“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.
Read moreWhat is the difference between low and high-frequency?
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.
Read moreHow do you determine low frequency?
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.

Read moreWhat is considered a high-frequency?
High frequency sound is sound of which the frequency lies between 8 and 20 kHz . High frequency sound with a frequency over 16 kHz can hardly be heard, but it is not completely inaudible. High frequency sound and even ultrasound in the lower frequency zone (up to 24 kHz) can be audible if the sound level is high enough.
