fonetika201510-10Currently, there are many models and styles of hearing aids. In recent years, the market development of hearing prosthetics brought enormous diversity and selection in hearing aids. Manufacturers of devices designed to improve hearing are trying to make more and more modern solutions and systems. They strive to achieve the best possible results in speech understanding and sound perception against confounders, which was so far a big problem for hearing aid users.

Today hearing aids available on the market differ in appearance (shape, size, color), construction, properties and electronic systems (the number of microphones, gain level, etc.).

    Classic Behind The Ear (BTE) hearing aids are designed for moderate to severe hearing loss, or in cases where the ear canal is very narrow which excludes the use In The Ear (ITE) or Completely in the Canal (CIC) hearing aids.

    BTE hearing aids are the most common hearing aids used by patients of all ages. BTE are fitted on the ear with the help of custom-made earmold connected with a plastic tube to deliver the sound from the case’s loudspeaker located behind the ear of the patient. From the technology and performance point of view, BTE aids are the most stable and resistant to damage. Besides, BTE is a good choice for people who experience a buildup of earwax. They also have the most features, like volume control, program switch, wireless pairing with a remote control, mobile phone, TV, Bluetooth streamer, FM/Roger systems, and more).

    Receiver In Canal aids with an earpiece in the ear are more discreet on the ear, through the possibility of reducing the size of a case. They can be very elegant and discreet.

    Smaller in size Receiver in Canal aids due to the discretion and elegance are becoming more popular. These devices are indicated for patients whose type of hearing loss or ear canal construction does not allow using In The Ear (ITE) aids. RIC aids are put in small cases placed behind the patient’s ear and connected to the receiver with almost invisible wire. Just like the BTE, RIC aids have multiple features and options of adjustments installed, depending on the user’s needs. RIC aids are very practical solutions for patients who value elegance and discretion.

    The size, and thus, the visibility of hearing aid depends on the type of hearing loss and the shape of the ear canal.

    In The Canal (ITC) aids are recommended for patients with mild to mildly severe hearing loss. The custom made case holding the electronic components is made of hard plastic. ITC are popular among users due to lack of behind-the-ear parts. Canal aids are powered by the 312 or 10 batteries, depending on the size of the ear canal. ITC aids have some options of manual adjustments, but not as advanced as in BTE or RIC aids. Also require more attention and more frequent cleaning and filter replacements.

    Custom made case houses all the electronics of the hearing aid.

    COMPLETELY IN CANAL (CIC) are custom made to measure the ear and placed deep in the ear canal, making them practically invisible. Therefore, the greatest advantage of CIC models is discretion: virtually no one is able to see the hearing aid in the ear. CIC models are fully automatic, without the ability to adjust settings by the patient. They are inserted deeply into the ear, to minimize visibility from the outside. To facilitate removing the CIC aid, there is a thin line installed to pull the camera out of an ear. CIC style is recommended for patients with a fairly wide ear canal, who are focused on aesthetics and almost complete discretion.

    The smallest hearing aid, placed deep in the ear canal, just before the eardrum. It is completely invisible!

    Invisible In Canal (IIC) aids as the name suggests is currently the smallest hearing aid, designed for patients by picking the aesthetics and discretion. This is a device placed in a custom made case basing on an ear mold. This is virtually placed next to eardrum, while it remains completely invisible from the outside. It uses acoustic properties of the ear canal, providing optimum comfort and volume. Due to the size, the IIC aid is powered with the smallest battery number 10 and, like the CIC model, have no adjustable settings.

  • Making IIC aid needs to be preceded by preliminary ear assessment by a hearing care professional.
