    hey all,
    I'm going to design a device which can communicate in noisy industry environment. What i have thought so far is make a headphone which can suppress the background noise and communicate with other people using WiFi. So I'm going to use dsPIC for this application but i have no idea about dsPIC.
    1. So is it possible to use it ? if it is possible please name a dsPIC for this particular application because i need to study about dsPIC before i start my project.
    2. my second question is i'm using WiFi to communication. Is it practical ?
    Thank you!!

    Are you trying to communicate over acoustic noise, or EMI interference?

    An FRS Radio with noise-cancelling headset would work.

    If you want a DIY for acoustic noise, there are several schematics for noise cancelling microphones on the net. It essentially involves an environment/ambient microphone, and a directional microphone for voice pickup. Subtract the two signals.

    EMI noise is a matter of finding frequency bands that are noise free in the environment, and using digital encoding for transmission.
