Explanation / Answer

Ten buzzers each producing a sound with intensity level of 50 dB

          total intensity = 10 log (10) + 50 = 60 dB.
Two buzzers each producing a sound with intensity level of 57 dB

                         = 10 log (2) + 57 dB = 60 dB.         
One hundred buzzers each producing a sound with intensity level of 40 dB

                         = 10 log (100 ) + 40 dB = 60 dB.
Four buzzers each producing a sound with intensity level of 54 dB              

   = 10 log (4 ) + 54 = 60 dB.
An object emitting a sound with an intensity level of 60 dB.
