Ask Slashdot: Why Are Hearing Aids So Expensive?

solune writes "You can get a tablet these days for a few hundred dollars, and laptops for a few hundred more. Gaming consoles, TVs, and smartphones are all available for under a thousand bucks. Yet, a decent hearing aid for my mom will go upwards of $3000! With ever-shrinking electronic components, better capabilities, and technological advancements, not to mention the rapidly increasing potential user base, I would think quality hearing aids should be coming in a lot cheaper than what we can find. Adding fuel to my fire is that a hearing aid will greatly improve my mom's life — not to mention the lives of millions of others out there. Currently, she suffers from frustration and isolation with having to ask people to 'speak up', and nodding her head to things her kids and grandkids say. We've tried the cheapies, and they're fraught with problems. So, can someone tell me why a hearing aid should be so expensive?"

      Don't worry, this topic deserves about three more submissions before even Slashdot deems it not worthy of a repeat.

      The electronics must be small, they mustn't be very heavy, and the must do something that is computationally expensive (signal isolation in a noisy background), combined with amplification, all in a custom fitting (to your ear) enclosure.

      On the other hand, you have people stating that a mass marketed device which is identical for a run of over 11 million last quarter, with ability to use bigger (lower cost) components, bought in bulk (by the millions) is cheap, so this custom device should be too.

      Basically they are expensive for all the reasons the article poster is ignoring, which reduces the article to "I want one cheaper, waahhhhaaahhh!!!"

    About 2 to 4 of every 1,000 people in the United States are "functionally deaf," though more than half became deaf relatively late in life; fewer than 1 out of every 1,000 people in the United States became deaf before 18 years of age.

    However, if people with a severe hearing impairment are included with those who are deaf, then the number is 4 to 10 times higher. That is, anywhere from 9 to 22 out of every 1,000 people have a severe hearing impairment or are deaf. Again, at least half of these people reported their hearing loss after 64 years of age.

    Finally, if everyone who has any kind of "trouble" with their hearing is included then anywhere from 37 to 140 out of every 1,000 people in the United States have some kind of hearing loss, with a large share being at least 65 years old.

    So even at 140, even ignoring those that cannot be helped by hearing aids and those that cannot afford hearing aids, the truth is that far more than 140 out of 1,000 people buy the products you mentioned. If you move a higher volume, you can price them lower and approach their true cost as your design and overhead costs diminish with numbers. What's more is that "a laptop" will more or less work for me the same as it will work for you. We don't need to mold the laptop to put it in our ears or have it tuned to our needs.

    You also seem to overlook two factors: as electronics get smaller they get more expensive. The second part is that as electronics need to power themselves and get smaller they get even more expensive. And on top of that, my cell phone puts out a lot of heat. The kind of heat I would not want in my ear. So you have to consider that the battery must be small and must not dissipate tons of heat and so therefore the electronics must have a very low power draw. There's not much of a conspiracy to find here, it's an unfortunate reality that prevents someone from storming the market with the new better cheaper hearing aid (pending tech advancements).

    In my family, we look at chipping in to buy our elders hearing aids for presents, I know the nice ones are crazy expensive.

      From Anthony Watts web site supplying some technical info about hearing aids, in his words:
      I wear two ITC/CIC hearing aids with DSP processors built in. Let me tell you a little bit about why they are so expensive. The largest supplier of hearing aids in the USA is Starkey in Minneapolis. I’ve been to the factory, and have experienced the process from start to finish courtesy of the president of the company.
      1. Because hearing aids, especially BTE (behind the ear) and ITC/CIC (completely in the canal) types use a single cell 1.5 volt battery, which can drop as low as 1.3 volts through its useful operational life, the amplifier circuits must be of extremely low power consumption and low voltage. The only chip material that works well for this is germanium, which has a diode junction forward voltage of ~ 0.3V as opposed to the ubiquitous silicon used in consumer electronics which has an ~ 0.7V forward voltage. While germanium was once very common for transistors and some early integrated circuits, it has fallen out of favor in the microelectronics hearing aid world. There are only a handful of sources and companies now that work with germanium, thus the base price is higher due to this scarcity. You can’t just take an off the shelf silicon chip/transistor and put it in these aids. Each one is custom designed in germanium. [Added: power consumption is a big issue also, aids are expected to last a few days on a single battery, if most of the power is being used to overcome the forward diode voltage, it gets lost as heat instead of being applied to amplification use.]
      2. The process of properly fitting a hearing aid is labor intensive. Custom ear molds must be created from latex impressions, and these need to be fitted for comfort. A small variance or burr can mean the difference between a good fitting mold and one that is painful to wear. Additionally, if the mold doesn’t maintain a seal to the inner ear properly the hearing aid will go into oscillatory feedback. Sometimes it takes 2 or 3 attempts to get the fitting right.
      3. On the more expensive aids, labor is involved in doing a spectral hearing loss analysis of the user’s hearing problem, so that the aid doesn’t over-amplify in the wrong frequencies. Just throwing in a simple linear amplifier is destructive to the remaining hearing due to the sound pressure levels involved.
      4. Construction of aids is done by hand by technicians, especially with the popular ITC (in the canal) aids. At the Starkey company, a technician is assigned to create the aid from the ear mold, fit the chips and microphone/receiver and battery compartment, and connect it all with 32 gauge wire and make sure it all fits in the ear mold. This can be a real challenge, because human ear canals aren’t often straight, but bend and change diameter. Imagine a room with a hundred technicians sitting at microscopes assembling these. Each is a custom job. There’s no mass production possible and thus none of the savings from it.
      5. After the aid is created, then there’s the fitting. This process is also hands on. Getting the volume and the audio spectrum match right is a challenge, and audiologists have to have chip programming systems onsite to make such adjustments withing the limits of the aid. Sometimes aids are rejected because the user isn’t comfortable with the fitting, and then the aids go back to the factory for either a new ear mold, new electronics, or both.
      6. There’s a lot of loss in the hearing aid business. Patients don’t often adapt well, especially older people. There may be two or three attempts at fitting before a success or rejection. Patients only pay when the fitting is successful. If it is not, the company eats the effort and the cost of labor and materials. Imagine making PC’s by hand, sending them out to users, and then having them come back to have different cases or motherboards or drives fitted two or three times, and software adjusted until the customer is happy with it.

