Causes of low-frequency hearing loss in the ear

Low-frequency hearing loss in the ear is generally caused by conditions such as earwax blockage, external otitis, or eardrum perforation. Treatment should be administered according to medical advice based on the underlying cause.

1. Earwax blockage: In daily life, it's normal for the external auditory canal to have earwax. However, excessive accumulation can lead to local blockage and subsequent hearing loss. In such cases, no special treatment is required—simply removing the earwax from the ear can relieve symptoms.

2. External otitis: External otitis can cause low-frequency hearing issues and hearing loss, primarily due to inflammation-induced mucosal edema and exudate. After these symptoms appear, patients may apply ichthammol ointment locally or receive infrared radiation therapy.

3. Eardrum perforation: When an eardrum perforation occurs, its vibratory capacity decreases, affecting hearing and leading to low-frequency hearing problems and hearing loss. A tympanic membrane patch procedure, performed under a doctor’s guidance, may be used for treatment.

Besides the above-mentioned conditions, inner ear damage can also cause discomfort.
