What??? Same here from working in a print shop for years. Sucks having to say "what" anytime anybody says anything to me without me being prepared to listen. But it's been so long the wife and kid are at least used to it by now. Or at least blow me off politely since I'm generally only pretending like I'm listening anyway...Naw just too many concerts and machine shop hours. I have industrial deafness. Some tones are just not audible even with a hearing device. I have noticed that sound volume needs to be a bit higher to hear what I can hear lately.
