Benefits of In-Canal Hearing Aids
Compared with behind-the-ear and in-the-ear hearing aids, the advantages of ear canal hearing aids include:
① The shape is small, which can basically meet the aesthetic requirements of patients, and is more comfortable to wear.
② Located in the ear canal, it retains the normal structure of the auricle, which is more in line with the physiological and acoustic characteristics of the human ear, and helps to improve sound gain and sound source localization.
Disadvantages of In-Ear Hearing Aids
Disadvantages of an ear canal hearing aid include:
① As with in-ear hearing aids, since the ear canal of a child is not developed and shaped, the shell needs to be replaced regularly, so children should use it with caution.
② The ear canal hearing aid is only suitable for patients with mild or moderate hearing loss. At present, the ear canal hearing aid with the highest power is only suitable for patients with an average hearing threshold of 90 to 95 dB.
③ The battery and volume adjuster of the in-ear hearing aid are smaller than the in-ear hearing aid, so it is more difficult to operate.
④ As mentioned earlier, due to the smaller internal space, the ear canal hearing aid is more likely to generate acoustic feedback, and it cannot be connected to the FM system.
⑤ As with in-ear hearing aids, in-ear hearing aids are located in the ear canal and are more susceptible to the effects of radon.
⑥ As with in-ear hearing aids, they can also produce ear plugging effects.
