Hearing loss affects 30 million people in the United States, and a subset of these patients have normal low-frequency hearing and ski-sloped high-frequency hearing loss. For these patients, hearing aids alone may not provide adequate benefit. Cochlear implantation alone has been utilized to improve speech perception. The addition of high-frequency electric hearing to low-frequency acoustic hearing in these patients is beneficial. Technical improvements have allowed preservation of low-frequency hearing in cochlear implant recipients, allowing for electric and acoustic stimulation in the same ear with significant improvements in speech perception, sound localization, music appreciation, and quality of life.
听力损失影响着美国3000万人,其中一部分患者低频听力正常,但存在斜坡状高频听力损失。对于这些患者,仅使用助听器可能无法带来足够的益处。单独进行人工耳蜗植入已被用于改善言语感知。在这些患者中,将高频电刺激听力与低频声学听力相结合是有益的。技术进步使得人工耳蜗植入受者能够保留低频听力,从而在同一只耳朵中实现电刺激和声学刺激,在言语感知、声音定位、音乐欣赏和生活质量方面都有显著改善。
