    pc speaker sound and chickens...

    Code:
    /* Emits a 7-Hz tone for 10 seconds.
    
         True story: 7 Hz is the resonant
         frequency of a chicken's skull cavity.
         This was determined empirically in
         Australia, where a new factory 
         generating 7-Hz tones was located too
         close to a chicken ranch: When the
         factory started up, all the chickens
         died. 
    
         Your PC may not be able to emit a 7-Hz tone. */
    
    #include <dos.h>
    
    int main(void)
    {
       sound(7);
       delay(10000);
       nosound();
       return 0;
    }
    i got this example from the BC45 help... i've used this before and am familiar with it... however can we adjust the intensity of the signal? thank you...

    [i'd thought it'd make a good funny... that, and i don't wanna wake my folks when i'm pulling an all nighter... y'know, 2 AM in tomorrow... ]

    7 Hz is below the threshold of human hearing, it is a subsonic frequency. Your parents won't hear it, but put it at enough power through a ss woofer and they will feel it!

    yeah i do have a background in the physics of sound so... but the idea was whether or not i could control the amplitude of the signal via a library function, as the range is checked by the sound () function... thanks just the same...
