Question

The sound level at 1.0 m from a certain bullfrog is 60 dB. You are surrounded by 18 such bullfrogs, all 1.0 m from you and all croaking equally loudly at the same time. What sound level are you being exposed to

Answer 1

The value is
`S_a = 72.56 \ dB`

Step-by-step explanation:

From the question we are told that

The sound level is
`S = 60 dB`

The distance from the source is d = 1 m

The number of sources is n = 18

Generally the sound which the person is been exposed to is mathematically represented as

`S_a = S + 10log(18)`

=>
`S_a = 60 + 10log(18)`

=>
`S_a = 72.56 \ dB`
