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

Answer:

The value is  $S_a = 72.56 \ dB$

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

            $S_a = S + 10log(18)$

=>         $S_a = 60 + 10log(18)$

=>         $S_a = 72.56 \ dB$
