Abstract: An instrument comprising an ear probe for insertion into an ear canal of a test subject is provided. The ear probe comprising an acoustic output unit comprising at least one speaker, the acoustic output unit being configured to provide at least one stimulus into the ear canal of the test subject via said speaker, an acoustic input unit comprising at least one microphone, the acoustic input unit being configured to receive a reflected part of said stimulus via said microphone and provide an electrical input signal, where the instrument further comprises a signal-processing unit connected to the acoustic output unit and to the acoustic input unit, where the signal-processing unit is configured to generate at least a first and a second stimulus and to provide said at least first stimulus and second stimulus to said acoustic output unit, and where the acoustic input unit is configured to receive a reflected part of said at least first stimulus and second stimulus.

Abstract: Disclosed herein are embodiments of an acoustic measurement device configured to provide acoustic property values for objective ear-condition evaluation of a patient's ear, in particular a human's ear. Said acoustic measurement device can be configured to be positioned within an ear canal of said patient and configured to take a resting position within said ear canal. Embodiments of the acoustic measurement device can include an air-pump arrangement, said air-pump arrangement, at least in said resting position, being in fluid connection with said ear canal through at least one tube running via said ear probe.

Abstract: An instrument configured to test the middle-ear function of a test subject, such as in tympanometry and impedance audiometry is provided.
