ore buying a hearing aid, ask your audiologist these questions:
Which features would be most valuable to me?
What constitutes the total price of the hearing aid? Do the benefits of the latest technical advancements outweigh the larger prices?
What is the length of the warranty? Is it possible to extend it? Does the guarantee include upcoming upkeep and repairs?
Is there a test period to try out the hearing aids? (Almost all manufacturers allow for 30 - 60-days trial period in which hearing aids could be brought back for a refund.) What fees will be non-refundable if the hearing aid is returned after the test period?
Can the audiologist provide adjustments and supply servicing and do small repairs? Will lender aids be supplied while repairs are being carried out?
What education does the audiologist give?
Recent forms of hearing aids
Though they work differently than hearing aids fitted externally, implantable hearing aid design serves to increase the transmission of sound vibrations going in the inner ear. Middle ear implants (MEI) are very small devices connected to bones within the middle ear. Rather than magnifying the sound running to the eardrum, the MEI moves the bones themselves. Both of these methods present the equivalent effect of fortifying audio vibrations entering the inner ear so they can be sensed by individuals suffering from nerve deafness.
Bone anchored hearing aids (BAHA) are little devices that are attached to the bones behind the ear. Theses devices transfer audio vibrations direct into the inner ear thru the skull [link widoczny dla zalogowanych], without entering the middle ear. In the main BAHAs are utilized by people that have middle ear problems or hearing loss restricted to one ear. Because an operation is involved to implant either one of these, many hearing specialists consider the benefits do not outweigh the risks.
Research currently underway on hearing aids
Methods are being well thought out by researchers to implement new signal processing strategies to hearing aid design. Signal processing represents the technique in use to alter normal audio waves to amplify sounds to best match the remaining hearing of a someone using a hearing aid. NIDCD funded researchers are also studying how to make hearing aids intensify language signals to help to improve understanding.
In addition, research is checking into the use of computer aided technology in planning and constructing more efficient hearing aids. Investigators continue to look for ways to improve sound transferring to cut back on feedback [link widoczny dla zalogowanych], noise interference and the blockage effect. Additional fields of study centre on the most advantageous methods to select and fit hearing aids to children and other groups whose hearing ability is hard to analyse.
Other anticipated research concentrates upon applying lessons gained from animal cases to try and improve microphones used in hearing aids. NIDCD endorsed scientists are examining the tiny fly Ormia ochracea as they possess an ear structure that allows the fly to determine the origin of sounds easily. This fly possesses an ear structure that has being exploited by scientists as a model for designing lilliputian directional microphones to be implemented in hearing aids. The microphones amplify the audio starting from a particular focal point (generally the direction a person is facing) [link widoczny dla zalogowanych], without the sounds that come in from different directions. Directional microphones have got fantastic promise in making it easier to hear a single conversation, even while besieged by additional voices and noises.
