User: By what amount (in dB) does the intensity level decrease when you increase your distance from a source by a factor of 3?

Note: Distance Costs Decibels The general formula for the number of decibels corresponding to a change in sound intensity to relative to the former intensity is Part A Suppose that a sound has initial intensity measured in decibels. [ This sound now increases in intensity by a factor . What is the new level of sound ? Express your answer in terms of and the factor , using for the log base 10. = Part B Find the change in intensity of a point source of sound that results from moving the listener initially at a distance to a distance from the source . Express the change in intensity in terms of and , using for the logarithm of base 10. = Part C This part will be visible after you complete previous item(s). ]

Note: I'm sorry that that wasn't a good answer. Please hold on while I contact an expert.

Weegy: Sound intensity level decreases inversely as the square of the distance. the intensity of the sound wave decreases with increasing distance from the source. [ So if the distance from the source is doubled (increased by a factor of 2), then the intensity is quartered (decreased by a factor of 4). Similarly, if the distance from the source is quadrupled, then the intensity is decreased by a factor of 16. ]
