Hearing Technology
Assistive Listening Devices (ALDs) You may have certain communication needs that cannot be solved with the use of hearing devices alone. These situations may involve the use of the telephone, radio, television, and the inability to hear a door chime, telephone ring and alarm clock People with all degrees and types of hearing loss—even people with normal hearing can benefit from assistive listening devices. There are many assistive listening devices available today, from sophisticated systems used in theaters and auditoriums to small personal systems. Hearing Devices What is a hearing device? A hearing aid is a highly sophisticated communication device. There are many different types of hearing devices as there are many forms of hearing loss but they share five basic components. All of them work on amplification and enhance particular hearing range problems. The design can vary but the overall effect is to empower you to the fullest. How a hearing device works:
Hearing devices come in a variety of styles and design from open fittings to custom fittings are available to match lifestyles and personalities. You and your hearing professional will work together to choose the appropriate device for you. Completely-in-the-Canal (CIC) The smallest custom style, CIC instruments fit deeply and entirely within the ear canal. They fit mild to moderate hearing losses and offer high cosmetic appear as they're nearly invisible when worn. In-The-Canal (ITC) ITC instruments sit in the lower portion of the outer ear bowl, making them comfortable and easy to use. Because they’re slightly larger than the CIC models, they have a longer battery life, and can house additional features such as directional microphones for better understanding in noisy environments, and controls such as volume controls. They fit mild and moderate hearing losses. Half Shell (HS)Half Shell models fill half the bowl of the outer ear. Like ITC models, their size enables the addition of features such as directional microphones, volume controls and push buttons to activate special settings for different listening environments. Because of their size, they may be easier than smaller midels to handle for some people and yet are still often disguised by hairstyles or sideburns. This hearing device style looks similar to the ITC hearing device when worn in the ear but is slightly larger. Full Shell or In-The-Ear (ITE) Full shell models sit flush within the outer ear bowl. Their size allows the maximum number of additional controls and features such as directional microphones, which require space on the outer portion of the instrument. They use a larger battery size than the smaller styles and can fit a larger receiver with enough power for even some severe hearing losses. Because of their flexibility, they’re widely recommended for mild to severe hearing loss. Behind-the-Ear StylesBehind-the-Ear (BTE) models sit behind or on top of the outer ear, with tubing that routes sounds down into the ear that connects to an ear tip or earmold to secure them in the ear canal. Mini BTE with slim tube and tipMini BTEs are designed to hide behind the outer ear, and have ultra-thin tubing to discreetly route sound into the ear. The tubing connects to a soft tip that sits in the ear canal but doesn’t occlude it. The result is a natural, open feeling as airflow and sound enter the ear naturally around the tip, while amplified sound enters through the tip. This is known as “open fitting” and is recommended for mild to moderate high frequency losses. Receiver in the ear (RITE)RITE models, also known as RIC (receiver-in-canal) models, are mini BTEs that have the speaker of the instrument incorporated in the ear tip, instead of in the main body of the instrument. RITE instruments fit mild to severe hearing losses. This hearing device style looks similar to the Mini BTE when worn on the ear. BTE with earmoldBTEs with earmolds fit mild through profound hearing losses. They’re longer shape, following the contour behind the outer ear, generally can house more features, controls, and power than custom models. The earmold color and style, as well as the wearer’s hairstyle, determine exactly how they’ll look on each person. |
