Concept explainers
To find: The sound level that is experienced by the person.
Answer to Problem 11P
The sound level that is experienced by the person will be lesser by 3dB if the captain shut down all except one engine.
Explanation of Solution
Introduction:
There is a reduction of 3dB of sound level correspondence to a saving of intensity.
Therefore, the intensity will be cut in half, if two engines are shut down. Hence, the sound level will be
Conclusion:
Hence, the level of the sound will be drop by the factor of more 3dB and so, the final value is
