Question

A sound source has an intensity level of 90dB. When the same 10 sound sources are sounded together, the intensity level becomes ...​

Answer 1

If the same 10 sound sources are sounded together, then the intensity level becomes 100 dB according to the calculation as follows :-

DISCUSSION :-

Known

TI₁ = 90 dB

n = 10

sound sources Was asked TIn =?

Answer :-  

The level of intensity of a sound source assume IT. Then, there are a number of sources of sound that produce sound together, then the level of intensity of the number of sounds can be searched using  

       $\text{TI}_n = \text{TI}_1 + \text{10 log n}$

So, if there are 10 sound sources the intensity level becomes

$\text{TI}_n = \text{TI}_1 + \text{10 log n}$

$\text{TI}_n = 90 + \text{10 log 10}$

$\text{TI}_n = 90 + 10 \times 1$

$\text{TI}_n = 90 + 10$

$\text{TI}_n = 100 / \text{dB}$

So, the level of intensity of the number of sounds is 100 dB.
