Hearing aids have come a long way in providing an improved quality of life for individuals with hearing impairments. Among the best solutions available today are digital Completely-in-Canal (CIC) rechargeable hearing aids. However, even these advanced devices can sometimes produce feedback noise. In this article, we'll delve into why this happens and how to minimize it.
Understanding Feedback Noise
Feedback noise in hearing aids occurs when sound from the hearing aid's speaker loops back into the microphone, resulting in that annoying whistling or squealing sound. Several factors contribute to this issue, but rest assured, they can be managed effectively.
1. Ear Anatomy Matters
The fit of your hearing aid in your ear plays a pivotal role in feedback prevention. CIC and other hearing aids are designed to fit snugly into your ear canal, which can sometimes lead to feedback if they're not precisely fitted. An audiologist can ensure a proper fit for minimal feedback.
2. Quality Digital Technology
When selecting the best digital hearing aids, choose models equipped with advanced feedback cancellation technology. This technology actively identifies and mitigates feedback before it reaches your ears. For example, the Mimitakara TWS GoodHearing T3 rechargeable hearing aids feature a state-of-the-art chip that is able to detect the presence of feedback and actively cancel it.
3. Rechargeable Convenience
Opting for rechargeable hearing aids is not only eco-friendly but can also contribute to reduced feedback.These devices typically have more stable power sources, helping maintain optimal performance and minimize feedback issues.
Managing Feedback Noise
While the best hearing aids are equipped with feedback cancellation features, there are additional steps you can take to minimize feedback:
Charging the Hearing Aid Case: For hearing aids that come in a case, the earpieces often automatically turn off when they are put back into their case. When the case is low or out of power, the earpieces might not be able to understand that it has been put back and continues to amplify surrounding sounds. Feedback is thus created because of their proximity in the case. Charging the case should prevent this issue.
Regular Maintenance: Clean your hearing aids as recommended by the manufacturer to prevent earwax buildup and component issues.
Proper Insertion: Ensure your hearing aids are inserted correctly into your ear canal.
Volume Control: Adjust the volume to a comfortable level to reduce the risk of feedback.
In conclusion, the best digital CIC rechargeable hearing aids offer remarkable benefits, but they may still produce feedback noise in certain situations. By understanding the causes and implementing preventive measures, you can enjoy clearer, more comfortable hearing without the nuisance of feedback.
