A new measurement system has been developed for hearing research. Targeted especially for otoacoustic emissions, it is flexible enough for a variety of tests. Performance improvements include extended bandwidth, reduced distortion, undistorted SPL up to 90 dB, and lower noise. Traditionally, hearing research has been limited to 5 to 10 kHz, due to the difficulty of controlling acoustic pressure at the tympanic membrane. This system can be combined with Forward Pressure Level or other techniques for accurate prediction of SPLs up to 20 kHz in humans and even higher in laboratory animals. The system consists of a probe with three drivers and four microphones, along with appropriate amplifiers and calibrator. This system can measure high frequency otoacoustic emissions as a potential indicator of early onset of hearing loss.
