it can be examined experimentally, as with lithophones and ringing rocks.

Notable applications

Natural formations

Iegor Reznikoff and Michel Dauvois studied the prehistoric painted caves of France, and found links between the artworks' positioning and acoustic effects. [5] An AHRC project headed by Rupert Till of Huddersfield University, Chris Scarre of Durham University and Bruno Fazenda of Salford University, studies similar relationships in the prehistoric painted caves in northern Spain. [6]

More recently, archaeologists Margarita Díaz-Andreu, Carlos García Benito and Tommaso Mattioli have undertaken work on rock art landscapes in Italy, France and Spain, paying particular attention to echolocation and augmented audibility of distant sounds that is experienced in some rock art sites. [7] [8] [9] [10] [11]

Steven Waller has also studied the links between rock art and sound.

Structures and buildings

Stonehenge

In 1999, Aaron Watson undertook work on the acoustics of numerous archaeological sites, including that of Stonehenge, and investigated numerous chamber tombs and other stone circles. [12] Rupert Till (Huddersfield) and Bruno Fazenda (Salford) also explored Stonehenge's acoustics. [13] [14] [15] [16] [17] At a 2011 conference, Steven Waller argued that acoustics interference patterns were used to design the blueprint of Stonehenge. [18] [19] Almost a decade later, in a detailed study described in a 2020 journal article of the Journal of Archaeological Science , a team led by Trevor Cox and Bruno Fazenda (Salford) employed an acoustic scale model reconstruction of Stonehenge to examine the acoustics within and around the site at different historical stages of the monument, applying sophisticated architectural acoustics methods and knowledge to studies on prehistoric archaeology, offering novel insight into how speech and musical sounds were altered by the acoustics of Stonehenge. [20] [21]

Chavín de Huantar

Miriam Kolar and colleagues (Stanford) studied various spatial and perceptual attributes of Chavín de Huantar. They identified within the site held the same resonance produced by pututu shells (also used as instruments in the Chavín culture). [22] [19]

Chichen Itza

Scientific research led since 1998 suggests that the Kukulkan pyramid in Chichen Itza mimics the chirping sound of the quetzal bird when humans clap their hands around it. The researchers argue that this phenomenon is not accidental, that the builders of this pyramid felt divinely rewarded by the echoing effect of this structure. Technically, the clapping noise rings out and scatters against the temple's high and narrow limestone steps, producing a chirp-like tone that declines in frequency. [23] [24]

Artifacts

Archaeologist Paul Devereux's work (2001) has looked at ringing rocks, Avebury and various other subjects, that he details in his book Stone Age Soundtracks. [25]

Ian Cross of University of Cambridge has explored lithoacoustics, the use of stones as musical instruments. [26]

Archaeologist Cornelia Kleinitz has studied the sound of a rock gongs in Sudan with Rupert Till and Brenda Baker. [27]

Basement of Necromanteion of Acheron in 2005. Basement of Necromanteion.jpg

Panagiotis Karampatzakis and Vasilios Zafranas investigated the acoustic properties of the Necromanteion of Acheron, [28] Aristoxenus acoustic vases, [29] and the evolution of acoustics in the ancient Greek and Roman odea. [30]

Study groups

The activity of research groups in the field of archaeoacoustics (sometimes called "acoustic heritage") and the related field of music archaeology is determined by the availability of funding, though some groups maintain a long term presence in the field. In the past twenty years, many researchers have undertaken both seminal work in developing methods to identify, conserve, or recreate aspects of historical acoustic environments, [2] [3] [31] as well as case studies at relevant heritage sites. [32] [33]

The Acoustics and Music of British Prehistory Research Network was funded by the Arts and Humanities Research Council and Engineering and Physical Sciences Research Council, led by Rupert Till and Chris Scarre, as well as Professor Jian Kang of Sheffield University's Department of Architecture. It has a list of researchers working in the field, and links to many other relevant sites. An e-mail list has been discussing the subject since 2002 and was set up as a result of the First Pan-American/Iberian Meeting on Acoustics by Victor Reijs. [34]

Based in the US, the OTS Foundation has conducted several international conferences specifically on archaeoacoustics, with a focus on the human experience of sound in ancient ritual and ceremonial spaces. The published papers represent a broader multidisciplinary study and include input from the realms of archaeology, architecture, acoustic engineering, rock art, and psycho-acoustics, as well as reports of field work from Gobekli Tepe and Southern Turkey, Malta, and elsewhere around the world.

