(a)
To Calculate: The ratio of highest to lowest intensities at given frequency.
(a)
Answer to Problem 23P
The ratio of highest to lowest intensity at the given frequency is
Explanation of Solution
Given:
Intensity is,
Hearing intensity,
Formula used:
Write the expression for intensity ratio.
Calculation:
The graph for sound level versus frequency is shown below.
The hearing threshold at frequency 100Hz is about
Therefore, the ratio of highest to lowest intensity is given as,
Conclusion:
The ratio is
(b)
To Calculate: The ratio of highest to lowest intensities at given frequency.
(b)
Answer to Problem 23P
The ratio of highest to lowest intensity at the given frequency is
Explanation of Solution
Given:
Intensity is,
Hearing intensity,
Formula used:
Calculation:
The graph for sound level versus frequency is shown below.
The hearing threshold at frequency 5000Hz is about
Therefore, the ratio of highest to lowest intensity is given as,
Conclusion:
The ratio is
