PCB Piezotronics has introduced Model 377A13, a prepolarized, 1/2” pressure response type microphone, operating from ICP‚ sensor power, which offers extended frequency capability to 20k Hz (+ 2 dB).

Early frequency loss in the human hearing range (20 Hz to 20,000 Hz) is being better detected thanks to recent developments in artificial intelligence-driven audiology. Given age and environmental ...

Humans can observe what and where something happens around them with their hearing, as long as sound frequencies lie between 20 Hz and 20 000 Hz. Researchers at Aalto University have now developed a ...
