>know anyone the function of white and pink sounds??
i think that are healty ear these sounds.<
        If I understand your question properly, pink noise is utilized
in home audio to measure sound levels in your listening area and to adjust
your system controls and loudspeaker placement for optimum 2 Channel Stereo
listening or for Home Theater equipment applications and equipment. this can 
be for ProLogic, Dolby Digital (AC-3), DTS, and Ambisonics. Some pre-amps and 
receivers have pink noise generators to accomplish this. For those that do 
not there are many "Set Up and Audio Test Disks" for sale at reasonable 
prices that will do the same thing. An inexpensive Sound Pressure Level Meter 
like the digital Radio Shack model for under $100 can be used to take highly 
accurate readings and "dial in" your system better than most people can do by 
ear alone.
        I hope this is what you were asking about. If not, try again and we 
will find someone to assit you.
