The loudness, L, of a sound (measured in decibels, dB) is inversely proportional to the square of the distance, d
Klio2033 [76]

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 \alpha \frac{1}{d^{2} }

L = \frac{k}{d^{2} }

Where k is the constant of proportionality.

When d = 14 feet and L = 85 dB, then;

k = L x d^{2}

  = 85 x (14)^{2}

 = 16660

k = 16660

L = \frac{16660}{d^{2} }

Thus, when d = 41 feet, then;

L = \frac{16660}{(41)^{2} }

  = \frac{16660}{1681}

  = 9.91077

L = 9.91 dB

The loudness is 9.91 decibels.
