setting volume level using setvolume function in CMdaaudiotoneutility

[vijayannair]

hi
I wish to know the correspondence of the integer value in SETVOLUME function of CMdaaudiotoneutility class to the decibel (db) value. What is decibel value corresponding to the integer value? If I want to set the volume from -15dB to say 120dB , What integer values I have to give in the setvolume function?

If somebody can give an answer please reply

Are you aware of the acoustic interpretation of dB?

Answering the question: such relation is not defined, you can experiment if you have the necessary measuring equipment, but the results will probably vary between different phone models.
