If the distance to a sound source is halved how will the sound intensity level change?
Jleedy
None. The speed of sound in air doesn't depend on its frequency.
(If it did, then a person yelling to you from a distance would sound all garbled, because
each frequency in his voice would reach your ear at a slightly different time.)

∙ 14y agoThe wavelength is reduced to half of its original length, and the ear perceives the pitch of the sound as having risen one octave.

How does light intensity vary with distance form the source?
Light intensity is inversely proportional to the square of the distance: I = k/d2
Why does the intensity of light change with distance?
As light gets farther from the source, the same amount of light spreads out over a larger area.
What happens to the intensity of ionizing radiation when you move away?
The intensity reduces in proportion to the square of your distance from the source.
What is the relationship between the intensity of the radiation given off from a radiation source and distance from the radiation source?
The source doesn't care how far you are from it, or whether you're even there, andthere's no relationship between that and the intensity of the radiation it gives off.However, the intensity of the radiation that you receivefrom it is inversely proportionalto the square of your distance from it ... same math as for gravity.
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 does the intensity of a sound wave change if the distance from the source increases by a factor of 2?
The intensity increases by a factor of 4-APEX
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.

How do the amplitude and the intensity of surface water waves vary with the distance of the source?

By what factor will the sound of a source change the intensity of the waves if the distance is tripled from the sound source?
For sound intensity (acoustic intensity) we use in the free field (direct field) the inverse square law = 1/r². I1 and r1 belong to the close distance and I2 and r2 belong to the far distance.I2 = I1 * (r1/r2)²I2 = I1 * (1/3)² = I1 / 9Three times farther away gives one ninth the sound intensity of the close sound intensity.
How does distance affect intensity of radiation?

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.
How does intensity vary with distance from the source?
It's an inverse-square law - for instance, double the distance, and the intensity will be reduced by a factor 1/4.This assumes that there is nothing absorbing the light (for instance, fog); if there is, the intensity in the above example will of course be even less than 1/4 the original intensity.
