Updated Conferences 2021+

The global situation with COVID continues and has caused many conferences to change to a virtual conference, and dates have been rescheduled. The Events Calendar on Noiseboard has been updated with conference dates.

Changes to Acoustics Conferences in 2020

The shutdown of international travel due to COVID-19 has meant that most international conferences have been cancelled, delayed, or they have transitioned to e-conferences. Here is a list of upcoming conferences related to acoustics and vibrations:

Low Frequency Sirens Get Noticed

An additional siren, which emits low-frequency noise, has been fitted to several Winnipeg Fire Paramedic Service vehicles. The Whelen Howler, is a big speaker inside an enclosure for protection. The operators report that everyone takes notice when the siren is used. The siren emits deep tones that penetrate other vehicles, alerting drivers and pedestrians of the approaching vehicle.

Acoustics in the UK contributes £4.6 billion annually

A report titled “UK Acoustics: Sound Economics”, by the University of Sheffield and Imperial College London, calculate that UK’s acoustics industry has a turn-over of £4.6 billion annually. This is generated by around 750 companies, and over 200 active research grants in over 47 UK universities.

New ISO standard for Soundscapes

The founder of Head Acoustics, Klaus Genuit, said that
“A soup might be delicious or not, but you can’t answer this by knowing the temperature of the soup. It is the same with restaurant soundscapes—you need a lot more information than just noise level.”

At the 177th Acoustical Society of America conference in May 2019 in Louisville, Kentucky, USA, Genuit will present an application of the standard ISO 12913-3, Acoustics — Soundscape, which is still under development.

The new standard requires the use of binaural recording equipment, which Head Acoustics happens to make and sell.
