Sound from source 3 has a sound intensity level that is 8.3 dB less than sound from source 1. By what factor is the sound intensity from source 3 less intense than the sound intensity from source 1? (Assume the sound intensities for sources 1 and 3 are I1 and I3, respectively.)
Q2. A siren radiates sound uniformly in all directions. A person standing a distance L from the siren regsiters a sound intensity level of 115 dB but a person standing twice that distance registers an intensity of 109 dB. What is the ratio of the intensities at those points. What will the sound intensity level at a distance of 12 L be?
A listener increases his distance from a sound source by a factor of 5.45. Assuming that the source emits sound uniformly in all directions, what is the change in the sound intensity level in dB?
A listener increases his distance from a sound source by a factor of 2.29. Assuming that the source emits sound uniformly in all directions, what is the change in the sound intensity level in dB?
At 3meters from a source that is emitting sound uniformly in all directions the sound level is 53 db. What is the intensity of the sound at 3 meters
1. -/15.4 points My Notes (a) By what factor is one sound more intense than another if the sound has a level 11.0 dB higher than the other? (b) If one sound has a level 32.0 dB less than another, what is the ratio of their intensities? 2. - 17.7 points My Notes If the first sound has a level 19.0 dB lower than the second, what is the ratio of their intensities? first intensity second intensity
5. A sound source has an intensity I1 and when its sound level is measured at a fixed distance the found value is 70 dB. The source increases its intensity to I2 and when its sound level is measured at the same distance the found value is 96 dB. What is the I2 / I1 ratio?
