摘要： Intelligibility of received speech in a radio receiver is improved by automatically adjusting audio response in accordance with ambient noise levels. When high ambient noise is present, the relative gain of the higher audio frequencies is increased at the expense of low frequency response. In this instance, some "naturalness" is traded for the higher intelligibility provided by increased high frequency gain. The ambient noise level is determined based on either a volume level or a direct sample of ambient noise by a microphone. An audio response message is built in accordance with the ambient noise level, and a digital signal processor adjusts the audio response of the radio receiver in accordance with the audio response message.
摘要翻译：通过根据环境噪声水平自动调整音频响应，提高无线电接收机中接收到的语音的可懂度。当存在高环境噪声时，较高音频的相对增益以低频响应为代价增加。在这种情况下，通过增加高频增益提供的更高的清晰度，交易了一些“自然”。环境噪声电平基于麦克风的音量或环境噪声的直接采样来确定。根据环境噪声电平构建音频响应消息，并且数字信号处理器根据音频响应消息来调整无线电接收机的音频响应。

摘要： An electrical circuit provides an output signal having a frequency representative of an input signal which has a fundamental frequency responsive to a parameter. The circuit has an amplifier (12) having an adjustable amplitude response with an input (14) coupled to the input signal and an output (16) for providing the output signal as a function of the input signal. A filter (18) is coupled to the amplifier (12) and to the output signal for at least partially determining the amplitude response of the amplifier (12). The filter (18) has an adjustable rolloff frequency characteristic. An adjustable impedance (24) is coupled to the filter (18) to adjust the amplitude response of the amplifier (12) and adjust the rolloff frequency characteristic of the filter (18) as a function of the input signal. A controller (26) is coupled to the output signal and provides a control signal for adjusting the adjustable impedance (24) and hence the amplitude response of the amplifier (12) and the rolloff frequency characteristic of the filter (18) as a function of the output signal.
