Abstract: A remote user interface is provided for connection with an audiologic test apparatus for audiologic testing and comprising a remote user interface housing accommodating a mechanically non-latching switch for selection of one of the right ear or left ear of a patient for testing with the audiologic test apparatus.

Abstract: A member includes a fastener for removable fixation of a housing of a hearing aid, and a hole for removable insertion of a sound tube of the hearing aid in sound proof engagement with the member.

Abstract: An audiologic test apparatus includes: a pump device configured to apply a first pressure to the ear canal; and a processing module for communicatively coupling to the pump device and to a signal generator, wherein the processing module is configured to obtain first acoustic parameter values indicative of an acoustic parameter at the first pressure based on a first broadband signal generated using the signal generator; wherein the pump device is configured to change the first pressure to a changed pressure, and wherein the pump device is also configured to apply a second pressure to the ear canal; and wherein the processing module is also configured to obtain second acoustic parameter values indicative of the acoustic parameter at the second pressure based on a second broadband signal generated using the signal generator, and determine a middle ear resonance frequency based on the first and second acoustic parameter values.

Abstract: An apparatus for covering a left eye and a right eye of a human, includes: a first eye piece configured for covering a left eye of a human; and a second eye piece configured for covering a right eye of the human; wherein the first eye piece and the second eye piece are configured for preventing transmission of visible light; and wherein at least one of the first eye piece and the second eye piece comprises a region that is transparent for electromagnetic radiation with a wavelength range outside a visible range.
