Answer 2

We are asked the question what is the frequency of subsonic sound

• We are asked the question what is the frequency of subsonic sound
• The answer here is less than 20  hertz which is the (a) option
• The range of subsonic vibration frequency is less than 20 Hz.
• This cannot be sensed by the human ear. They are also known  as infrasonic vibrations
• The human ear can sense the sound waves of frequency ranging from 20 Hz to 20 kHz.
• The sound waves of frequencies less than the lower limit (i.e.,20 Hz) of the audible range are known as subsonic or infrasonic waves.
• Sound waves with frequencies below the audible range are called infrasonic or subsonic.
