Why does the intensity of sound decrease with distance?
i would have to say because a person/animal can only hear so well and only from a limited distance, therefore a noise further away is harder to hear.
Is it true that sound intensity decreases when the amplitude decreases?
Yes.
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...
Does sound Intensity decrease with the square of distance?
If r is the distance from the sound source the sound intensity drops with (1/r)².
Why does the heart rate decrease as the intensity of exercise also decreases?
As activity level decreases, vasopressor agents that increase heart rate are decreased in a reverse feedback loop of blood pressure homeostasis. Also, the heart rate partly depends on Starling's law,...
