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
