Bluetooth is a wireless communication that enables data to be transferred between electronic devices. Hearing aids have the capability of being bluetooth-compatible to improve functionality and convience. This allows a person to stream audio and phone calls without having to put the phone up to your ear. Remote wireless microphones are available as an additional accessory with most hearing aid models. A wireless microphone transmits sound from the micropones location directly to the connected hearing instruments via Bluetooth. This can help make speech clearer when in the presence of background noise. These are ideal for large groups or when talking one on one where extra clairity is needed.
For those who do not want anyone to see their hearing aid, the IIC style is perfect. This was designed to be invisible. This model of hearing aid is the smallest device currently available. Because the model is so small, it takes a very small battery, making the battery life drain quicker. With this style of hearing aid sitting so deep in the ear, it is less likely to pick up on background noise; however, it is prone to wax buildup.
CIC's are custom-designed to fit completely inside the ear canal, making it nearly invisible. By putting the microphone deeper into the ear, the person wearing the device does not have as many problems with background noise. This device offers a cosmetic appeal as they are nearly invisible when worn.
ITC's sit in the lower portion of the outer ear, making them comfortable and easy to use. Because they are slightly larger than the CIC models, they have a longer battery life, and have the ability of additional features such as directional microphones for better understanding in noisy environments.
ITE devices come in two different versions; one that fills the lower part of the outer ear which is called a half shell, or the one that fills most of the outer ear called a full shell. Because of their size, they offer the maximum number of additional controls and features. Both styles use a larger battery and can fit a larger internal receiver with additional power for more severe hearing loss. With the device being larger and more visible than others, there is a chance of more background noise, such as wind.
The RIC style hearing aids have two parts connected with a thin wire. The portion that sits in the ear canal is small. This means the ear canal is not fully blocked. Because the ear canal is not fully blocked, this allows low-frequency sounds to enter the ear natually and the high-frequency sounds are being amplified through the hearing aid sitting behind the ear. RIC models are appropriate for high-frequency mild to moderate hearing loss.
BTE hearing aids also consist of two parts. This model sits behind or on top of the outer ear with tubing that routes sounds down into the ear that is connected by an ear tip or earmold. BTE devices come in colors that can blend with hair or skin tones, chrome colors, or bright colors to suit personal styles. The BTE is the largest and most powerful of all the hearing aids and accomdates almost all types of hearing loss.
Rechargeable hearing aids are one of the most requested features that hearing aid users are asking for. Having hearing aids that are rechargeable allow the users to avoid changing a battery and prevent having to carry extra batteries around. Rechargeable batteries also save users from throwing away hundreds of batteries per year and are more enviornmental friendly.
Some extra benefits of rechargeable hearing aids include:
