Our ability to hear is reflected in low-level acoustic signals emitted from the ear. These otoacoustic emissions (OAEs) can be measured with an acoustic probe assembly coupling one or more small loudspeakers and microphones into the sealed ear canal. The electroacoustic instrumentation of commercial probe systems allow for detailed studies of OAEs emitted between 0.5 and 6-8 kHz. Few studies report OAE measurements below 0.5 kHz. This paper is a preliminary report of an OAE probe aimed at making OAE measurements from 0.03 to 3 kHz. The range 0.5-3 kHz was included to study lower-frequency OAEs with reference to standard-range OAEs.
