    • An instrument configured to test the middle-ear function of a test subject, such as in tympanometry and impedance audiometry is provided. The instrument comprises an ear probe for insertion in an ear of test subject, the ear probe comprises an acoustic output unit comprising a receiver, the acoustic output unit being configured to provide a stimulus into the ear of the test subject via said receiver, an acoustic input unit comprising a microphone, the acoustic input unit being configured to receive a reflected part of said stimulus via said microphone and provide an electrical input signal, an ear-probe body for accommodating said microphone and said receiver, and an ear-probe tip comprising a tip opening for outputting said stimulus and receiving said reflected part of the stimulus, wherein the ear-probe tip comprises a sound tube with a longitudinal axis (A), where said sound tube provides access between a receiver opening and a microphone opening, respectively, and said tip opening, which receiver opening and microphone opening are arranged at a distance (L) from said tip opening along said longitudinal axis (A), and wherein the instrument is configured to provide said stimulus comprising one or more frequencies above 226 Hz into the ear of the test subject via said receiver.
