Microsoft has updated the Project Acoustics software package for Unity and Unreal gaming software platforms.
The Project Acoustics release 2.0 for the Unreal and Unity engines include:
- Dynamic openings – handle changes in geometry at runtime
- Acoustics probe volumes
- Material override – set acoustic material for all meshes within a volume
- Material remap – swap material names for all meshes within a volume
- Probe spacing – change probe spacing within a volume
- Acoustics runtime volumes – update design parameters within a volume
- Pinned probes – place your own probes
- Faster bake times – Acoustic simulations are twice as fast as before
- Various bug fixes and performance improvements
For more info on the new release, read more on the Microsoft tech community blog post.
A company called Syng, have released a new loudspeaker called the Cell Alpha Triphonic Speaker. Company co-founder, Christopher Stringer worked for Apple during 21 years and left in 2017 to create Syng. He was involved directly in developments for the iPhone and iPad, Apple Watch, and the HomePod. Stringer is referenced on more than 1,400 US patents. The first Triphonic sound system was actually patented in 1984 by Emil L. Torick (inventor) on behalf of CBS Broadcasting.

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.

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.
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.
