What determines the volume of a sound?

Answer 1

The volume of a sound is determined by the amplitude of the sound wave. Amplitude refers to the maximum displacement of particles in a medium from their rest position when a sound wave passes through it. The greater the amplitude of the sound wave, the louder the sound will be perceived by our ears. This is why sounds with higher amplitudes are perceived as louder than sounds with lower amplitudes.

Answer 2

The volume of a sound is determined by the intensity of the sound waves, which is directly related to the amplitude of the wave. The greater the amplitude, the louder the sound. Volume is measured in decibels (dB).

Answer 3

Loudness is the subjective personal perception of the ears and brain of a listener. Perceived loudness varies from person to person and cannot be measured.

You can measure the objective sound pressure or sound pressure level SPL but not the subjective loudness.

Answer 4

Usually, people are asking as if there is just "the" amplitude in sound waves in air.

The loudness perception of a sound is determined by the amplitude of the sound waves −

the higher the amplitude, the louder the sound.

Which amplitude of sound (sound amplitude) do you mean?

There are:

amplitude of particle displacement ξ, or displacement amplitude

amplitude of sound pressure p or pressure amplitude

amplitude of sound particle velocity v, or particle velocity amplitude

amplitude of pressure gradient Δ p, or pressure gradient amplitude.

Furthermore, think of the amplitude of the oscillation of a string.

The maximum magnitude of the deflection of a wave is called amplitude.

Answer 5

The source of the sound determines how loud it is. Sound is a pressure wave transmitted through a material medium the energy being released at the point of origin of the sound determines the energy in that pressure wave and the more the energy the louder the sound.

Answer 6

Ampitude, determines the intensity of sound.

Answer 7

The volume of a sound is measured by the sound pressure in pascals or newtons per square meter. The sound pressure level is measured by a sound pressure level meter (SPL meter).

Answer 8

The amplitude of the sound pressure is changed.

Answer 9

If you meant the volume of a sound then it is a decibel meter, which measures in units called decibels and is abbreviated to DB.

Answer 10

Difference in air pressure between the minimum and maximum pressures of the wave.
