Are you thinking about getting hearing aids? Interested in upgrading the ones you have? While advances in technology have improved the performance and variety of hearing aids, they have also significantly increased their cost. Determining what type or brand of hearing aids to buy can be an overwhelming decision. A hearing aid is an electronic, battery-operated device that amplifies and changes sound to allow for improved communication. Hearing aids receive sound through a microphone, which then converts the sound waves to electrical signals. The amplifier increases the loudness of the signals and then sends the sound to the ear through a speaker. A hearing aid is a device used to help the hard-of-hearing hear sounds better. In the past, a funnel-like amplification cone, called an "ear trumpet" or "ear horn", was used. Now, however, the most common style is a small electronic device that fits into the wearer's ear. The first variety of this device had a rectangular battery pack connected by a thin wire, intended to be held in a pocket. During the mid- to late 20th century, this type of power storage was replaced by a more inconspicuous sort in models in which small, circular batteries were placed in the inserted unit itself. When does the hearing aid warranty expire? Most hearing aids come with a standard 1 year warranty from the manufacturer, although some companies are now offering a full 2 years or more of coverage. Can I get additional coverage after the initial warranty period has ended? Extended warranties that go beyond the first year may be purchased from the manufacturer, your audiologist, a general insurance company, or other companies that have special warranty plans just for hearing aids. Cleaning A Hearing Aid: Wipe the outside of the hearing aid daily with a soft, dry cloth or tissue to remove earwax and body oils. A soft toothbrush may be used to remove stubborn wax. The battery compartment of the hearing aid should be left open at night to insure that the hearing aid is off and also so fresh air can enter the hearing aid and dry it more completely. Hearing aids should be professionally cleaned every 3 to 6 months. Some people tend to develop more earwax then others and they should have their hearing aid cleaned more frequently. It is also important to have the hearing aid wearers ears checked regularly as wax can build up and stop the hearing aid from functioning properly. How Many Different Brands and Types of Hearing Aids Do You Sell? - A dispenser should have several different brands and types of hearing aids to choose from. No single brand or type of aid amplifies sound adequately for every hearing loss. The most common types include: behind-the-ear (BTE), in-the-ear (ITE) and in-the-canal (ITC) hearing aids. Each type allows for different amounts of amplification and adjustability according to its size. For example, because an ITC hearing aid is very small, it is less adjustable and provides only enough amplification for milder hearing losses. Before selecting and purchasing a hearing aid it is important to remember that a hearing aid does not restore your hearing. Hearing aids help make soft sounds louder. According to the Better Hearing Institute, "Modern hearing aids can help 95 percent of persons with hearing loss." There are no "one size fits all" type of hearing aids. Every hearing loss is individual and different. The type and style of hearing aid that will be best for you depends on the nature and level of your hearing loss. Experts say an "intelligent" hearing aid has the potential to help the many people who have hearing problems in both ears. They currently have to use aids that work independently of each other. It means people with hearing problems have to alter the settings on each one when they change environments. Electric hearing aids: These are based on the telephone principle; however, Alexander Graham Bell had nothing to do directly with their development. These appeared first in limited quantities in a table model about 1899, but in wearable and practical instruments beginning only in 1902. Carbon aids were popular through the 1940's. Most of these used a rather large 3-volt or 6-volt battery but did not have enough power to assist those with more than a moderate hearing loss. Consumers report they want hearing aids to provide more benefit in noisy situations, have better sound quality and produce less feedback (Kochkin, 2002). Many of these problems occur due to limitations associated with hearing aid microphones. The microphone for ear-level hearing aids has a relatively small "effective area" within which it works maximally. The effective area is dictated by microphone size and location and can be thought of as the ideal area between the talker and listener. When the hearing aid user is listening to talkers located beyond this effective area, the strength of the signal of interest (the talker's voice) diminishes rapidly as the distance increases, making it difficult to hear.
