点击诱发耳声发射（CEOAE）和行为阈值之间的关系尚未探讨5 kHz以上，由于CEOAE测量程序的限制。使用新技术测量行为阈值和高达16 kHz的CEOAE。一个长的圆柱形管的8毫米直径，作为一个反射少的终端，被用来校准听力刺激和设计一个宽带CEOAE刺激。第二次点击提出了15分贝以上的探针点击水平，在44分贝的范围内变化，和非线性残差过程中提取的CEOAE从这些点击响应。在一些听力正常的受试者（年龄14-29岁）中，CEOAE频谱能量和潜伏期的测量值高达16 kHz。听力阈值测量使用自适应的是-否程序。CEOAE和行为阈值的比较表明，使用CEOAE筛查高频听力损失的临床潜力。CEOAE潜伏期确定的平均，过滤，时间包络的峰值降低到1毫秒，增加频率高达16 kHz。个体CEOAE包络线包括与相干反射源一致的压缩增长、较长延迟分量和与失真源一致的线性或膨胀增长、较短延迟分量。这两个组件的包络延迟近似不变的电平。
Relationships between click-evoked otoacoustic emissions (CEOAEs) and behavioral thresholds have not been explored above 5 kHz due to limitations in CEOAE measurement procedures. New techniques were used to measure behavioral thresholds and CEOAEs up to 16 kHz. A long cylindrical tube of 8-mm diameter, serving as a reflection-less termination, was used to calibrate audiometric stimuli and design a wideband CEOAE stimulus. A second click was presented 15 dB above a probe click level that varied over a 44 dB range, and a nonlinear residual procedure extracted a CEOAE from these click responses. In some subjects (age 14-29 years) with normal hearing up to 8 kHz, CEOAE spectral energy and latency were measured up to 16 kHz. Audiometric thresholds were measured using an adaptive yes-no procedure. Comparison of CEOAE and behavioral thresholds suggested a clinical potential of using CEOAEs to screen for high-frequency hearing loss. CEOAE latencies determined from the peak of averaged, filtered, temporal envelopes decreased to 1 ms with increasing frequency up to 16 kHz. Individual CEOAE envelopes included both compressively-growing, longer-delay components consistent with a coherent-reflection source, and linearly- or expansively-growing, shorter-delay components consistent with a distortion source. Envelope delays of both components were approximately invariant with level.
