Answered by Anonymous

Explanation:

Infrasound, sometimes referred to as low-frequency sound, describes sound waves with a frequency below the lower limit of audibility. Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high.

Answered by lavanyapandey12

Answer:Infrasound, in its popular definition as sound below a frequency of 20 Hz, is clearly audible, the hearing threshold having been measured down to 1.5 Hz. Sources of infrasound are in the range from very low-frequency atmospheric fluctuations up into the lower audio frequencies.
