Reference no: EM13679489

There is evidence that elephants communicate via infrasound, generating rumbling vocalizations as low as 14 Hertz that can travel up to 10 kilometer. The intensity level of these sounds can reach 102 dB, measured a distance of 5.5 meter from the source. Compute the intensity level of the infrasound 10 kilometer from the source, assuming the sound energy radiates uniformly in all directions.

___________dB
