Q&A

Subject: Programmable VS Digital

From: JW

I am getting hearing aids for the first time. Programmable hearing aids will cost $3000; digital will cost $5600. Is there a $2600 difference in quality? Will I have to replace the aids in a few years (I'm 47 years old)? Will the price on digital aids drop as computers have, or will the technology improve so that upgrading will be important? It is a difficult decision. My loss in both ears is a straight decrease from mild in the lower tones to moderate in the high tones. I can still cope without aids, but it is difficult to understand my students when they answer questions in the classroom. I'd appreciate any advice you can give.

Dear JW,

I think you will see both scenarios unfold...price drop for basic products and increasing capability of upgrade. Quite frankly, I think the price difference at this point truly does reflect improvement. Programmable hearing aids DO allow greater flexibility and (with multiple memories) considerably greater options in difficult listening environments. BUT the digital hearing aids go at the process in significantly different ways. For example, some DSP hearing aids scan for recurring sounds (noise) and reduce those bands allowing for a greater signal-to-noise ratio. Digital hearing aids also do not contend with the heat products of analog hearing aids creating a greater predicted life span of component parts.

Undoubtedly, now that the power consumption of digital hearing aids appears under control, the manufacturers will make more creative use of the processing capability of the chips and we will see continuing improvement in the sound quality delivered. One thing to keep in mind is that, regardless of the sophistication of the technology, the signal must still be carried by a defective auditory mechanism (your ears), so perfection for the listener is still beyond our reach.

While programmable hearing aids (including those with digital signal processors) offer the potential of reprogramming as hearing levels change, I believe that technology will continue to improve the products available. Just as with computers, in 4 to 5 years, whatever you current hearing aid, I believe you will have yet another opportunity to improve you listening capability. My advice is to purchase a hearing aid system, from a dispenser with whom you can communicate freely and whom you trust, that best meets your current listening needs. Be prepared to replace that system when something better comes along.

Enjoy your choice!
