Hearing loss can affect individuals of all ages, from newborn babies to elderly individuals enjoying their quiet moments. According to the 2019 Global Burden of Disease Study, approximately 94 million people in China suffer from moderate to severe hearing loss, making up 22.3% of all cases of hearing loss, from mild to complete deafness. Over time, hearing loss can have severe physical and mental consequences, affecting learning, work, and social interactions. For the elderly, it is also a major risk factor for depression, pessimism, loneliness, and cognitive decline.
As an extension of your ear, choosing the right hearing aid requires prioritizing two key factors: clear sound and comfortable wear.
The electronics within a hearing aid directly impact its effectiveness. Differences in electronic circuits and signal processing modes (such as analog, digital, or programmable circuits) determine the quality of sound. Digital and programmable hearing aids generally offer superior sound quality, accuracy, and better speech recognition, though they tend to be more expensive than their analog counterparts.
Here are some essential factors to consider when choosing a hearing aid:
Sound Gain: This refers to the amplification level of sounds. The “maximum sound gain” is the upper limit for amplification. For individuals with mild hearing loss, a lower gain of around 30dB might suffice. For those with more significant hearing loss, a higher gain of 45dB or more is recommended.
Number of Processing Channels: More channels allow finer control over sound frequency ranges, improving sound quality and realism. Generally, 6-8 channels are enough for most needs, but more channels usually result in better sound quality, albeit at a higher price.
Sound Delay: Shorter sound delays reduce interference between processed and natural sounds. Although modern hearing aids process sound quickly, any significant delay between the processed sound and natural sound can lead to distortion. The shorter the delay, the more natural the listening experience.
Additional Features: Hearing aids do more than just amplify sound. They employ smart algorithms to enhance useful sounds while minimizing irrelevant noise. Look for features like noise cancellation, wind noise reduction, feedback suppression, and the ability to automatically adjust based on the environment.
The choice of features depends on the specific model and its signal processing capabilities, which directly affect the price. Generally, more features and better performance mean a higher cost. If your budget allows, the more advanced features will provide greater comfort and better results.
For individuals with hearing loss in both ears, it’s typically recommended to use hearing aids in both ears, as this improves sound localization, directional hearing, and speech understanding in noisy environments. If budget is a concern, two more affordable hearing aids may be more beneficial than a single, more expensive device.
Hearing aids are available in various styles, including behind-the-ear (BTE), in-the-ear (ITE), and in-the-canal (ITC) models. Over-the-counter (OTC) hearing aids are usually of the ITE type.
Each style has its advantages and limitations:
BTE models are suitable for children, as their ear structure is still developing. They are also ideal for individuals with severe hearing loss.
ITE and ITC models are more discreet and aesthetically pleasing, especially for teenagers, with the ITC being smaller and less visible, fitting well into the ear canal for improved sound quality and directionality.
There is no one-size-fits-all hearing aid. The choice depends on factors like hearing assessment, degree and type of hearing loss, age, preferences, and budget. When selecting a hearing aid, it’s crucial to consider all these aspects to find the one that works best for you or your loved one.
For people with hearing loss, finding the perfect hearing aid is about more than just amplification—it’s about restoring a connection to the world around them.
