A loudspeaker of 30cm diameter vibrates at 2kHz. Given that the pressure generated is 55.1N/m2, determine the displaced amplitude.

Assume air density is 1.59kg/m3 and that the speed of sound is 340m/s.

I have been told that the dimensions given for the loadspeaker is a red herring and not needed in the solution of hte question.

How do you find the displaced amplitude of sound?

2. Relevant equations

3. The attempt at a solution

v = Velocity = 340m/s

f = Frequency = 2kHz = 2000Hz

= Wavelength =

Wavelength = 0.17m (170cm)