The components in a hearing aid, by contract, have many miniscule components that are assembled very carefully, by hand, by skilled laborers using loupes and microscopes - more akin to watchmaking than assembly-lines. As such, the assembly labor has resisted outsourcing. Plus, the number of units being assembled by any one company (there are many players in the market) aren't large enough to support well-oiled assembly lines running 24-7. Finally, most hearing aids have some amount of customization to each patient (ear-insert moldings for some models, equalization tuning for others), which further increases cost.

    Others have mentioned the addition cost associated with it being a medical device, which is not insignificant. Lastly, because many hearing aids are paid for by insurance, rather than out-of-pocket, there is less consumer-driven pressure to reduce costs.

Only if you work for a much larger corporation with a VERY nice benefits package, will you find an insurance policy that will cover your hearing aides - or even a portion of it.

    My last pair cost me just shy of $4000. I paid out of pocket since my insurance at the time didn't cover this expense. This is, to date, the second biggest expense I've ever paid, after my car. They were top of the range 11 years ago. I can buy an equivalent model now with the same features from Costco's hearing center now for about $500 each.

    Maybe your mum doesn't need the top of the range aides? Try looking for some with fewer features - say only six channels and two or three programs each (one program for normal environment, one for noisy environment, and one for telephone use if she should so desire). You'll save a ton of money.

    The other reason why hearing aides are usually so expensive is that not everybody has the same ear shape. All in-the-ear aides are made from a custom mold, which does increase the cost.

    Exactly. In fact, remember those supply-and-demand lines from high-school economics. Basically, your revenue at any given price will be given by finding that price on the demand curve, finding the quantity that it gives you, and you multiply them. The visual way to show this is to make a square with the lower-left corner at (0,0) and the upper-right corner at some point on the demand curve. The area in that square is your revenue. But that is far from your maximum possible revenue. It turns out that, in theory, you could make revenue equal to all of the area under the demand curve. That whole triangle! Usually, that ends up being about 100% increase in revenue.

    The way you pull this off is you have to be able to charge $100 from the people who are willing to pay $100 but not $101. And you have to charge $250 from the people who are willing to pay $250 but not $251, etc. In other words, you charge everybody the most that they'll pay. The economics term for this is "price discrimination". Problem is, it's tough to charge different prices from different people. First off, you have the problem of being able to secretly offering different prices to different people. Second, you have the problem of figuring out who's willing to pay more. The internet has made the first problem a non-issue... until people caught Amazon doing it. Remember about 6-7 years ago when someone noticed that, if you went to buy a product on Amazon, and if you were using the same account that you previous used to buy 4 pairs of top-of-the-line Air Jordans, Amazon would quote you a higher price than if your account was used to but Sketchers? Turned out that Amazon was figuring out how "upscale" or how "trailer-park" you tended toward in your purchases, and they could figure out how much more they could squeeze out of you.

    An example which is a little closer to the hearing-aid insurance one is that of airline tickets. Ever noticed how it costs so much more to buy a round-trip ticket which does not stay over a weekend? Who would want to not stay over a weekend? Business people. Who's money are they spending? The company's. Are they going to aggressively price-shop or be willing to stay over the weekend for a better price? Nope. So, they can soak the business travelers for more money.

    This is without regard to the total number of students, but the fact that Tuition increase of 2.6 times matches so closely the Cost Per Credit hour growth of 2.6
    would suggest that the enrollment was not dramatically higher, and this is born out Here where 2002 undergrad enrollment was 17k, and 2011 enrollment was 19k.

    (Total compensation (wages) increased by 1.6 times over that interval. It seems the revenue isn't all flowing into faculty pockets)

    So Without becoming a CPA, and chasing every penny, its clear that the student out of pocket expenses have grown at a rate vastly higher than the University budget as a whole. The vast majority of the expansion in the budget is from tuition.

    The cost of the of a college education has expanded to absorb the available student loan money.
