In-the-ear (ITE), in-the-canal (ITC), and totally in-the-canal (CIC) hearing aids are three kinds of hearing aids under one title. The shell of the in-the-ear hearing aid is a shell that’s customized to the shape and size of their patient’s ear canal and contains the hearing aid movement. Intense canal hearing aids have been placed deeper in the ear canal compared to ordinary lung hearing aids and so are basically concealed in the ear canal, also referred to as complete in-the-ear hearing aids.

Hearing Aids Pros and Cons

Benefits of deep ear canal hearing aids.

Decreased occlusion result: The occlusion effect is whenever the ear nail cavity or the entrance to the ear canal is occluded by the hearing aid or earmold, and the individual feels that their voice sounds like an echo of sounds dull and unnatural.

The blocked ear effect is largely restricted to low and medium frequency sounds below 2000 Hz. The traditional solution would be to enlarge the earmold venting hole or use an open earmold, but this can easily trigger acoustic feedback and modify the frequency response variety of the hearing aid.

Entirely in-ear hearing aids are located deep inside the ear canal, which can reduce or remove the plugging result. Enhancing noise advantage: The ear has the effect of reflecting and refracting sound waves, which can increase the sound pressure of external sound in the microphone position.

Increased sound pressure at the tympanic membrane: CIC hearing aids are situated deep inside the ear canal, resulting in a drop in the volume of the outer ear canal. As stated by the inverse relationship between pressure and volume, the volume decreases and the stress increases.

Increased headroom (head area ) and decreased stimulation: Headroom is the gap between the true gain of the hearing aid and the maximum gain. Since the CIC is situated in the deep ear canal, the actual gain of the CIC hearing aid could be relatively diminished, leading to a gain in headroom, which can enhance the sound quality of the hearing aid and reduce distortion.

CIC hearing aids are found in the nose that is deep, which averts the standard shape of the ear structure. Therefore, it assists in sound source localization. Small size and concealment: in-the-ear hearing aids are situated about 1/3 of this way out of this external auditory canal and also in the auricular cavity; whereas the complete ear canal is only the size of a small fingernail; the volume of the artery type lies between.

Due to the small dimensions, there’s absolutely no external conductor or noise transmission tube, which is hidden and not simple to be discovered and may meet the aesthetic and mental needs of deaf individuals to the highest degree.

Great comfort and fixation: The form of the 3 canal type of hearing aids is closely tailored to the form and size of their individual’s ear canal (the in-the-ear form also contains the ear nail cavity).

Since the form of this hearing aid matches the anatomical arrangement of the individual’s external ear canal, it is comfortable to use and not simple to drop off. High fidelity: Considering that the space between the earphone of the hearing aid and the eardrum is shortened, the aerodynamic sound does not have to go through ear hooks, catheters and ear molds, and is not influenced by wind sound, it may act directly on the eardrum, so noise and distortion could be better controlled.

High-frequency gain: As mentioned above, firstly, the high heeled amplification of the ear auricular cavity itself leaves the sound of 4000-5000Hz amplified by 10dB then transmitted to the microphone of the hearing aid; secondly, since the ear canal system creates the ear canal”blocked”, the amount of the outer ear canal is shortened, so that the resonance frequency peak is shifted forward, and the sound of about 2000Hz is amplified by about 10dB.

The sound of about 2000 Hz is amplified by about 10 dB and acts upon the eardrum. This way, the high-frequency data of speech is efficiently amplified, causing an important growth in auditory resolution. It’s very acceptable for patients with high-frequency hearing loss.

Reduced gain demands: As stated earlier, CIC hearing aids may improve sound gain, increase output, increase headroom, reduce acoustic comments, etc., therefore their gain requirements are decreased.

In other words, a patient with exactly identical hearing loss can require less electricity from a comprehensive ear tube hearing aid than from a cassette or behind-the-ear machine. Since the hearing aid is located deep in the ear, and it’s less influenced by sweat and dust also has less likelihood of being damaged by accidents, which can be helpful to the security of the hearing aid.

Disadvantages of deep ear canal hearing aids:

The size and battery are small, and it is inconvenient to operate and easy to lose for the elderly or those with poor hands dexterity. The output power is limited and is not suitable for patients with severe hearing impairment. The deep part of the ear canal is warm and humid and is easily affected by ear wax and ear canal secretions, and the electronic circuit is more easily damaged.

The close distance between the microphone and the soundhole can easily cause acoustic feedback. It is currently not possible to configure directivity and multi-microphone systems It needs to be customized and cannot be produced in large quantities, so the price is more expensive. As mentioned above, it is not suitable for minors, those with continuous discharge of secretions from the middle ear, and those who have undergone radical otological surgery or deformity of the external auditory canal.
