How do elderly people choose hearing aids?

Clinically, the families of many elderly people who have worn hearing aids report that they have bought hearing aids for the elderly, they don’t wear them, or they wear them when they talk to people. This is mainly because the traditional analog hearing aids use analog linear amplification technology, which has poor noise filtering and distortion, which makes the elderly feel noisy and therefore refuses to wear for a long time.

For older people who are so troubled, try using an all-digital hearing aid. Because the digital hearing aid is a hearing aid that uses digital electronic technology to process the sound, the digital signal is used to segment the sound signal, wide dynamic range compression, multi-channel programming, and noise reduction processing, so that it has intelligent features and can be large. Limit the user’s different hearing needs.

In addition to digitizing traditional hearing aid amplification techniques, such as traditional multi-channel compression techniques, digital hearing aids have produced many new technologies that were previously impossible with analog circuits.

First, intelligent noise reduction

In noisy environments, the effects of using hearing aids can be affected, and patients will feel uncomfortable if they are used in such an environment for a long time. However, digital hearing aids using this technology can analyze the spectrum of environmental signals and track changes in the spectrum to determine the frequency band of the noise and the frequency band of the speech, which can identify and attenuate steady-state noise (such as refrigerators, cars, computers, etc.). Noise) and amplify the voice.

Second, feedback howling processing

The application of digital feedback suppression technology makes the hearing aids no annoying feedback sound (howling), which plays an important role in improving the patient’s language resolving ability.

Third, adaptive directional processing

Scientists have long confirmed that directional microphones can effectively improve the signal-to-noise ratio of hearing aids. Digital hearing aids analyze the signals collected by the front and rear microphones, and can automatically calibrate the matching of the two microphones, which is more flexible according to different sound environments.

Fourth, adaptive acoustic feedback control

Digital hearing aids with this technology can monitor the signal strength of each band at any time, automatically reduce the gain at the feedback band when an feedback occurs or generate an inverted signal to cancel. Adaptive feedback control technology greatly reduces the chance of feedback, making the emergence of open-ear hearing aids possible.

V. Language enhancement (spectral enhancement processing) technology

In patients with sensorineural deafness, the recognition of the sound frequency is reduced, that is, the language recognition power is decreased. Digital hearing aids use spectrum boosting technology to make the difference between vowels and consonants more obvious, in order to improve the speech recognition of deaf patients.

Six, multi-program automatic switching

Under the conditions of analog technology, hearing aids configured with multiple listening programs can only be manually switched to adapt to different listening environments. Digital technology can automatically analyze the current environment and automatically select a suitable listening program, which greatly facilitates the user.

Seven, humanized function

Digital hearing aids have:

1 Low battery prompt: When the battery is low, it can automatically send a reminder to remind the patient to replace the battery.

2 boot delay function: can avoid feedback squeal stimulation when the patient wears the hearing aid.

3 multi-memory programs: to meet a variety of use needs, such as quiet environment, noisy environment, listening to music, making phone calls, etc.

4 Automatically eliminate wind noise.

5 plug ear effect adjustment.

Eight, automatic inductance file

Traditional hearing aids use a toggle switch to switch between the microphone and the inductor, and manual switching when making a call is inconvenient. The hearing aid with this technology can monitor the electromagnetic field strength near the hearing aid at any time, automatically switch to the inductor when the phone is close, and switch back to the microphone after the phone is put down, which is very convenient.

Nine, using log records

The digital hearing aid is a microcomputer. The digital hearing aid with logging function can automatically record the user’s daily hearing aid usage, set the volume, and even the environment, and provide more personalized parameters for automatic fitting.

Ten, audiometry function

By changing the program, the digital hearing aid can also be turned into an audiometer to detect the user’s hearing. Some hearing aids can even test RECD parameters after using some accessories to achieve true ear fitting.

Therefore, the selection of digital hearing aids for the elderly can not only improve the understanding of the language of the elderly, but also help the elderly to restore their hearing.
