Hi there,
I am currently doing a program, in which, a gaussian white noise is generated and it is to be output as a 99 dB gain for hearing purposes only.
I have currently used this code to generate the noise:
% N = randn(1,20000)*sqrt(P);
% sound(N);
where, P = Noise Power
These codes will present a white noise for a desired 2 seconds and that has been successful so far.
1) My query is on how to set the audio output to a gain of 99dB so that I could hear this noise at 99dB specifically.
2) My other query would be on what value should P be in the code above.
I previously used 50-100 as P values and they sounded the same volume.
It would be much appreciated if someone could aid in this matter.
Thanks
Looking forward to a reply:)

Prasad
