Question

The sound of one student typing furiously on their History paper which is due at 8:00 am tomorrow morning is 60.0 dB. What will the decibel level be when three sleep deprived students are typing furiously in the same room?

Answer 1

The the decibel level be when three sleep deprived students are typing furiously in the same room is 64.77 dB.

Step-by-step explanation:

Given that,

Decibel level = 60.0 dB

Using formula of decibel level

`\beta= 10 log(I)/(I_(0))`

For one student,

`60.0=10 log(I)/(I_(0))`

For 3 students,

`\beta'=10 log(3I)/(I_(0))`

`\beta'=10log 3+10 log(I)/(I_(0))`

`\beta'=4.77+60.0`

`beta'=64.77\ dB`

Hence, The the decibel level be when three sleep deprived students are typing furiously in the same room is 64.77 dB.
