Answer:
L = 9.91 decibels.
Step-by-step explanation:
The loudness, L is inversely proportional to the square of the distance, d, from the source of the sound.
i.e L
L =
Where k is the constant of proportionality.
When d = 14 feet and L = 85 dB, then;
k = L x
= 85 x
= 16660
k = 16660
L =
Thus, when d = 41 feet, then;
L =
=
= 9.91077
L = 9.91 dB
The loudness is 9.91 decibels.
