Abstract. Low frequency noise, the frequency range from about 10 Hz to 200 Hz , has been recognised as a special environmental noise problem, particularly to sensitive people in their homes.

“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.

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’s a low frequency?
Low frequency (LF) is the ITU designation for radio frequencies (RF) in the range of 30–300 kHz . Since its wavelengths range from 10–1 km, respectively, it is also known as the kilometre band or kilometre wave.
