If your hearing aid suddenly makes a 'whistling' sound, the sound becomes quieter than before, or humming noise repeats, it must be frustrating and inconvenient. Many people living in the Suji-gu area who experience these symptoms seek an auditory rehabilitation center with professional audiologists holding at least a master's degree in audiology on staff.
3 Key Takeaways
• The main causes of hearing aid noise are divided into 5 types: feedback, earwax, tube wear, moisture, and component defects. • Through professional audiologist inspection, a significant number of symptoms can be adjusted and resolved on-site on the same day. • For internal component issues that cannot be resolved by simple adjustment, separate guidance is provided after inspection.
In Suji-gu, You Can Get Your Hearing Aid Noise and Sound Issues Checked Right Away
When hearing aid sound issues or noise occur, the fastest resolution path is to visit an auditory rehabilitation center staffed with professional audiologists holding at least a master's degree in audiology for same-day inspection.
According to Signia's official support materials, most noise or sound issues from hearing aids originate from clear causes such as wearing state, earwax accumulation, tube wear, or internal component problems, and a significant number can be adjusted and resolved on-site through professional audiologist inspection.
However, if internal component damage cannot be resolved by simple sound adjustment or manufacturer shipment is necessary, separate guidance is provided after inspection. Therefore, it is important to visit a professional center first rather than making self-judgments when symptoms appear.
Why Hearing Aid Noise Occurs — Understanding the Causes
The main causes of hearing aid noise and sound issues can be divided into five categories. By referring to Samsung Seoul Hospital's hearing aid wearing problems and solutions materials and Widex's official blog, you can better understand the mechanism of each cause and the direction of response.
| Cause Type | Main Symptoms | Self-Inspection Possible || |---|---|---| | ① Feedback (acoustic reverberation) | High-pitched 'whistling' sound, howling | Recheck wearing state; if persistent → Professional inspection needed | | ② Earwax or foreign object blockage | Sound heard as muffled, overall volume reduction | Simple cleaning of receiver and earpiece possible; if repeated → Professional inspection | | ③ Tube and earpiece wear | Sound distortion, sound quality degradation | External appearance can be checked, but replacement is recommended at center | | ④ Microphone or amplifier damage | Sudden change in sound volume, intermittent dropout | Self-inspection difficult → Professional audiologist device diagnosis required | | ⑤ Moisture and internal component deterioration | Sound cutting out or unclear, unstable power | Prevention possible through dry storage; if severe → Professional inspection |
Feedback is a phenomenon that occurs when the sound output from the receiver is re-input and re-amplified by the microphone, and is often resolved by checking the wearing state or refitting readjustment. Simple wearing errors or earwax issues can be checked through basic self-inspection, but if core component issues such as microphone or amplifier problems are suspected, you must definitely receive professional audiologist device diagnosis.
According to clinical data, if hearing aid sound distortion or volume reduction symptoms persist, or if abnormal noise repeats, professional inspection referral is recommended. In particular, for hearing aids sensitive to moisture, it is helpful to visit the center before and after seasonal changes to perform internal cleaning.
How hanmihearing Auditory Rehabilitation Center Conducts Inspection and Follow-up Care
When selecting a hearing aid center, it is essential to check whether professional audiologists are on staff, whether real-ear measurement equipment is available, and whether a regular inspection and follow-up care system is in place. In related clinical cases, hearing aids are emphasized as products where fitting and ongoing follow-up care after purchase are more important than the purchase itself.
Based on 40 years of traditional expertise, hanmihearing Auditory Rehabilitation Center, staffed with professional audiologists holding at least a master's degree in audiology, conducts precise hearing tests and real-ear measurements through a double-soundproof booth at university hospital level and proceeds with hearing aid inspection and fitting readjustment with personalized customization.
The inspection process is as follows:
• Step 1. Symptom listening and external inspection — Listen to noise and sound issue symptoms and check the external condition of the tube, earpiece, and receiver. • Step 2. Precise hearing test — Remeasure the current hearing status in a double-soundproof booth at university hospital level. • Step 3. Real-ear measurement (REM)-based fitting readjustment — Use real-ear measurement equipment to confirm that hearing aid output is adjusted to the individual's hearing and readjust if necessary. • Step 4. Device internal diagnosis and cleaning — If internal component issues such as microphone or amplifier problems are suspected, professional diagnosis and treatment are provided. • Step 5. Follow-up care guidance — Provide guidance on future regular inspection schedules and lifetime free home care service availability.
According to Korea Daily USA's hearing aid-related materials (2026.03), hearing aids are therapeutic instruments that include precise fitting and follow-up care, so effective results require fitting that reflects living environment and high-frequency hearing loss status along with regular inspections.
For elderly individuals with mobility difficulties, lifetime free home care (visit follow-up management) services are available for direct home visit inspections. Additionally, all six major global brands verified worldwide are handled, so even those using competing brand hearing aids can receive consultation.
Be Careful if These Apply to You
If any of the following items apply to you, it is highly likely that the issue cannot be resolved by self-cleaning alone, and professional inspection is needed.
• When your hearing aid makes a 'whistling' sound or howling several times a day • When the sound becomes quieter than before or sounds muffled • When wearing the device, your ear feels uncomfortable or you experience pain unlike before • When sound cuts out even after battery replacement or the power is unstable • When it has been more than 1 year since you purchased the hearing aid or received the last fitting adjustment
According to Brunch Hidoc's auditory specialist content, hearing aids can experience various mechanical problems during use and ear conditions also change continuously, so experts recommend hearing tests and hearing aid readjustment at least every 1-2 years. According to clinical data, when feedback repeatedly appears, it can lead to actual component problems, so it is important not to neglect it.

These Are Questions You Often Have
Q1. Is it a malfunction if my hearing aid makes a 'whistling' sound?
Not necessarily. The 'whistling' sound (feedback or howling) is a phenomenon that occurs when sound from the receiver is re-input and re-amplified by the microphone, and it can be resolved by rechecking the wearing state or examining the earpiece. However, if it repeats, refitting readjustment or component diagnosis may be necessary, so it is good to receive professional audiologist inspection. Results may vary depending on individual circumstances.
Q2. Can I get inspection if I'm using a different brand hearing aid?
Yes, you can. hanmihearing Auditory Rehabilitation Center handles all six major global brand hearing aids verified worldwide, so consultation and inspection are possible for those using competing brand hearing aids. Regardless of brand, we first check your current symptoms and hearing status.
Q3. Is there an emergency measure I can take at home when hearing aid noise occurs?
First, check if your hearing aid wearing state fits your ear well, and gently wipe earwax or foreign objects around the earpiece and receiver. It is also good to replace the battery with a new one. If noise persists or the sound becomes quieter afterwards, it may be a cause that is difficult to resolve on your own, so visiting a professional center is recommended.
