Abstract
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 reflectionless 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.
