How to choose a comfortable hearing aid for your parents?

The old concept believes that conductive deafness is the best user of hearing aids. In the past 30 to 40 years, international hearing aids have developed rapidly, with various performances and high quality. They can almost meet the needs of more than 90% of deaf patients, especially large ones. Most sensorineural hearing loss benefits the most.

① Deaf patients need to undergo medical treatment or surgery, and the disease has been completely stabilized before considering hearing aids. For newly-occurring deafness or those who are in the active period, the decision can be made 1 year after resting. Patients with hereditary hearing impairment should use hearing aids with caution, preferably under the guidance of audiologists.

② Air conduction hearing aids are not required for severe otitis external, otitis media, and full atresia of the external auditory canals. Bone conduction can be considered. Air conduction hearing aids are suitable for other types of deaf patients.

③ Pure tone hearing test should be done before selection, and appropriate hearing aids should be selected according to the audio-gram. For patients with sensorineural hearing loss, suprathreshold function or language audiometry should be tested as much as possible to determine the effect.

④ Hearing aid users should be provided with a trial period of 2 to 3 weeks, which has become a routine in some countries. In this way, the deaf can repeatedly adjust various control knobs under the guidance of specialized personnel, and select the most suitable hearing aid to obtain satisfactory results.

⑤ If conditions permit, ear-grade hearing aids should be used first for patients with hearing loss below 90dB, and box-type hearing aids can be considered for those with hearing loss above 90dB.

⑥ Using a hearing aid with one ear can generally relieve the difficulty of hearing, but when conditions permit or according to personal preference, use binaural hearing aids. Binaural hearing aid has become a development trend, and the use of binaural hearing aid for speech rehabilitation for deaf children should be generally promoted, which has many advantages.
