An audiological test apparatus adapted for performing audiological measurements in a human ear, and comprising an ear probe tip (14) adapted for insertion into the ear canal of the human ear and having an acoustic output port (35) that is acoustically connected via a first air conduit (36) to a loudspeaker (15) for emission of sound into the ear canal, and an acoustic input port (37) that is acoustically connected via a second air (38) conduit to a microphone (16) for reception of sound from the ear canal. The audiological test apparatus further comprises a housing (1) configured to be worn at the human ear and enclosing an air pump (11) and a controller (28), and the air pump (11) is connected via an air duct (18) to a pump output port (39) arranged in the ear probe (14) for providing a pressure to the ear canal, and the controller (28) is configured for providing an output signal to the loudspeaker (15) and for receiving an input signal generated by the microphone (16) in response to the sound from the ear canal.
