In the T-coil setting, environmental sounds are removed and sound is picked up from the telephone. All wired telephones must be hearing aid compatible. T-coil (Telephone switch) allows you to switch from the normal microphone setting to a T-coil setting to hear better on the telephone.Feedback suppression helps prevent the hearing aid from producing an uncomfortable squealing sound.Noise Reduction reduces the levels of background noise compared to the sounds you are trying to hear.When the directional microphone is activated, sound in front of you (face-to-face conversation) is amplified to a greater level than sound from behind you. They amplify sound coming from a specific direction to a greater level than sound from other directions. Directional microphone may help you speak in noisy environments.Hearing aids may have features that help in different communication situations, such as, They also have greater flexibility in hearing aid programming so the sound they transmit can be matched to the needs for a specific pattern of hearing loss. The digital hearing aids allow for more complex sound processing during the amplification process which may improve performance in certain situations, such as background noise and whistle reduction. Microchips in digital hearing aids analyze speech and other environmental sounds and store multiple program settings. They have all the features of analog programmable aids, but they convert sound waves into digital signals and produce an exact duplication of sound. As the listening environment changes, the hearing aid settings may be changed by pushing a button on the hearing aid.ĭigital hearing aids are more common. Some analog hearing aids have a microchip to store multiple program settings used in different listening environments, such as in a quiet place (library) or in a noisy place (restaurant or soccer field). They make continuous sound waves louder by amplifying all sounds (speech and noise) in the same way. What is the difference between analog and digital hearing aids?Īnalog hearing aids are less common. However, their small size may make them difficult to handle and adjust. They are the smallest hearing aids available and offer cosmetic and some listening advantages. In-the-canal (ITC) aids and completely-in-the-canal (CIC) aids are tiny cases that fit partly or completely into the ear canal. The ITE aids are larger than the in-the-canal and completely-in-the-canal aids, and may be easier to handle than smaller aids. In-the-ear (ITE) aids have all parts of the hearing aid contained in a shell that fills in the outer part of the ear. These earpieces may reduce the occlusion effect in the ear canal-a plugged up sensation that causes a hearing aid user’s voice to sound louder inside the head-and increase comfort, reduce feedback, and address cosmetic concerns for many users.
Mini BTEs may have a smaller earpiece for insertion, but may also use a traditional earmold. A narrow tube is used to connect the aid to the ear canal. "Mini" BTE, or receiver in canal (RIC) aids are a type of BTE aid that fits behind the ear, but is typically smaller in size. Also, BTE aids are easy to clean and handle, and are relatively sturdy. This style is often chosen for young children because it can accommodate various earmold types, which need to be replaced as a child grows. The case is connected to an earmold or an earpiece by a piece of clear tubing. Behind-the-ear (BTE) aids have most parts contained in a small plastic case that rests behind the ear.
