RE:of topic - ACOUSTICS AGAIN

2001-10-09 by DbbBrook@aol.com

Hi ya EVERY BODY.

The equipment has been set up to compare the physical interactions of two 
sound waves at different freq.: Two generators (A+B) are fed to both an 
oscilloscope and a loud speaker via switch box enabling each to be viewed and 
heard either separately or combined.


AMPLIFIER OSCILLOSCOPE             A         B
      [     [ [                       \   /
      [     [ [_____________[    ] wall
      [ [_________________________________[     ]  (suppose to be box)
      [__________________________//
                                                    //
( I tried to above to draw a diagram, to see if it would help any one better 
- I know not very good, but at least I tried) WEEEEE! Don't give up my 
studies for Art drawing HE HE

DOES ANY ONE KNOW HOW TO WORK OUT THE CALCULATIONS FOR:

The period output A as shown on the Oscillator is: 10 ms (milli seconds or 
metres per seconds)?

The period output B as shown on Oscillator is: 0.1ms

I need to calculate the output freq. for each tone generator and the 
resultant waveform of each sound wave at room temp?

0.1 ms I think is 0.010s?  I know anything with nought on left from decimal 
point. Oh I'm getting confused. Does any one know how to do this calculation? 
If so can you explain it to me.

I am awaiting fro books to come through from book stores and libraries, but 
need to do this formula by Wednesday.

Hope u can help any one.

Oh by the way, I hope you have all had a good day and have a good day Tuesday.

Love
