A point sound source is situated in a medium of bulk modulus 1.6 xx 10^5 N//m^2. An observer standing at a distance 10 m from the source writes down the equation for the wave asy = A sin (15pi x - 6000 pi t). Here y and x are in metres and t is in second. The maximum pressure amplitude tolerable by the observer's ear is 24 pi Pa. Find : the density of the medium.
