Answer:

The noise was reduced by 5.7884 decibels

Explanation:

Using the percentage-decibel table, the 95% decibel level y obtained by interpolation

Percentage Decibel

75 4.86

95 y

100 6.0205

95-75/100-75 = y-4.86/6.0205-4.86

0.8 = y-4.86/1.1605

y-4.86 = 0.8×1.1605

y - 4.86 = 0.9284

y = 4.86+0.9284 = 5.7884 decibels

The Mesolithic is the Old World archaeological period between the Upper Paleolithic and the Neolithic.

Neolithic, also called New Stone Age, final stage of cultural evolution or technological development among prehistoric humans. ...
