Abstract
A headset-based hearing tester and hearing aid programming instrument featuring an electronic module shaped as a headband having a connected acoustic transducer module. The electronic module includes microcontroller, internal and plug-in external memory for storage of program code and patient data. The headset instrument in conjunction with a hand-held patient response device is capable of automatic hearing testing. The produced audio stimuli including test tones, speech and verbal instructions are retrieved from external memory cards. The instrument automatically computes fitting parameters and is capable of programming a programmable hearing aid via a port for direct wire programming or via wireless methods including inductive coil coupling to a hearing aid equipped with a receiving coil.
Claims19
A hearing tester comprising,
- a headband shaped electronic module with circuitry configured as a self-contained audiometer, with audiometer circuitry having means for producing electrical signals representing sound stimuli and means for recording a sequence of patient responses,
- acoustic transducer means mechanically connected to the electronic module for receiving said electrical signals and producing said sequence of sound stimuli, and
- a patient input signaling means connected to the audiometer for transmitting a sequence of patient responses to the audiometer.
A hearing tester and hearing aid programmer comprising,
- a headband shaped electronic module having a microcontroller, an internal memory and a main memory, the main memory being a data card having stored digital test stimuli, and means for converting said stored digital test stimuli to audio signals,
- sound transducer means supported by the electronic module and electrically connected to said electronic module,
- a patient operated signaling means communicating with said electronic module to respond to a hearing test procedure,
- a hearing aid fitting computation program operating on data from said patient operated signaling means to produce hearing aid programming data, and
- short range transmitting means for transmitting the hearing aid programming data to a receiver associated with a programmable hearing aid.
A method of testing hearing of a patient and programming a hearing aid comprising,
- testing a patient with audio stimuli from an acoustic transducer and microcontroller worn by the patient,
- recording patient responses to the stimuli using said microcontroller to control recording of responses,
- transforming said responses to programmable hearing aid input data using said microcontroller, and
- transmitting said hearing aid input data over a distance of less than 20 centimeters from the vicinity of the microcontroller to the programmable hearing aid.
