Cancelled

Noise Cancelation Electronics

I have a piece of street furniture that is going to be deployed all over the world. In order to cool some electrical components I have some loud fans. The effect of the cooling and the fans is noise. Currently about 70db. In certain high end retail I need to be below 40db. I need a PCB with speaker that will invert the audio from the fans reducing the noise. It would work like a noise canceling headphone.
