How is sound intensity level different from sound intensity itself? a The sound intensity level is a logarithm of the actual sound intensity. b The sound intensity level is a multiplication of the actual sound intensity with the density of medium. c The sound intensity level is an addition of the sound with reference intensity rather than the actual intensity. d The sound intensity level is a level of the sound relative to reference intensity rather than the actual intensity.

QUESTION The power output of a sound system is increased by a factor of 25. By what factor should you adjust your distance from the speakers so the sound intensity is the same? PRACTICE IT Use the worked example above to help you solve this problem. A small source emits sound waves with a power output of 82.9 w. (a) Find the intensity 3.05 m from the source. W/m2 (b) At what distance would the intensity be one-fourth as much...

Miranda is measuring the sound intensity level for a speaker by holding a sound level meter. The intensity of the sound wave at her location is 2.6e-07 W/m2. (a) What is the sound intensity level (SIL) recorded on the meter at Miranda's location? i got the answer of 54.14dB (b) The volume of the speaker is turned down until the intensity of the sound being produced decreases by a factor of 150. What does Miranda's sound level meter read now?...

The decibel scale is a logarithmic scale for measuring the sound intensity level. Because the decibel scale is logarithmic, it changes by an additive constant when the intensity as measured in W/m2 changes by a multiplicative factor. The number of decibels increases by 10 for a factor of 10 increase in intensity. The general formula for the sound intensity level, in decibels, corresponding to intensity I is β=10log(II0)dB, where I0 is a reference intensity. For sound waves, I0 is taken...