The European Music Archeology Project is a multi-million euro project to recreate ancient instruments and their sounds, and also the environments in which they would have been played. [35]

Discredited theories

Prior to the establishment of archaeoacoustics as a formal area of study, the possibility of unintentionally recorded sound contained in ancient artifacts held great interest for some theorists. Phonograph cylinders store sound as engravings in the surface of the cylinder, which can be played back by a phonograph with the proper settings. It was hypothesized that this process could have been accidentally replicated during the creation of a ceramic pot or vase, and that such artifacts could be sonified to recover the sounds contained within the elastic medium.

In 1902, Charles Sanders Peirce expressed this idea when he wrote: "Give science only a hundred more centuries of increase in geometrical progression, and she may be expected to find that the sound waves of Aristotle's voice have somehow recorded themselves." [36] The concept continued to be of interest throughout the second half of the century, with David E. H. Jones discussing the subject in his "Daedalus" column in the 6 February 1969 issue of New Scientist magazine, writing:

[A] trowel, like any flat plate, must vibrate in response to sound: thus, drawn over the wet surface by the singing plasterer, it must emboss a gramophone-type recording of his song in the plaster. Once the surface is dry, it may be played back.

— Jones, 1982 [37]

Jones subsequently received a letter from Richard G. Woodbridge III, claiming to have already been working on the idea and stating that he had sent a paper on the subject to the journal Nature. The paper never appeared in Nature, but the Proceedings of the IEEE printed a letter from Woodbridge entitled "Acoustic Recordings from Antiquity" in its August 1969 edition. In this letter, the author called attention to what he called "Acoustic Archaeology" and described some early experiments in the field. He then described his experiments with making clay pots and oil paintings from which sound could then be replayed, using a conventional record player cartridge connected directly to a set of headphones. He claimed to have extracted the hum of the potter's wheel from the grooves of a pot, and the word "blue" from an analysis of patch of blue colour in a painting. [38]

In 1993, the idea was furthered explored by archeology professor Paul Åström and acoustics professor Mendel Kleiner who reported that they could recover some sounds from pottery, mainly in the upper frequencies. [39]

As discussed in an episode of MythBusters (Episode 62: Killer Cable Snaps, Pottery Record) while some generic acoustic phenomena can be found on pottery, it is unlikely that any discernible sounds (like someone talking) could be recorded on the pots, unless ancient people had the technical knowledge to deliberately put the sounds on the artifacts. [40]

Stonehenge is a prehistoric megalithic structure on Salisbury Plain in Wiltshire, England, two miles (3 km) west of Amesbury. It consists of an outer ring of vertical sarsen standing stones, each around 13 feet (4.0 m) high, seven feet (2.1 m) wide, and weighing around 25 tons, topped by connecting horizontal lintel stones. Inside is a ring of smaller bluestones. Inside these are free-standing trilithons, two bulkier vertical sarsens joined by one lintel. The whole monument, now ruinous, is aligned towards the sunrise on the summer solstice and sunset on the winter solstice. The stones are set within earthworks in the middle of the densest complex of Neolithic and Bronze Age monuments in England, including several hundred tumuli.

French explorers Louis Joliet and Father Jacques Marquette came across it in 1673. The Kaskaskia, a tribe of the Illiniwek people lived in the village. It grew rapidly after a French mission and fur trading post were established there in 1675, to a population of about 6,000 people in about 460 houses. Around 1691 the Kaskaskia and other Illiniwek moved further south, abandoning the site due to pressure from an Iroquois invasion from the northeast.
