It's not a problem for me to listen to another Treo user while on the phone with them, maybe because I can understand that the Treo has an oversensitive omni directional mic. But, for other people that are constantly and incessantly complaining, i.e. "why is your radio so loud" (when its volume is on 3 out of 30), "who's talking?" (in response to a TV being on in the room), and other clucking and belly-aching.

Is there an app / tweak / hack / hardware mod that will add noise cancelling or desensitize the mic?
