Question

Problem 3

Answer 1

Given information

Given data:

Near an air conditioner, the noise intensity is dB.

Treating the sound intensity level as a linear scale rather than a logarithmic scale is a common misunderstanding. If the volume of the sound increases by a factor of two,

Step-by-step explanation

Step 1.

In terms of its intensity (I), the loudness level of sound ( ) is defined as:

  

Where  is the intensity of the specified reference level and  is in base-  .

Given that two air conditioner units will be working side by side later, the strength of sound waves generated will be doubled. If the intensity generation was    before, it will now be   .

Since,   

As a result of the rise in dB,
