I havce a David Clarke H20-10 headset which I REALLY dont want to part with, but its turningout to be noisy in the trike. Is there a way (other than mic muffs) that I can quieten it down? Maybe adjusting squelch on the intercom? Not very clued up about the intercom systems yet, but if its possible this way, would like to try it out!

Any advice appreciated, otherwise will have to sell
