Low-profile hearing aids are similar to ITC styles and range from half-shell designs that fill half of the outer ear bowl to full-shell designs that fill almost the entire outer ear. Like ITC styles, low-profile designs are large enough to include directional microphones and manual controls, such as a volume wheel and pushbutton for program switching. The size of a low-profile style makes it desirable for people with dexterity issues because it is easier to handle than smaller sizes. The.

Hearing aids are sound amplifying devices designed to help people who have a hearing impairment. Most hearing aids share several similar electronic components, such as a microphone that picks up sound; an amplifier circuit that makes the sound louder; a miniature speaker (receiver) that sends amplified sound into the ear canal; and batteries that power the electronic components. Some hearing aids also have molds or headphones to direct the flow of sound into the ear and improve sound quality. Hearing aid selection is based on the type and severity of hearing loss, hearing needs and lifestyle.
Analog hearing aids make continuous sound waves louder. These hearing aids essentially amplify all sounds (e.g. Some analog hearing aids are programmable. They have a microchip that allows the device to have programmed settings for different listening environments, such as in a quiet place, such as in a library, or in a noisy place such as in a restaurant, or in a large area such as a football field.
Programmable analog hearing aids can store multiple programs for different environments. As the listening environment changes, you can change the settings of the hearing aid by pressing a button on the hearing aid. Analog hearing aids are becoming less common. Digital hearing aids have all the features of analog programmable hearing aids, but they convert sound waves into digital signals and produce an exact duplication of sound.
Computer chips in digital hearing aids analyze speech and other ambient sounds. Digital hearing aids allow for more complex sound processing during the amplification process, which can improve their performance in certain situations (e.g. background noise and reduced whistling). They also have greater flexibility in programming the hearing aids so that the sound they transmit is adapted to the needs of a specific pattern of hearing loss.
Digital hearing aids also provide multiple program memories. Currently, most people seeking hearing aid are offered the option of choosing only digital technology. More complicated features may allow hearing aids to better adapt to your particular pattern of hearing loss. They can improve their performance in specific listening situations; however, these sophisticated electronic components can also significantly increase the cost of the hearing aid.
Analog hearing aids convert sound waves into electrical signals and then make them stronger. They are usually less expensive and have simple volume controls. Behind-the-ear (BTE) hearing aid may help people with mild to profound hearing loss. BTE hearing aids contain all components, a compartment for the battery, microphone and controls, for example, in a plastic case that fits behind the ear.
The case is connected to a disposable plastic earphone or to a custom mold that emits sound through a transparent tube. The canal supports conform to the ear canal and are available in two styles. The in-the-canal hearing aid (ITC) is designed to fit the size and shape of a person's ear canal. A fully in-the-canal (CIC) hearing aid is almost hidden in the ear canal.
Both types are used for mild to moderately severe hearing loss. In-the-Channel (ITC) is a lightweight plastic housing that sits inside the canal. They are known to be comfortable and easy to use. In addition, they are made to fit the size and shape of the ear.
However, because they are small, some people find it more difficult to use them. In-ear (ITE) hearing aids are slightly larger than ITC hearing aids, but they are easy to handle. The parts are contained in a shell that fills the outer part of the ear. According to the American Speech, Language and Hearing Association (ASHA), the best hearing aids for children are behind-the-ear (BTE), as they can adhere to different types of ear molds.
BTE's are also easy to replace, safe for small ears and easy to handle and clean. We manufacture six styles of hearing aids. Learn about each of them to find out what type of hearing aid is right for you. With six styles of hearing aids available (and numerous types of each), knowing which one to choose can seem overwhelming.
That's where a hearing care professional comes into play. They will recommend a style based on important factors such as your level of hearing loss, aesthetic preferences, lifestyle needs, budget and more. A BTE hearing aid houses the hearing components in a housing that rests behind the ear. A clear plastic acoustic tube directs amplified sound into an earpiece or into a custom mold that is placed inside the ear canal.
BTEs are the most common hearing aids in the world, they are usually the largest and are ideal for moderate to severe hearing loss. RIC style hearing aids are instruments in which the receiver or speaker is located inside the ear canal, which is then connected to the main device using a thin electrical cable. Because of this, RICs are usually smaller than BTE. RIC hearing aids are sleek and sleek, usually packed with features, and are great options for mild to moderate hearing loss.
ITE hearing aids are the largest of custom-fit styles. Each ITE is machine-made from an ear mold with all the components that fit into a plastic shell that then fits smoothly inside the outside of the ear. ITEs are one of two custom styles large enough to accommodate manual controls and are used for mild to severe hearing loss. ITC hearing aids are also custom-made based on a mold of your ear.
They are smaller than ITEs, with only a small part of the hearing aid covering in the outer ear. ITC's come in a variety of faceplate covers, may include manual controls for volume and memory, and are a good custom fit option for mild to mildly severe hearing loss. The CIC hearing aids are custom-made to fully fit the ear canal. Only the tip of a small plastic “handle” is seen outside the canal, which is used to insert and remove the instrument.
Small size can pose dexterity challenges. CIC hearing aids are used to help with mild to moderate hearing loss. IIC hearing aids are the smallest, most discreet hearing aids ever made. This custom fit style inserts into the second bend of the ear canal, making it completely invisible* when worn.
A small plastic handle allows you to remove them daily to promote good hearing health. Their deep placement in the ear means IICs cannot be used by everyone, and are only used for mild to moderate hearing loss. This type of hearing aid is suitable for people who experience wax buildup in their ears or who do not like the sound of their voice to be drowned out. Scientists are using the structure of the fly's ear as a model to design miniature directional microphones for hearing aids.
In addition, some people may prefer the open hearing aid because their perception of their voice does not sound “stuffy”. A variant of the BTE is an open-fit hearing aid that allows the ear canal to remain open by fitting fully behind the ear. If you're already wearing headphones and want to update them, the best place to start is with your current device style. An otolaryngologist is a doctor who specializes in disorders of the ear, nose, and throat and will investigate the cause of hearing loss.
The best option depends on many factors, including the severity of a person's hearing loss, his cosmetic preferences and budget. If you have hearing loss in both bass and treble sounds (for example, you struggle to hear loud and rumbling sounds, full of bass), a more occlusive adjustment of the CIC or ITC styles will help process the sound while remaining fairly discreet. Read on to learn about the different types of hearing aids available and how to choose which one is right for you. Price is also a key consideration because hearing aids range from hundreds to several thousand dollars.
The IIC is the smallest hearing aid available and is located deep in the ear canal, making it largely undetectable to others (depending on the size of the ear canal). A telecoil also helps people hear in public facilities that have special sound systems installed, called induction loop systems. Contact the Information Center of the National Institute on Deafness and Other Communication Disorders (NIDCD) if you have questions about organizations that offer financial assistance for hearing aids. Both techniques have the net result of strengthening sound vibrations entering the inner ear so that people with sensorineural hearing loss can detect them.
