Abstract
An apparatus and method are provided for monitoring magnetic hearing systems by receiving a magnetic hearing system in an acoustic hearing aid testing device and then detecting the magnetic field output by the magnetic hearing system with a magnetic-to-acoustic testing device when the magnetic hearing system is being tested by the acoustic hearing aid testing device. The magnetic-to-acoustic testing device then develops an acoustic output signal representative of the detected magnetic field which may then be used in traditional acoustic monitoring techniques, such as performing a listening check of the magnetic hearing aid system or performing standard ANSI types of measurements, by the audiologist or tester.
Claims3
Test apparatus for a magnetic drive hearing device, including a drive coil for diving an ear lens magnet removably affixed to the ear drum of a wearer, the test apparatus comprising:
- an acoustic chamber;
- a stand for mounting the drive coil in the vicinity of the acoustic chamber;
- and
- a magnetic-to-acoustic converer situated in proximity to the driving coil.
