The attenuation of low-frequency sound has been a challenging task because the dynamics of dissipative systems are generally governed by the rules of linear response, which dictate the frictional ...

Sound has dimension, and it's sometimes easy to forget just how big sound can be. At 20 Hz we're talking about a 56.5-foot wavelength, calculated using 1130 feet per second as a typical value for the ...

Acoustic frequency filters, which convert electrical signals into miniaturized sound waves, separate the different frequency bands for mobile communications, Wi-Fi, and GPS in smartphones. Physicists ...

Written by Bernard D. Beitman M.D. and Ruslana Remennikova, MS. Since the beginning of human civilization, history has shown a correlation between sound and cognitive, mental, and physical wellness. 1 ...
