### Sound Waves

goals
Name the sounds of the frequencies given below:
A point sound source is situated in a medium of bulk modulus $1.6\,\times\,10^5\,N/m^2$. An observer standing at a distance 10 m from the source writes down the equation for the wave as $y\,=\,A\,sin\,(15\,\pi\,x\,-\,6000\,\pi\,t)$ Here y and x are in meters and t is in second. The maximum pressure amplitude received to the the observer's ear is $24\,\pi$ Pa, then find :

In a stationary wave :
Two coherent point sound sources $S_{1}$ and $S_{2}$ are placed as shown in the figure. Both are emitting sound of frequency 165 Hz. $S_{1}$ is ahead of $S_{2}$ in phase by $\pi -$radian. (Speed of sound is 330 m/s)
