Both hands goes numb after riding for an hour or so

Last few rides, I've had my GoPro mounted to the right side of my handlebars. at certain rpms, you can hear and see the buzz of the bars in the video. That buzz at 70ish mph is enough to lightly numb my hands through my sport gloves in my 30 minute ride. I'll try and post a short clip later.
