There is evidence that elephants communicate via infrasound, generating rumbling vocalizations as low as 14 HZ that can travel up to 10km. The intensity level of these sounds can reach 103 dB. measured a distance of 5. 0 0m from the source. Determince the intensity level of the infrasound 10 km from the source, assuming the sound energy radiates uniformly in all directions.

The overall length of a piccolo is 32. cm. The resonating air column vibrates as in a pipe that is open at both ends. a. Find the frequency of the lowest note a piccolo can play, assuming the speed of sound in air is 340 m/s. b. opening holes in the side effectively shortens the length of the resonant column. If the highest note a piccolo can sound is 4000 Hz, find the distance between adjacent antinodes for this mode of vibration.

Resonance of sound waves can be produced within an aluminum rod by holding the rod at its midpoint and stroking it with an alcohol- saturated paper towel. In this resonace modee, the middle of the rod is a node while the ends are antinodes: no other nodes or antinodes are present. what is the frequency of the resonance if the rod is 1.00 m long?
