在听力装置中增加电池寿命的方法
摘要：
本申请公开了在听力装置中增加电池寿命的方法，该方法包括：提供输入信号；检测输入信号中是否存在语音信号；如果在输入信号中未检测到语音信号，降低听力装置的最大功率输出，其中最大功率输出的降低随频率而变。本申请还公开了一种听力装置，包括：提供输出信号的放大器(4)；可控最大功率输出限制器(5)，配置成当来自放大器(4)的输出信号超出预定阈值时限制放大器(4)的输出信号；向可控最大功率输出限制器(5)提供控制信号(8)的语音检测器(7)，语音检测器(7)还具有用于接收输入信号的输入端；可控最大功率输出限制器(5)还配置成仅在语音检测器(7)在其接收的输入信号中未检测到语音信号存在时降低放大器(4)的最大功率输出，及最大功率输出的降低随频率而变。
摘要（英）：

The disclosure relates to a method for extending the battery lifetime in a hearing device, and to a hearing device with means for extending the battery lifetime of the hearing device. The hearing device comprise an amplifier providing an output signal and a controllable maximum power output limiter configured to limit the output signal from the amplifier when the output signal form the amplifier exceeds a predefined threshold: the hearing device further comprise a speech detector providing a control signal to the controllable maximum power output limiter, where the speech detector is further provided with an input terminal for receiving an input signal, such as the signal provided by a microphone. The controllable maximum power output limiter is further configured to reduce the maximum power output of the amplifier only when the speech detector does not detect the presence of a speech signal in the input signal received by the speech detector.
