Hearing aids are high priced devices that are generally sold by small business people (audiologists) who are to some extent, salespeople. Hearing aids may cost about as much as a used car.Three types of cognitive learning it is good to have some general rules in mind when you are shopping. Generally speaking, a person is not "aidable" if they break the 50-50 rule on their hearing test-- if their PTA is > 50, or their WRS is 35

With wax or infections. Does not require an impression. BTE hearing aids come in many different colors to match your skin, hair, and bright colors for kids.Three types of cognitive learning they may be connected to external sound sources such as assistive listening devices (directional technology, FM systems, CROS/BI-CROSS hearing devices) and telephones and televisions using a t-coil.Three types of cognitive learning

The PAC/BTE type hearing aids are particularly simple -- very little fitting is needed -- no ear mold, and can practically be used "off the shelf".Three types of cognitive learning of course, they should be "equalized" for the hearing deficit that the patient has. This "equalization" process requires someone to have equipment that "talks" to the digital hearing aid.Three types of cognitive learning some models of BTE now can be adjusted through ones cell phone. This seems to us like a very good idea.

• BAHA -- bone-anchored hearing aid. While it can be used like a conventional hearing aid, usually it is used in people who have good hearing on one side and no hearing on the other -- thus it is a surgically implanted version of the CROS aid.Three types of cognitive learning most people with unilateral hearing loss are enthusiastic about BAHA aids because it works very well and it is unobtrusive. It requires "very good" hearing on the opposite side.Three types of cognitive learning it eliminates the head shadow effect, occlusion effect, and feedback.

BAHA (bone anchored hearing aid). This type of hearing aid works well in persons with severe unilateral hearing loss.Three types of cognitive learning the image to the left, from prosper hospital, shows how a button is inserted into the bone of the skull above the ear. The middle image is from island hearing.Three types of cognitive learning the device is attached to the button within the skull. It is very unobtrusive (once the hair is put back into place).

Hearing aids are very expensive and many people choose not to use them because they can't afford them.Three types of cognitive learning bainbridge et al reported that a 28 to 66% greater prevalence of hearing aid use among more affluent older adults (2014). Although we do not know of any published data on this, the "real" cost of a hearing aid -- which is similar in electronic complexity to an smart phone, is probably roughly a tenth of the "offered price" world wide.Three types of cognitive learning it has been explained to us that hearing aids are special because one buys not only the hearing aid electronics but also bundled maintenance services for several years.Three types of cognitive learning nevertheless, consumers generally have no choice regarding the bundled services. We suspect that allowing competition could result in hearing aids priced at about 10% of current pricing.Three types of cognitive learning

"A reasonable fee" for their services during the trial (which can be substantial). This is a good law that protects the hearing impaired population, many of whom are older and may be vulnerable.Three types of cognitive learning additionally, a "hearing aid clearance" is required, meaning that a physician needs to authorize the dispensing of a hearing aid. This is also a good law, as it prevents people from being fitted with hearing aids who have, for example, brain tumors that need surgery (we have seen this).Three types of cognitive learning

We also think it is a generally good idea to separate the "fox" from the "hen-house" -- in other words, we prefer care models where the entity recommending the hearing aid is not the entity getting paid for the hearing aid.Three types of cognitive learning getting ones hearing aid from costco or a similar mass marketer seems like a fairly safe way to go about it. Situations that have more risk are places where care is "integrated" -- where there is a single entity both evaluating and selling -- i.E.Three types of cognitive learning perhaps a huge health care system that employs both ENT doctors and audiologists that sell hearing aids, or a group of "doctors of audiology" who makes their living by selling hearing aids.Three types of cognitive learning

Other situations where there are high risks of being exploited are situations where there is an "entity" that guarantee's payment -- such as workers compensation or a legal endeavor of some kind, or where a hearing aid is being proposed to a person whose judgement might be impaired -- such as children and some elderly.Three types of cognitive learning if you combine "an entity" paying for the hearing aid, as well as an recipient who can be easily bamboozled, risks are gigantic. We have certainly seen patients with hearing aids fitted on a completely deaf ear, as well as patients who had a minor head injury, have normal hearing, and get hearing aids for no obvious reason.Three types of cognitive learning

• interfacing to other devices -- wifi, radio, cell-phone, computer. Presently many hearing aids use clunky FM or noisy AM t-coil systems rather than contemporary bluetooth or wifi interfaces.Three types of cognitive learning recently though, blue-tooth is available in some high-end aids. Some hearing aids can be configured through smart-phones as well. This is a big advantage.Three types of cognitive learning

We think that, for the most part, people looking for a hearing aid should find a dispensor that is close enough to them that they can easily get their hearing aid serviced, cleaned and checked.Three types of cognitive learning in more rural areas where parking and traffic is less intense, larger distances seem reasonable. You should consider how far the office is from your house or place of work as
