Abstract (en)
[origin: WO0002418A1] The hearing instrument comprises a circuit (12) for transforming an audio signal (11) into an output signal (13), which circuit (12) comprises filter means (18) for dividing the audio signal (11) into at least two frequency band signals and amplifier means (20, 22) for amplifying the frequency band signals. The circuit (12) further comprises control means (24) for the generation of at least first (21) and second (23) control signals which control the amplification of the frequency band signals and means (26) for including the amplified frequency band signals into the output signal (13). The control means (24) are embodied so as to increase a level of the first control signal (21) while simultaneously decreasing the level of the second control signal (23), or vice versa. The control means (24) may comprise a single control element (38), e.g. a variable resistor. In this way, the hearing instrument can easily be configured as a BILL or as a TILL or as a substantially linear hearing instrument.
