And a loud or soft sound is identified by its volume, another property of sound. Loud sound has a high volume while soft sound has a low volume. Banging of a hammer and a car's horn are examples of loud sounds while playing of a piano and sound of blowing wind are examples of soft sounds.

Answer 2

Answer:

Loudness of sound is a measure of the sound energy reaching the ear per second.
