Question

Sound source A has a deciBel rating of 50 dB. Sound source B is 1000 times more intense. What is the deciBel rating of B

Answer 1

The decibel rating of sound source B is 80 dB. So, the decibel rating of sound source B would be 50 dB + 10 * log10(1000) = 50 dB + 10 * 3 = 50 dB + 30 dB = 80 dB

Step-by-step explanation:

The decibel rating of sound source B can be calculated by taking the decibel rating of sound source A and adding 10 times the logarithm base 10 of the intensity ratio between sound source B and A.

Since sound source B is 1000 times more intense than sound source A, the intensity ratio is 1000.

So, the decibel rating of sound source B would be 50 dB + 10 * log10(1000) = 50 dB + 10 * 3 = 50 dB + 30 dB = 80 dB.
