This paper discusses the technology of combined electric and acoustic stimulation (EAS) of the auditory system, which is a new therapy for the patients suffering from severe to profound high- and mid-frequency hearing loss but still having their low-frequency hearing. EAS uses hearing aid and cochlear implant technology together in the same ear. The hearing aid acoustically amplifies at low-frequencies, while the cochlear implant electrically stimulates at mid- and high-frequencies. The inner ear processes acoustic and electric stimuli simultaneously. This technique can provide substantial benefit in speech understanding for individuals with severe high-frequency hearing loss and can maintain their residual lower-frequency acoustic hearing. The study of EAS would significantly enhance the conventional cochlear implant therapy and benefit the patients afflicted with severe to profound hearing loss.
本文讨论了听觉系统的电声联合刺激（EAS）技术，这是一种针对患有重度至极重度中高频听力损失但仍保留低频听力的患者的新疗法。EAS在同一耳中同时使用助听器和人工耳蜗技术。助听器在低频进行声学放大，而人工耳蜗在中高频进行电刺激。内耳同时处理声学和电刺激。该技术可为重度高频听力损失患者在言语理解方面带来显著益处，并能保留其残余的低频声学听力。对EAS的研究将显著改进传统的人工耳蜗治疗方法，并使患有重度至极重度听力损失的患者受益。
