Concept explainers
(a)
To Calculate: The amount of energy absorbed by the eardrum.
(a)
Answer to Problem 14P
The power output of the sound from speaking a person in normal conversation is
Explanation of Solution
Given:
Intensity is,
Area is,
Hearing intensity,
Formula used:
The sound intensity level is given as,
Here,
Calculation:
The power of the sound wave is equal to the absorbed amount of energy;
So, it is given as,
The power output is given as,
Conclusion:
The energy per second is
