Method and apparatus for the remote control of a hearing aid means
First Claim
1. A method for remote control of a hearing aid circuit, comprising the steps of:
- providing control pulses formed by sound waves and having long and short pulse durations;
evaluating the pulses in accordance with their pulse duration such that a respective evaluation time is allocated to pulse starts; and
providing a chronological spacing of said evaluation times from a respective corresponding pulse start shorter than the long pulse duration and longer than a sum of the short pulse duration and a time by which the short pulse duration can be lengthened by a received reflection of the sound waves.

Abstract
According to a remote control method, sound waves are output by a transmitter as short and long remote control pulses. These pulses are evaluated according to their duration. In order to largely avoid disturbances in the evaluation due to superimposition with reflected remote control signals, defined parameters, particularly at least one evaluation time of the remote control method, are adapted to variations in the duration of the remote control pulses output by the transmitter which are possible due to superimposition. Furthermore, a blanking is proposed which has a variable blanking duration that automatically adapts to a pause duration between two remote control pulses, which is varied due to a reflection.

8. A method for remote control of a hearing-aid circuit, comprising the steps of:
-
providing control pulses formed by sound waves which are not reflected and which have long and short pulse durations, and wherein reflections of the sound waves can also be present whose pulses are mixed in with pulses of the unreflected sound waves; evaluating the pulses according to their durations; blanking pulses of the reflected sound waves appearing after an end of a short pulse duration control pulse with blanking pulses that have a blanking time of variable duration; and automatically adapting the blanking time to a duration of a pause which remains between an end of a control pulse which is lengthened by reflection and a start of a following control pulse. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
