Questions answered by our expert: Auburn Hearing Centre 2008-11-20 05:18:56 http://koolfm.com/experts/view/all/ 2008 Kool FM There are many styles of hearing aids. The degree of the hearing loss, power and options requirements, manual dexterity abilities, cost factors, and cosmetic concerns are some of the factors that will determine the style the patient will use. The most common styles are: ITE: In-The-Ear units are probably the most comfortable, the least expensive and the easiest to operate. They are also the largest of the custom made styles. ITC: In-The-Canal units are a little more expensive than ITEs. They require good dexterity to control the volume wheels and other controls on the faceplate, and they are smaller than ITEs. MC: Mini-Canals are the size between ITC and CIC. A mini canal is a good choice when you desire the smallest possible hearing aid while still having manual control over the volume wheel and possibly other controls. CIC: Completely-In-the-Canal units are the tiniest hearing aids made. They usually require a removal string due to their small size and the fact that they fit so deeply into the canal. CICs can be difficult to remove without the pull string. CICs do not usually have manual controls attached to them because they are too small. BTE: Behind-The-Ear hearing aids are the largest hearing aids and they are very reliable. BTEs have the most circuit options and they can typically have much more power than any of the custom made in the ear units. BTEs are the units that fit on the back of your ear. They are connected to the ear canal via custom-made plastic tubing. The tubing is part of the earmold. The earmold is custom made from an ear impression to perfectly replicate the size and shape of your ear. http://koolfm.com/experts/view/hearing/auburn-hearing-centre/ http://koolfm.com/experts/view/hearing/auburn-hearing-centre/ 2008-01-23 08:00:00 EDT Basically, if you have two ears with hearing loss that could benefit from hearing aids, you need two hearing aids. It is important to realize there are no normal animals born with only one ear. Simply stated, you have two ears because you need two ears. If we try to amplify sound in only one ear, you cannot expect to do very well. Even the best hearing aid will sound flat or dull when worn in only one ear. Assuming you have two ears that hear about the same, you can do a little experiment at home to better understand how important binaural hearing is: First, gently close just one ear, by simply pressing the little fleshy part in the front of your ear canal (the tragus) into your ear canal -- a little. Do not apply pressure, do not hurt yourself. Just close the ear canal to eliminate sound from entering the ear. The idea is to close that ear for about ten minutes while you watch TV or listen to the radio, or speak with your spouse. Then, after a full ten minutes, remove your finger. What an amazing difference! Localization (knowing where the sound came from) is only possible with two ears, and just about impossible with one ear. Localization is not just a sound quality issue; it may also be a safety issue. Think about how important it is to know where warning and safety sounds (sirens, screams, babies crying, etc) are coming from. Using both ears together also impacts how well you hear in noise because binaural hearing permits you to selectively attend to the desired signal, while squelching or paying less attention to undesired sounds such as background noise. http://koolfm.com/experts/view/hearing/auburn-hearing-centre/ http://koolfm.com/experts/view/hearing/auburn-hearing-centre/ 2008-01-23 08:00:00 EDT Audiology is the science of hearing. An audiologist is a person who has a masters or doctoral degree in audiology. In addition, the audiologist must be licensed or registered by their state or province to practice audiology. Audiologists work in a variety of settings including hospitals, schools, clinics, universities, rehabilitation facilities, cochlear implant centers, speech and hearing centers, private audiology practices, hearing aid dispensing offices, hearing aid manufacturing facilities, medical centers, as well as otolaryngology (ENT physician) offices. Although the vast majority of hearing problems do not require medical or surgical intervention, audiologists are clinically and academically trained to determine those that do need medical referral. As a licensed healthcare provider, the audiologist appropriately refers patients to physicians when the history, the physical presentation, or the results of the audiometric evaluation (AE) indicate the possibility of a medical or surgical problem. Many audiologists also dispense (sell and service) hearing aids and related assistive listening devices for the telephone, TV and special listening situations. http://koolfm.com/experts/view/hearing/auburn-hearing-centre/ http://koolfm.com/experts/view/hearing/auburn-hearing-centre/ 2008-01-23 08:00:00 EDT
