Answers
Answer:
Volume is the level at which something is heard or the amount of space a solid, liquid or gas occupies.
With sound, its volume is the loudness of the sound.
With a container, its volume would be its capacity, or how much it can hold.
Volume is often expressed in cubic units determined by the International System of Units.

Measuring the Volume of Sound
The loudness of a sound can be subjective, such as quiet or loud. A more objective measure of sound includes several other factors including:
Sound pressure level (SPL) - The human ear averages the SPL over a period of 600-1000 milliseconds. After about 1 second, the ear created an average and the level of loudness will seem to become stable.
Decibels (dB) - This is the ratio between the power and intensity of the sound. The maximum human sensitivities are between 2 and 4 kHz.
