Sentence examples for probe microphone from inspiring English sources
Test results show that the calibrator can calibrate each probe microphone within ±0.5 dB up to 2 kHz, and within ±1 dB up to 4.9 Hz with a confidence level of 95%.
The system used two identical sound sources connected separately to an ER-10B+ probe microphone (Etymōtic Research, Elk Grove Village, IL).
Sound was played at 70dBSPL and 90dBSPL, calibrated using a probe microphone (Model ER-7C, Etymotic, Inc, Elk Grove Village, IL).
The stimuli were generated digitally and were compensated for the acoustic transfer function measured with a probe microphone near the eardrum.
The purpose of this study was to determine how to quantify the effects of air leaks during ear-canal probe microphone measurements and to develop objective criteria to detect their presence.
Because of natural amplification of the external ear canal, for the purpose of this study, the real-ear acoustical characteristics in terms of sound frequency spectrum (ie, frequency response) and SPL were investigated using a probe microphone at a position near the eardrum.
The potential for air-leak artifacts is also a concern for other ear-canal pressure measurements that require placement of probe-microphone systems in the ear canal.
The purpose of this study was to determine the size of air leak that can impact ear-canal probe-microphone measurements and to develop objective criteria to detect the presence of such air leaks.
The ear canal sound pressure level (SPL) was recorded with a calibrated probe tube microphone (ER-7C Etymotic Research) with the tip of the flexible probe tube (ER7-14C, Etymotic Research) positioned approximately 2 mm distant from the tympanic membrane.
A coupled waveguide model is developed that represents sound transmission in a flowing fluid which contains a windscreened microphone probe.
General transform relations are established between the sound pressure auto- and cross-spectral densities measured by using a two-microphone probe and the corresponding sound pressure data for the forward- and the backward-travelling wave components.
