Definitions
- a new member is provided for use in a test box for testing hearing aids.
- test hearing aids in a test box for quality control and/or for adjustment purposes.
- the sound output of the hearing aid to be tested is connected to a test microphone in a soundproof manner using an adaptor and a coupler such as a 2cc coupler.
- One or more loudspeakers in the test box generate sound during the test for reception and processing by the hearing aid to be tested and the sound output by the hearing aid is guided towards test microphone in the test box.
- a reference microphone is positioned adjacent a microphone of the hearing aid to be tested in order to measure the actual level of the sound received by the hearing aid.
- the test box is sound proof so that sound from the surroundings is prevented from interfering with the testing of the hearing aid.
- US2009316921A disclose an apparatus for connecting a hearing aid tester to a sound emitting portion of a hearing aid that fits into the concha or ear canal of a user, the apparatus including a body having a front end and a rear end, a passage within the body for receiving the sound emitting portion and extending from an opening near the front end to an opening near the rear end, the opening near the front end for connecting the passage to the hearing aid tester, and a resilient surface within the passage that resiliently deforms when the sound emitting portion is received in the passage for retaining the sound emitting portion in the passage.
- the invention also includes a method of forming the apparatus and a method of testing a hearing aid having a sound emitting portion that fits into the concha or ear canal of a user.
- US2008304674A discloses a hearing device test adapter provided in order to connect a hearing device output to a test microphone in a soundproof manner.
- the hearing device test adapter has an expandable first section for enclosing one section of a hearing device shell or an earmold piece in a soundproof manner such that the sound output of the hearing device shell or of the earmold piece points to the tip of the first section.
- the hearing device test adapter has an expandable second section for enclosing a section of the test microphone in a soundproof manner, with the tip of the first section directly connecting to the second section and both being connected to one another via a sound transmission.
- a behind-the-ear (BTE) hearing aid has a hearing aid housing worn behind the pinna of the user during use, and a sound tube for acoustical or electrical transmission of sound from a sound output of the hearing aid housing to an earpiece shaped for insertion into the ear canal of the user.
- the hearing aid housing may accommodate a receiver for outputting sound for acoustic transmission to the earpiece; or, the receiver may be accommodated in the earpiece in which case an electronic sound signal output by a processor in the hearing aid housing is transmitted electrically to the receiver in the earpiece inserted in the ear canal of the user during use.
- an output end of the sound tube is connected to a metal guiding member (which may comprise a 2cc coupler) in the test box that guides sound generated by the hearing aid towards the test microphone.
- the metal guiding member may be made of brass with dull chromium. The connection between the sound tube and the guiding member has to be sound proof so that sound generated by the test box does not enter the guiding member directly, and so that sound generated by the hearing aid cannot avoid entering the guiding member.
- the guiding member is provided with a metal adaptor comprising an opening substantially larger than the average output end of the sound tube in order to accommodate a wide range of output ends.
- the diameter of the opening of the adaptor may be twice the diameter of the average output end.
- the insertion of the output end of the sound tube with or without the earpiece as desired in the adaptor is achieved using a suitable wax, such as Blu tack, which is a reusable putty-like pressure-sensitive adhesive used for attaching paper items to walls.
- the adhesive material is applied to the output end of the sound tube and fixed to the adaptor around the opening when the output end of the sound tube has been inserted into the opening of the adaptor.
- the adaptor is subsequently inserted into the guiding member in a snap fit coupling.
- the hearing aid housing may also be attached to the adaptor using more of the suitable wax to fix the housing to the adaptor.
- the reference microphone is positioned adjacent the current position of the microphone of the hearing aid.
- the suitable wax is normally reused and therefore becoming contaminated by the multiple usages. This may pose a health risk to the skilled person applying the suitable wax and a health risk to the patient (or the next patient). Thus, there is also a need to provide a more sterile testing of the hearing aid. Additionally, the reuse of the suitable wax may change the transmission properties of the suitable wax. Thus, there is a further need to make testing of the hearing aid reproducible and repeatable.

- Figure 9 shows an embodiment, wherein the member 10 encloses the guiding member 52 in various side and perspective and cross-sectional views.
- the guiding member 52 is inserted into the member 10 which thereby encloses the guiding member 52 in a sound proof manner when an earpiece 116 of a hearing aid is inserted into the hole 14 of the member 10.
- 112 represents the housing
- 114 represents the sound tube
- 116 represents the earpiece
- 99 represents the hard material part of the member
- 16 represents the adhesive material surface
- 22 represents the flexible and resilient part of the member
- 80 represents the test microphone
- 81 represents a 2cc volume i.e. a 2 cubic centimetre volume of a 2cc coupler contained in the guiding member 52.
- the member 10 comprises a circumferential protrusion 924 made of the same material as the hard material part 99.
- the guiding member 52 is inserted into the member 10.
- the guiding member 52 comprises a groove 934 in which an O-ring may be contained.
- an inner surface of the circumferential protrusion 924 and the guiding member 52 may interconnect in a sound proof manner via the O-ring, when the member 10 encloses the guiding member 52.
- the protrusion 924 may comprise a circumferential ridge 934 corresponding to the O-ring above. The circumferential ridge 934 may protrude from the inner surface of the circumferential protrusion 924.
- the guiding member 52 comprises a groove matching the ridge of the protrusion 924 such that when the member 10 encloses the guiding member 52, the ridge 934 of the outer circumferential protrusion 924 and the groove of the guiding member 52 may act as a tongue and groove.
- Figure 10 shows an embodiment of the guiding member 52 of figures 2 and 3 together with the new member of figure 4 in cross-sectional view.
- 14 represents the hole in the new member 10
- 16 represents the adhesive surface
- 22 represents the flexible and resilient material part
- 99 represents the hard material part
- 81 represents the 2 cubic centimetre volume of the 2cc coupler of the guiding member 52
- 1005 represents a housing containing the test microphone 80
- 1002 represents a part of the housing 1005 containing the test microphone 80
- 1003 represents a volume/space for wires and/or cables from the microphone 80 to the test box, the connection between which is accommodated by a connector 1006, 1004 represents an O-ring providing sound proof connection between the housing 1005 containing the test microphone 80 and the test box
- 1001 represents a coupler between the two cubic centimetre volume 81 and the test microphone 80
- 1007 represents fixation means for fixing the microphone 80 to the housing 1005 such as e.g. tape and/or glue and/or a clamp.
- the O-ring 1004 may be substituted by a ridge in the housing 1005 matching a groove in the test box in a tongue and groove manner such as to ensure a sound proof connection between the housing 1005 and the test box.
