What is an simulator? -- Amplify all sounds indiscriminately

Many people think that "a hearing aid that can amplify sound is a hearing aid", but simulators not only amplify useful sounds but also noise. Even cheap simulators themselves can produce noise that is hard to adapt to when in operation. In addition, everyone's hearing impairment is different. Hearing AIDS need to be able to independently adjust the gain of different frequency bands to achieve precise compensation, but simulators cannot

What are the differences between analog hearing AIDS and digital hearing AIDS?

01 Working Principle

Simulator: All frequencies of sound are enhanced without difference

Digital hearing AIDS: Digital processing, independent adjustment of gain in different frequency bands

02 Adaptation Method

Analog machine: It can only adjust the volume of the sound and the range is limited, and it cannot provide personalized compensation

Digital hearing AIDS: Customized parameters based on audiogram results through professional software

03 Applicable Environment

Simulator: Only suitable for quiet environments

Digital hearing AIDS: Can intelligently recognize the environment and support Bluetooth function

04 Noise Processing

Simulator: It has no noise reduction function. In a noisy environment, you can't hear clearly and it's even noisier

Digital hearing AIDS: AI algorithms dynamically suppress noise and highlight human voices

Beware of the three major damage risks of simulators, which are more terrifying than not hearing clearly!

"Even if the effect is poor, can't we just make do with it for a few months?" "

Many people buy simulators for their parents with this mentality, but they don't realize that the harm it causes is even more serious than "not hearing clearly"

Risk 1: Excessive amplification of sound can damage residual hearing

The cochlear organ is the organ within the cochlea that senses sound. The hair cells within it sense the mechanical stimulation of sound through the cilia at the top, which is the key to perceiving sound. The sound amplified indiscriminately by the simulator cannot be precisely compensated according to the individual's hearing impairment condition. This may cause the intensity of certain frequencies of sound to exceed the tolerance range of the ears. Long-term use may damage the inner ear hair cells, thereby affecting residual hearing.

Risk 2: Delaying the golden treatment period

There are many different conditions of hearing loss. Early detection, early diagnosis and early intervention should be carried out. We should strive to actively carry out standardized treatment during the golden treatment period and do our best to save hearing. Wearing an simulator without a clear understanding of the situation can easily lead to missing the golden period for hearing reversal.

Risk 3: Health hazards

Hearing loss may be a "signal" of illness. Otitis media, otosclerosis, and even hypertension and diabetes may all affect hearing. If one doesn't go to the hospital for a check-up and starts wearing a simulator right away, it may delay the treatment of these diseases. Some simulators can easily cause ear discomfort, such as a stuffy and painful ear canal, and even increase the risk of otitis media and otosclerosis.

When choosing a hearing aid, remember these three steps!

Rather than buying an analog device just to save money and "harm your ears", it's better to spend time choosing the right and reliable equipment. This way, you won't waste money and your hearing won't be damaged! Remember these three steps

The first step: Take a hearing test first and don't place orders blindly

First, go to the ENT department of a hospital or a regular hearing center for a test - to figure out what kind of hearing loss it is and the extent of the damage. This is the "foundation" for choosing a hearing aid, just like having an eye test before getting glasses

Step 2: Reject "buy and use immediately"

Before purchasing, ask the merchant first: "Is this a digital hearing aid?" " "Do you need professional fitting?" " If the other party says, "No need for fitting. Just buy it and it can be used," then pass it directly.

Step 3: Look at the product and the service

Find out whether the product can intelligently reduce noise, whether it is equipped with an anti-loss rope, a remote control, how its waterproof performance is, whether it has an automatic drying function, and whether it can work simultaneously with Bluetooth and hearing aid functions... Check the medical device registration certificate of the product, after-sales service, and whether there is a trial period for wearing

Finally, I want to say: There is no room for compromise in hearing health. Sound is an important element that constitutes our colorful lives, and we must cherish it well
