Abstract

The invention discloses a filter device and a method of manufacturing the filter device. The filter device for a hearing test probe extends along a center axis in a first direction from a first end to a second end. The filter device comprises: a first part having a first filter structure, a second part having a second filter structure, a first channel extending along the center axis. The first part and second part are joined together, and the first filter structure and the second filter structure define a filter element with a first set of filter openings for the first channel.

Description

technical field [0001] The present invention relates to a filter device, for example for hearing test equipment or the like, for preventing earwax (commonly referred to as cerumen) from entering a compartment containing delicate equipment such as a microphone and / or loudspeaker. The compartment may be a compartment for a hearing test probe used to perform hearing tests such as tympanometric and / or otoacoustic emission tests. Background technique [0002] In order to perform a hearing test, a probe is inserted into the ear canal of the person to be tested. The probe may hold an audio device, such as a microphone and / or one or more speakers. These components can be damaged or altered by the wax in the human ear. Thus, the filter arrangement may be applied to the probe between the probe assembly and the distal end of the probe inserted into the ear canal. [0003] In order to perform a hearing test, the filter unit needs to pass sound and air. At the same time, the filter n...
