In Ivan's project SOS filters are implemented using ESP32 assembler, so they are really fast. A quote from him: Well, now you can lower the frequency of ESP32 down to 80MHz (i.e. for battery operation ...

What you need to know about understanding frequency response curves of loudspeakers. Note: Paul Dicomo was a great friend to eCoustics and many of us over the past 2 decades. Sadly, Paul lost a ...

1 In most experiences, sound is part of a larger context. In terms of physics, a sound is composed of a waveform called frequency expressed in Hertz (Hz), a standard international measurement.

Researchers describe an acoustic meta-surface that uses pingpong balls, with small holes punctured in each, as Helmholtz resonators to create inexpensive but effective low-frequency sound insulation.

and it must be one of four frequency components with the largest sound level. · There must be at least four frequency peaks between 150 Hz and 4,000 Hz. · The sound level of the largest four frequency ...

High frequency hearing loss is a disorder that affects a person’s hearing. People with high frequency hearing loss have trouble hearing high frequency sounds. Exposure to certain types of noise ...
