How is the intensity of a sound related to the distance between the source and the receiver?
The intensity of a sound will decrease according to an inverse square law.
How will decreasing the amplitude of the sound waves from a TV affect its intensity?
Amplitude is intensity. It refers to the strength of a sound wave, which the human ear interprets as volume or loudness and if you decrease the amplitude you also decrease its intensity.
What happens to the volume of a sound wave as its amplitude decrease?
You mean by the word 'volume' the intensity of sound wave. Intensity is directly proportional to the square of the amplitude.
What causes sound intensity?
Sound intensity or acoustic intensity (I) is defined as the sound power Pac per unit area A. The usual context is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity. Our eardrums and microphone diaphragms are moved by sound pressure deviations (p), which is a sound field quantity. So we measure the sound with a SPL meter (Sound Pressure Level).
When you turn down the volume what will happen to the sound waves' amplitude?
Intensity of sound is dealt as volume in case of radio sets. Intensity is directly proportional to the square of amplitude. So as volume is turned down, intensity is reduced and so the amplitude is decreased.

How does sound intensity decrease due to density of a substance it passes through?
The speed of sound and density are related as . So the greater the density the speed of sound decreases.
How does the intensity of a sound wave change if the distance from the source is reduced by a factor of 4?
- 6 dB is incorrect. It will decrease by 12 dB.
Is intensity a property of sound?
Sound intensity is a property of sound.
Why does the intensity of a sound decrease as the distance from the source increases?
the waves spread out over a larger areathe waves are absorbed by the medium as they pass through itthe waves are being scattered by irregularities in the medium and don't all proceed forwardetc.
What causes intensity of sound?
Sound intensity or acoustic intensity (I) is defined as the sound power (Pac) per unit area (A). The usual context is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity (measured in W/m²). Our eardrums and microphone diaphragms are moved by sound pressure deviations (p), which is a sound field quantity (measured in pascals Pa). So we measure the sound with a SPL meter (Sound Pressure Level) in decibels.
When you turn down the volume what will happen to the sound waves' amplitude?
Intensity of sound is dealt as volume in case of radio sets. Intensity is directly proportional to the square of amplitude. So as volume is turned down, intensity is reduced and so the amplitude is decreased.
