Active noise control circuit

[rohini joshi]

hello frinds,
i m doing project of Actively damping of noise upto 130dB sound level.

But i am not using microcontroller based circuit for that.

Kindly forward any related infromation to the post.


also suggest any ideas related with the same

Sounds like you need to do some home work. Have you searched yahoo?

Do you have a sound pressure of up to 130dB of noise? From a nearby jet airplane? Then move away from the airport.

You forgot to describe the noise. Low frequency hum? High frequency hiss? The roaring sounds from a jet plane? Rock music? Dogs barking?

What do you mean by "Actively damping of noise"?

Sounds like the O.P. is after the Holy Grail of active noise cancellation. (I say that sarcastically because it's kind of like perpetual motion or turning water into wine.)
