A point sound source is situated in a medium of bulk modulus 1.6times10^(5)N/m^(2). The equation for the wave emitted from it is given by y=a sin(7.5π x-3000πt) .Then velocity wave is v and the displacement amplitude of the waves received by the observer standing at a distance 5m from the source is A.The density of medium is rho . The maximum pressure amplitude tolerable to the observer's ear is 30Pa then qquad rho=1.5kg/m^(3) qquad v=400m/s A =(10^(-4))/(4 pi)m

A point sound source is situated in a medium of dulk modulus 1.6 xx 10^(5) N//m^(2) . An observer standing at a distance 10 m from the source writes down the equeation for the wave as y = A sin (15 pi x - 6000 pi t) . Here y and x are in meter and t is in second. The maximum pressure ampulitude received to the observer's ear is (24 pi) pa, then find. (a) the density of the medium, (b) the displacement ampulitude A of the wave recived by the observer and (c ) the power of the sound source.

IF A is the amplitude of the wave coming from a point source at distance r then

If the amplitude of a wave at a distance r from a point source is A , the amplitude at a distance 2 r will be

The equation of a progressive wave is given by, y = 5 sin pi ((t)/(0.02) - (x)/(20)) m, then the frequency of the wave is

The equation of the progressive wave is y =a sin pi (nt -(x)/(5)) the ratio maximum paritcle velocity to wave velocity is
