We've recently completed work looking into issues surrounding monitoring and regulation of sound exposure and noise pollution due to outdoor events.
The final report can be accessed here: http://www.aes.org/technical/documents/AESTD1007_1_20_05.pdf
The contributors to the group were:
* Chris Beale (SPLtrack, UK)
* Durand Begault (Charles M. Salter Associates, USA)
* Jon Burton (University of Derby, UK)
* Etienne Corteel (L-Acoustics, France)
* Christian Frick (Rocket Science, Switzerland)
* Jim Griffiths (Vanguardia, UK)
* Adam Hill (University of Derby, UK)
* Marcel Kok (dBcontrol, Netherlands)
* Michael Lawrence (Rational Acoustics, USA)
* Bob McCarthy (Meyer Sound, USA)
* Johannes Mulder (Australian National University, Australia)
* Kees Neervoort (Event Acoustics, Netherlands)
* Elena Shabalina (d&b audiotechnik, Germany)
* Andy Wardle (University of the Highlands & Islands, UK)
The aim of this group was to develop a set of recommendations outlining what needs to be done to address the issue of sound exposure and noise pollution due to outdoor events, with an emphasis on practicality and preservation of a good audience experience.
- Track and recommend standards development for audio networking
- Assemble and organize workshops and other AES convention activities related to audio networking
- Parametric Multi-Channel/Multi-Object Audio Coding
- Coding of 3D Audio Signals
- Low Delay General Audio Coding
- Combined Audio/Speech Coding
- Producing a next generation ("the Web Edition") of the TC's popular educational CD ROM 'Perceptual Audio Coders - What to Listen for' with an extended artifact inventory, enhanced presentation & playback on mobile devices and PCs
- Perceptual evaluation of spatial sound fields
- Multi-dimensional testing and statistics (beyond just basic audio quality)
- Head phone testing
- Speech intelligibility
The Technical Committee of Recording Technology and Practices is in continuous communication with the Producer's and Engineers Wing of the Recording Academy in several areas.
In the area of Master Delivery Recommendations, we support a best practices document that is released to both the AES and the Recording Academy constituencies.
Other current work includes similar documents relating to high resolution audio and immersive music production.
At this moment the TCMA is providing input for workshops, tutorials, etc. to be held in conjunction with society conventions.
- Whitepaper for Frequency Response, Max SPL and Impulsive Distortion measurement
- Automotive loudspeaker measurements
- Common best practice
- 1. Presented at virtual AES conference along with the Loudspeakers and Headphone TC committee and World Heath Organization on safety and concert sound levels
- 2. Organizing a 4th International AES Conference on Hearing and Hearing Loss Prevention. Anticipated Date: Late 2021 to early 2022
- 3. Organizing presentation of World Health Organizations Listen Safe Initiative at Vienna 2020
- To extend knowledge of audio forensic practice and techniques world-wide
- To identify areas requiring additional research
- To bring together professionals and students in the area of audio forensics
- To encourage publication of papers, and to arrange tutorials, conferences and workshops, within the AES
- To support standards committees on forensic audio via fostering of refereed journal publications
Standards work to produce a modern, workable, and accurate procedure to test and calibrate a sound system is underway as SC-04-08.
Cinema Loudness: a study group, led by Eelco Grimm, is working on a report dealing with aspects of this issue.
Subbass Loudness/Measurement: We are continuing to have discussions on this issue, raised at the 57th Conference in Hollywood and discussed in New York.
- Papers sessions
- Identify trends
