<p>A hearing instrument has at least one input transducer having an input for receiving ambient signals and an output for generating a first electrical signal corresponding to the ambient signals, a programmable signal processor having at least one input for receiving and processing the electrical signal to produce a second electrical signal, a switch to switch the processor from one program to another, an output transducer having an input connected to the output of the signal processor and an output for generating an audio signal corresponding to the second electrical signal. The hearing instrument is further provided with a movement activated switch, operatively connected to the processor, including a sensor and a computer. The sensor senses head movements of the user. The computer compares the movements and validates only those which are specific to the hearing instrument. In use, a user moves his or her head in predetermined patterns. The sensor relays these movements to the computer which compares all of the movements and responds only to those specific to the hearing instrument. Once the movements have been validated and correspond to a predetermined function, the computer sends a fourth electrical signal to the signal processor to perform the function corresponding to the predetermined pattern, such as switching between one program and another, or to switch between one input transducer and another. A method for switching between one program and another or between one input transducer and another is also disclosed. The invention allows a user to take full advantage of programmable hearing instruments.</p> |
