1. A hearing instrument system comprising:
- a hearing instrument having programming;
a wireless remote control configured to emit a mechanically generated acoustical pulse, wherein the programming of the hearing instrument is configured to interpret the acoustical pulse to program the hearing instrument, and wherein the programming is disabled when a calculated pulse-to-noise ratio does not exceed a predetermined threshold.

Abstract
A remote control for programming a hearing instrument includes a housing and a mechanism associated with the housing for mechanically generating an acoustical pulse for effecting control of a hearing instrument. The remote control is passive. A hearing instrument system includes a hearing instrument having a microphone and programming, and the remote control. The programming is configured to interpret the acoustical pulse generated by the mechanism to effect control of the hearing instrument.

4. A hearing instrument system comprising:
-
a hearing instrument having programming; a wireless remote control configured to emit a mechanically generated acoustical pulse, wherein the programming of the hearing instrument is configured to interpret the acoustical pulse to program the hearing instrument and the programming of the hearing instrument includes one of a decoding circuit and decoding software for interpreting the acoustical pulse generated by the remote control, with the decoding circuit or decoding software including a high pass filter for removing interfering energy, a full-wave rectifier followed by a low-pass filter for transforming the acoustical pulses into base band pulses, and programming for measuring the time spacing of the acoustical pulses to verify that the received pulses match a pulse pattern associated with a command for the hearing instrument; and further comprising programming for disabling the decoding circuit, wherein the programming for disabling the decoding circuit comprises means for calculating a pulse-to-noise ratio at the output of the low-pass filter to determine whether the pulse-to-noise ratio exceeds a predetermined threshold. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A method for controlling a hearing instrument comprising:
-
generating a remote acoustical pulse; receiving the acoustical pulse through a microphone of a hearing instrument; decoding the acoustical pulse in a program of a hearing instrument; controlling the hearing instrument based upon the decoded acoustical pulse, and disabling the decoding step based upon the calculation of a pulse-to-noise ratio and comparison of that input to a predetermined threshold in order to determine whether a false triggering has occurred. - View Dependent Claims (16, 17)

18. A method for controlling a hearing instrument comprising:
-
generating a remote acoustical pulse; receiving the acoustical pulse through a microphone of a hearing instrument; decoding the acoustical pulse in a program of a hearing instrument; controlling the hearing instrument based upon the decoded acoustical pulse, and disabling the decoding step based upon the calculation of an input and comparison of that input to a predetermined threshold in order to determine whether a false triggering has occurred. wherein the disabling the decoding step comprises determining that a false triggering has occurred, with the false triggering being determined by calculating a pulse-to-noise ratio and comparing the ratio to a predetermined threshold such that when the threshold is exceeded, the decoding step is disabled.
