Question: What is loudness of sound what factor does it depend on?
Loudness is a subjective measure of sound pressure, often referred to as volume. It is proportional to the sound intensity, which is the physical measure of the sound power. Depending on the type of sound and the environment, loudness also depends on several other factors, including the listener's distance from the source, the frequency (or pitch) of the sound, and the shape of the sound wave.
