Detailed Solution

Concept: The perception of loudness is related to sound pressure level (SPL) , frequency content, and sound duration.
We conclude that the intensity of sound waves is used to calculate sound volume. Decibel(dB) units are used to measure loudness.
Now we consider the following options to determine the loudness of sound in units:
A) Decibel(dB) - this is the correct option because the loudness of sound is measured in decibel(dB) units.
B) Metre(m) - this is incorrect because the metre is the unit of length.
C) Hertz(Hz) - this is the incorrect answer because Hertz is the unit of wave frequency.
D) Metre/second (m/s) - this is the incorrect answer because metre/second is a unit of speed or velocity for any object.
Hence, option 1 is correct.
