项目摘要
The goal of this project is to conduct a study of the speech, voice and music perception abilities
of patients who hear with combined electric and acoustic stimulation (EAS) and to relate speech, voice
and music perception to underlying psychophysical abilities in the region of acoustic hearing. The goal
will be met through experiments and analyses relative to 6 aims. Ami 1is to characterize low frequency
acoustic hearing in patients with residual hearing before and after implantation by assessing auditory
thresholds and by obtaining estimates of nonlinear cochlear processing, frequency selectivity and
temporal resolution. Aim 2 is to assess the effects of acoustic stimulation alone, electric stimulation
alone and combined acoustic and electric stimulation on tests of speech, voice and music recognition.
Ami 3 is to determine the relationships among the psychophysical measures of low-frequency acoustic
hearing and the measures of speech, voice and music recognition. Aim 4 is to compare the performance
of EAS patients, patients with unilateral implants and patients with bilateral implants on measures of
speech, voice and music recognition. Aim 5 is to assess the pitch of stimulation delivered to electrodes
relative to that of pure tones in the region of acoustic hearing and to relate electrical pitch to
computerized radiography assessment of electrode position in the cochlea. Aim 6 is to conduct studies
of filter-band-to-electrode assignments in order to assess (a) whether assigning filter-bands to
electrodes based on acoustic-electric pitch matching (as in Aim 5) produces better speech recognition
than a standard assignment of filter bands and (b) whether overlap in representation of low frequencies
by acoustic and electric stimulation is necessary for maximum levels of performance.
本研究的目的是对儿童的言语、声音和音乐感知能力进行研究
的患者听到与联合电和声刺激(EAS),并与语音,声音
和音乐感知到听觉区域中潜在的心理物理能力。目标
将通过与6个目标相关的实验和分析来实现。AMI 1用于表征低频
通过评估植入前后残余听力患者的听觉听力
阈值,并通过获得非线性耳蜗处理,频率选择性和
时间分辨率目的2是评估单独声刺激、电刺激
单独和组合声电刺激对语言,声音和音乐识别的测试。
AMI 3是确定低频声学的心理物理测量之间的关系
听力和言语,声音和音乐识别的措施。目的4是比较性能
EAS患者、单侧植入体患者和双侧植入体患者的
语音、语音和音乐识别。目的5是评估递送到电极的刺激的音高
相对于声学听觉区域中的纯音的音调,并将电音高与
电极在耳蜗中位置的计算机化放射线照相评估。目标6:开展研究
为了评估(a)是否将滤波器频带分配给
基于声电音调匹配的电极(如Aim 5)产生更好的语音识别
以及(B)低频表示是否重叠
通过声音和电刺激是必要的最高水平的性能。
