The lower the frequency, the fewer the oscillations. High frequencies produce more oscillations . The units of frequency are called hertz (Hz). Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz.

“Mosquitone Detector” is a new sound measurement app that detects high-frequency noises and ultrasonic sounds hard to hear for human ears . It may have been exposed to artificial high-frequency noise while you do not notice. This app can detect and visualize such high-frequency noises.

Low frequency noise (LFN) is generally defined on the Common Octave Bands as 250 hertz (Hz) or less . You might know it better as that chest-rattling thump of the bass from a car driving past with its music cranked. You can’t really make out the song, but you can feel the beat in your chest.
