I brought your post to the attention of my wife, who is an audiologist who also works for a hearing aid manufacturer. Interestingly, while she questions hearing aids as the “next big thing” as compared to some of the other suggestions made in this thread, she did point out that development of hearing aids and hearing aid technologies has been on the front burner for a long time.
Part of it is indeed the harm done to their ears by the Baby Boomers and subsequent generations. She is seeing younger and younger patients all the time, and in most cases, it is due to the loudness of the music they listen to. Without digressing into specifics of the sound pressure that an IPod can put out as compared to, say, a jackhammer or a drag race-car’s engine (which my wife also cited but which I cannot remember right now), she notes that like other technologies, hearing aids are:
– Getting smaller all the time–“completely in [the ear] canal” hearing aids (CICs) have been available for some time. “Behind the ear” ones (BTEs) are still common, though.
– Taking advantage of digital technology. Ten years ago or so, all hearing aids were analog. Now, you cannot find an analog one.
– Programmable (using a PC connected to them) to meet the patient’s specific hearing loss. Highs, lows, in between, or any combination of missing frequencies. Other features include the ability to discriminate against background noise.
Given these advances (among many others) in hearing aid technology, she also notes that “the next big advancement” in them will probably be in convergence technology: that is, your hearing aid will incorporate advances in other fields. For example, your hearing aid might also be your cellphone, and/or your GPS, and/or your IPod, and/or something else. Those are only examples and are a ways off–but such convergences are currently being researched.
If we get to that point with all those capabilities, my wife agrees that we might well be looking at the “next big thing.” But for now, even with hearing aids much improved over the last ten years and continuing to improve, she doesn’t see them as the next big thing as long as all they do is improve the patient’s hearing. She was glad to hear that somebody thought so, though.
