The broad conclusion is that each brand of hearing aid has similar results. If you judge hearing aids by their effectiveness, each brand of hearing aid is equivalent on a large scale (if you count the experience of many people), and there is no absolute conclusion as to who is better or worse.
The core function of hearing aids is to amplify the sound. No matter the big international brands, including some of their sub-brands, they all produce products that meet the international and domestic electroacoustic standards and can accurately complete the sound amplification function, which is the core function of hearing aid products.
Is there a difference between hearing aid brands?
Of course, there is, the main difference is the difference in tone, some people can't understand the tone, to use an analogy, your two friends say the same sentence to you, for example, they both ask you: "Where to play on vacation?" If both friends say the same thing with their backs to you, you can clearly understand the content and distinguish the person who said it.
Two hearing aid brands are just like two friends, with different tones. But because the human articulatory organs (vocal cords, tongue, oral-nasal resonance cavity and other organs) are more different, you can easily distinguish the different tones of two people.
The difference in the articulation part of hearing aids (speakers, basically different models of speakers from one manufacturer) is indeed very small. Of course, with the unique concept of the brand chip processing sound and the difference in microphone sensitivity, they still present different tones, but the difference is much smaller.
Even if the difference in timbre is very small, many customers can still tell the difference, and some of them have timbre preference, that is, they like the timbre of a certain brand of amplified sound, and they will say that a certain brand is good. For these reasons, it is possible that different users prefer different brands of sound, but if you have not tried several brands, it is impossible to know which brand of hearing aid you prefer.
If you are an adult or a child with discernment skills, the criteria for choosing a good hearing aid is their ears, and you have to try out several brands of hearing aids, and they will choose the tone they like. The reason for the premise that there are adults and children with discriminating skills is that many young children do not or will not express their feelings about tones, so it would be totally untenable for someone to say that a certain brand is better for children.
For children, many parents like to inquire what brand of hearing aids other children use and then see if the child speaks clearly to determine their own choice. If you see more children, you will find that every hearing aid brand has children with poor results.
The reason is that different hearing aid brands are equivalent in terms of the child's ability to understand speech, and the factor that affects understanding is the dispenser who has mastered the scientific dispensing process. The results you will see in your child's speech rehabilitation will be combined with the efforts of the rehabilitation learning process.
For adults, if the dispenser is patient and willing to spend time for you to try out different brands of hearing aids at different prices (the dispenser's organization must be a multi-brand business), and is also willing to let you take home different hearing aids for a few days, you can spend half a month to a month on your own to try them out and then decide which one to choose.
There are some ways to measure the quality of hearing aids, such as the repair probability of the hearing aid. The probability of repair is often determined by the various protective features of the hearing aids, especially the water and moisture resistant features.
