Recreating the Sound of Stonehenge

Bruno Fazenda, Ian Drumm
2013 Acta Acustica united with Acustica  
The use of multiple B-Format impulse responses for various source positions allows embedding of these focussed sources within the reverberant field.  ...  Acoustic measurements were carried out using modern techniques and the response collected in both mono and B-Format at various source-receiver positions within the space.  ...  However, in order to correctly reproduce only the early reflections and reverberation of the space, the direct sound and first reflection must be identified in the impulse responses.  ...

Preserving Human Perspectives in Cultural Heritage Acoustics: Distance Cues and Proxemics in Aural Heritage Fieldwork

Miriam A. Kolar, Doyuen Ko, Sungyoung Kim
2021 Acoustics  
We propose that source–receiver locations in aural heritage measurements should be selected to represent a comprehensive range of proxemics according to site-contextualized spatial-use scenarios, and we  ...  identify and compare acoustical metrics for auditory distance cues from acoustical fieldwork we conducted using this strategy in three contrasting case-study heritage sites.  ...  The funders had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript, or in the decision to publish the results.  ...

3D Multizone Soundfield Reproduction in a Reverberant Environment Using Intensity Matching Method

Huanyu Zuo, Thushara D. Abhayapala, Prasanga N. Samarasinghe
2021 ICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
We address this challenge and propose a multizone reproduction method for 3D soundfield in a reverberant room based on intensity matching.  ...  We develop spatial sound intensity expressions in a reververant room using spherical harmonic decomposition, and build a cost function to optimize sound intensity within multiple spatial zones.  ...  A soundfield in a spherical region is usually characterized by spherical harmonic coefficients of sound pressure, which can be extracted by using higher order microphones such as an EigenMike.  ...

2011 IEEE Transactions on Audio, Speech, and Language Processing  
The extensions of the multizone soundfield reproduction design in reverberant rooms are also included.  ...  Spatial multizone soundfield reproduction over an extended region of open space is a complex and challenging problem in acoustic signal processing.  ...  Note that we need to know the room response coefficients of each loudspeakers to apply this method. Normally, these are measured by microphone recordings (see [15] for detail).  ...
