The loudness, L, of a sound (measured in decibels, dB) is inversely proportional to the square of the distance, d, from the source of the sound. A person 15 feet from a jetski, it is 95 decibels loud. How loud is the jetski when a person is 48 feet away?

Jet ski is 29.688 db Loud when a person is 48 feet away.

Step-by-step explanation:

Given:

∝

Distance of a person from Jet ski = 15 feet

Loudness of the sound = 95 decibels

We need to find the Loudness when the distance of person is 48 feet away.

Solution:

∝

so we get;

Where k ⇒ Constant.

first we will find value of k when

Substituting the values we get;

Now we need to find when

Hence Jet ski is 29.688 db Loud when a person is 48 feet away.
