Why Do Hearing Aids Sound Noisy? 5 Common Causes & Solutions

1. Long Duration of Hearing Loss

The auditory center in the brain is near the memory center. When hearing loss goes untreated for a long time, the brain gradually forgets the meaning of the sounds it no longer hears.

For individuals with long-term untreated hearing loss, putting on hearing aids for the first time can be overwhelming. The previously silent world suddenly becomes filled with unfamiliar sounds, which the brain interprets as "noise" because it has forgotten what they are. This is why a long adaptation period is crucial. Patience and consistent use allow the brain to relearn how to process these sounds effectively.

2. Improper Fit or Feedback

Hearing aids are precision instruments. A proper seal in the ear canal is essential. If the device isn't inserted correctly or the dome/mold doesn't fit snugly, sound can leak out and be re-amplified by the microphone, causing an annoying whistling feedback.

Solution: New users should practice correct insertion and consult their hearing care professional for tips. A well-fitted device from a reliable hearing aid factory like Greenwattz is the first step to comfort.

3. Inaccurate Fitting and Programming

Every hearing loss is unique, requiring specific frequency responses. If the hearing aids are not programmed correctly, sounds may exceed the user's comfort levels or amplify background noises too much.

Solution: This requires close collaboration between the user and a professional audiologist. Fine-tuning is a process. At Greenwattz, as a professional hearing aid supplier, we provide comprehensive support materials for our partners to ensure optimal fitting for end-users.

4. Low Performance of the Hearing Aids

A basic function of hearing aids is to amplify sound. However, the environment is full of noise. Lower-performance devices amplify all sounds equally—speech and noise together—which can create a chaotic and "noisy" experience.

Advanced digital hearing aid technology, like that used in Greenwattz products, employs sophisticated algorithms to reduce background noise while prioritizing speech. We advise against using outdated analog amplifiers, which simply amplify everything and are often sold online at low prices. As a high-quality hearing aid manufacturers China, we encourage potential hearing aids distributors to choose products that offer genuine comfort and clarity.

5. High Internal Noise (Noise Floor)

The "noise floor" is the low-level sound produced by the hearing aid's electronics itself, even in a quiet environment. While all electronic devices have some inherent noise, it should be negligible.

This becomes noticeable in two cases:

• Poor-Quality Devices: Analog hearing aids often have a very high noise floor.
• Over-Powered Devices: Selecting a device with significantly more power than needed can make the internal noise more audible. Accurate power selection is key. Greenwattz, as an ISO certified hearing aid factory, ensures our products meet strict standards for low internal noise, providing a clean and clear sound experience.

A "noisy" hearing aid is often a sign of an underlying issue that can be addressed through proper fitting, quality technology, and a realistic adaptation period. By understanding these causes, hearing aid suppliers and clinics can better guide their clients. For B2B hearing aid suppliers looking for reliable hearing aid factory partners, Greenwattz offers high-performance, durable hearing aids designed to minimize these common problems, ensuring end-user satisfaction.
