The Logic Off Topic list

BTW Debbie -- there was a typo I missed in that mail from last week

At the end it read:

>So in the case of two sound waves -- one at 100 Hz and another at 110 Hz -- 
>being added together the cycle of reinforcment and cancellation will have a 
>frequecy of 110 -110 = 10 Hz and will be perceived as and audible beat of 10

Should have been 110 - 100 = 10Hz in the last line. Sorry 'bout that.
