Question

A low pitch sound is called a____________ sound
A. Pulse
B. Intensity
C. Hoarse
D. Quality

Answer 1

A bass drum, thunder, and a man's deep voice are low- frequency sounds. A high-pitched whistle, squeal, and a child's voice are high-frequency sounds. If a sound is soft, it has a low intensity

Complete step by step solution:
As we know that the human ear can hear $20-20k\,\,Hz$ sounds. Sound signals closer to$20\,Hz$ are considered to be low pitch. Hoarse sound having a vocal tone characterized by weakness of intensity. So, a low pitched sound is called a hoarse sound.

The correct answer is C.

Additional information: Sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain Pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies

Note: The pitch of a sound is our ear's response to the frequency of sound. Whereas loudness depends on the energy of the wave.The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves.
