Subject: Re: Hearing aid owner dissatisfaction From: "Maher, Rob" <rmaher(at)ECE.MONTANA.EDU> Date: Wed, 31 Mar 2004 15:56:16 -0700After seeing that (1) and (2) are related to hearing aid performance, I wonder if there has been any research comparing the true potential available benefit from a high performance signal processing system vs. the market-driven low-power BTE and ITE hearing instruments. Specifically, I have a hunch that better performance might be available using off-the-shelf signal processing elements rather than trying to make everything fit in a thimble and run on 1.2V. The user might then be able to tune the device using training sessions on a PC. Are there laboratory research systems that give users more benefit than what is available on the market? The anecdotes I hear are that users wouldn't mind wearing a Walkman-style headset and belt-mounted processor if the hearing aid actually provided sufficient benefit. The tacit reason users want hidden devices is that they don't really work too well and therefore people are embarrassed to be seen as "impaired". We seem to have overcome the social stigma of eyeglasses (arguably because they work!).
