The howler monkey is the loudest land animal and, under some circumstances, can be heard up to a distance of 8.9 km. assume the acoustic output of a howler to be uniform in all directions and that the threshold of hearing is 1.0 × 10-12 w/m2. a juvenile howler monkey has an coustic output of 63 µw. what is the ratio of the acoustic intensity produced by the juvenile howler to the reference intensity i0, at a distance of 210 m?

Explanation:

P = Acoustic power = 63 µW

r = Distance to the sound source = 210 m

Acoustic power

Threshold intensity =

Ratio

Ratio of the acoustic intensity produced by the juvenile howler to the reference intensity is 113.68

another example of kinetic energy would be,

kinetic energy   >     moving energy
