FAQs
No, otc hearing aids are designed for mild to moderate hearing loss and are not suitable for minors, being intended for middle-aged and elderly individuals.
Mild (26–40 dB) hearing loss: Difficulty hearing in noisy environments; requires others to speak closer or louder.
Moderate (41–55 dB) hearing loss: Challenges with everyday conversation; necessitates increased volume for television or telephone calls.
Moderately severe (56–70 dB) hearing loss: Only loud speech or shouting is audible.
Severe (≥70 dB) hearing loss: Only very loud sounds, such as vacuum cleaners, are audible.
Over-the-counter hearing aids typically require a 2–6 week adaptation period, as the brain needs time to relearn processing sounds.
Days 1–3: Wear for 1–2 hours daily in quiet environments.
Weeks 1–2: Gradually extend wear to 4–6 hours, testing use in varied settings.
Weeks 3–4: Adjust volume or modes, practising communication in noisy environments.
Weeks 5–6: Establish long-term wearing habits, maintaining regular device cleaning and upkeep.
①Sound appears excessively loud, noisy, or includes previously inaudible noises (e.g., refrigerator hum, footsteps, birdsong): Prolonged absence of high-frequency sounds reduces auditory sensitivity. When amplifiers restore these frequencies, they may initially seem ‘disturbing’.
②One's own voice sounding strange, muffled, or ‘hollow’: The hearing aid amplifies air-conduction sound, which combines with bone-conduction sound. The brain requires readaptation.
③Feeling focused on hearing yet struggling to understand speech in noisy settings: New auditory input refocuses the brain on auditory processing. However, background noise still impacts speech intelligibility even with hearing aids, requiring training and adaptation.
①Replace with suitable ear tips; left and right ears may require different tip sizes.
②First insert the hearing aids, then switch on the device after proper placement.
Hearing aids with in-ear infrared sensors switch off automatically when removed. Over-the-counter hearing aids without infrared sensors do not switch off automatically when removed. However, rechargeable hearing aids with charging cases will switch off automatically when placed inside the charging case.
