OUTPUT FREQ. FOR EACH tone generator and the resultant wavelength of each 
sound at room temp.

A= 10ms
b= 0.1ms

I also have to explain in as much detail what will happen when one of the 
sound wave strikes the wall.

Comment on the speed of the sound wave as it passes through the wall and the 
resultant wavelength in general terms i. e without calculations

Using an SPL meter (?) the sound level in the adjacent rooms is monitored and 
readings taken for the output of each tone generator individually. Predict in 
general terms the relationship between the readings for each freq. giving 
reason for your predictions with reference to acoustic theory.

If the wall were covered in carpet the reflected energy of which freq. (A or 
B) would be reduced most and why?

If there were a hole in the wall show using diagram (AHHHH) how the 
propagation of the wave into the adjacent room would be different for two 
freq.

A microphone is positioned in the test area and it's output fed to the 
oscilloscope.  The freq. of tone generator B is reduced to 110Hz and the 
output from both tone generators combined resulting in 'beating'. Produce a 
rough sketch of the input to the speaker viewed via the oscilloscope, 
describe the resultant aural effect and explain the acoustic theory behind 
this phenomena from first principles.

AHHHHHHHH finished. well can any one give me any advice at all at any of this 
please.

Sorry it was so long.

Love

Debbie
