The cabin noise in my 235 is so loud that I can hardly hear ATC in my David Clark headphones. I'm using an ICOM IC-A210 radio which seems to pick up the cabin noise and amplify it. At the moment my cockpit has no sound insulation or upholstery which is part of the problem. Do any LNC2 drivers out there have any words of wisdom for me?

Thanks in advance--
