What decreases when the intensity of sound decreases?
The amplitude of the sound waves decreases as the intensity decreases.
Is it true that sound intensity decreases when the amplitude decreases?
Yes.
Which wave property decreases as you get farther away from the source of a sound?
Intensity
Does sound Intensity decrease linearly with distance?
No, it follows the inverse square law. That is, the intensity is inversely proportional to the square of the distance. I2/I1 = (r1/r2)². Intensity decreases with 1/r² from increased distance, while the sound pressure decreases only with 1/r from increased distance.
If beam area decreases the intensity will?
Increase
What decreases when the intensity of sound decreases?
The amplitude of the sound waves decreases as the intensity decreases.
Is it true that sound intensity decreases when the amplitude decreases?
Yes.
When the intensity of a sound decreases what decreases?
That means that it gets weaker.In physics, intensity is defined as power per unit area.

Intensity
What happens when the intensity of a sound decreases?
That means that it gets weaker.In physics, intensity is defined as power per unit area.
Does sound Intensity decrease linearly with distance?
No, it follows the inverse square law. That is, the intensity is inversely proportional to the square of the distance. I2/I1 = (r1/r2)². Intensity decreases with 1/r² from increased distance, while the sound pressure decreases only with 1/r from increased distance.
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.
Why sound loses energy faster in three dimensional?
As compared to what? - In general, if the sound energy spreads out over a larger area, the INTENSITY (power per cross-sectional area) decreases, since total energy must be conserved. (Of course, as some of the sound is absorbed, i.e. converted to other energy forms, the intensity decreases even more.)
Why does moving away from a radio affect the loudness you hear?
because sound waves spread out, intensity decreases with distance from the source.
Is intensity a property of sound?
Sound intensity is a property of sound.
What distance increase is needed to reduce a sound's intensity from an initial 100dB to a final 80dB?
Sound intensity is inversely proportional to the square of the distancefrom the source.-- Increase the distance from the source by 10 times.-- Sound intensity decreases to 1/102 = 1/100 .-- 10 log ( 1/100 ) = -20 dB-- 100 dB - 20 dB = 80 dB
What is the name of sound intensity?
Sound intensity is mesured in decibels !
