Are Open Ear Hearing Aids the Future? Open ear hearing aids, also known as open-fit, are a non specific type of listening instrument designed to prevent occlusion, one of the most noted and annoying drawbacks to wearing hearing aids. If you hold the palms of your handsagainst your ears, youll experience the booming, unnatural andultimately disruptive sound quality that results from cutting offthe natural flow of air into your ear canal. This is similar to theocclusion many experiences with some listening instruments.When a devices earbud is inserted into your ear, its possible tohear echos, or a tunneling sensation as well as poor sound qualityof your own voice.However, many styles of hearing aids keep the ear canal slightlyopen to allow natural sound and air stream into your canal andavoid the plugged up feel of occlusion. Youll find this featurewidely available in mini-BTE styles, both the RIC, or receiver incanal and the standard units which house the receiver in thedevices case.Cosmetically similar, RIC and standard aids use listening devicetechnology slightly different and its often the preference andneeds of the wearer that make one or the other ideal. Theprimary difference is the use of a tiny receiver in the ear dome ofan RIC unit, rather than in the case. Though in both instances, itis the non-occluding ear piece that makes the devices open-ear.
In fact, it is more than the style of the device that makes it anopen ear hearing aid as they also come in ITE, or in the ear, andother form factors. From the onset, manufacturers design the in-ear portions of the device to keep part of the ear unblocked. Thisis more a function of the shape of the device rather than itselectronic features.For example, the Beltone Touch listening device is a series of ITEdevices shaped to keep the ear open so that the wearers voiceand other sounds come in natural. Relatively new, open-fitdevices have only been around since 2005, though the stylessuperior features are will likely have an industry-wide effect,making open ear hearing aids the de facto design for listeninginsttruments.REFERENCES:http://www.beltone.com/touch.aspxhttp://www.audiologyawareness.com/ha_openear.asphttp://www.asha.org/public/hearing/Different-Styles-of-Hearing-Aids/ For More Information, Call Hearing Aids Orlando FL At: 407-329-4885 Or Visit Us At:
