what sort of doctor do you see if you've recently noticed a problem with your hearing? Lately, like in the past month lately, I'm noticing that I'm having increasing difficulty filtering audio input, which is troubling because I'm usually really comfortable in noisy environments, but just in the past little while I notice I'm having difficulty pulling spoken conversation out of background noise, or really focusing on stuff I want to hear over any sort of extraneous noise, which is something I never used to have an issue with before. I can still hear everything, but something seems to be going loose in the wiring when processing it.
