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

Banging of a hammer and a vehicle's horn are examples of loud sounds whilst gambling of a piano and sound of blowing wind are examples of gentle sounds. Sound: it is a form of electricity produced by way of vibrating our bodies.
The sound waves journey through the ear canal to attain the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to 3 tiny bones in the center ear. those bones expand, or boom, the sound vibrations and send them to the inner ear.
