Hearing above 2,000 Hz is called the high-frequency zone. Above 2,000 Hz, if hearing loss is demonstrated by a pure-tone audiometric threshold examination, it is called high-frequency hearing loss. High-frequency hearing loss does not necessarily have a significant impact on the patient’s daily communication. High-frequency hearing loss may have a strong relationship with drug-induced or noise-induced, and many elderly people exhibit high-frequency hearing loss. High-frequency hearing loss is mainly related to inner ear hair cell damage, and most of these patients show very low resolution and poor resolution of sound, which means that they can hear the sound, but can’t distinguish the content of the sound. For this situation, you can use the drugs of nutritive nerve, expanding blood vessels, improving microcirculation of the inner ear, to carry out comprehensive symptomatic treatment, and the recovery effect of patients with high-frequency hearing loss is not very ideal.
