There is a evidence that elephants communicate via infrasound , generating rumbling vocalizations as low as 14 HZ that can travel up to 10 km . The intensity level of these sounds can reach 103 dB , measured a distance of 5.0 m from the source . Determince the intensity level of the infrasound 10 km from the source , assuming the sound energy radiates uniformly in all directions .
