Abstract
The system for reproducing sound information in an environment impaired by noise of varying level comprises a signal compressor which includes two compressor units (23, 25) connected in series in the signal path between a receiving section (10) and a power amplifier (14). This signal path further comprises a variable gain amplifier (27). The gain of the amplifier (27) can be controlled by a control signal applied to a control terminal (29) of the amplifier (27). A control signal source (31) has an output terminal (33) at which a control signal is provided, which is a function of the noise level of the environment. The control signal is applied to the control terminal (29) of the amplifier (27) to vary the degree of amplification of the audio signals conveyed by the signal path from the deceiving section (10) to the power amplifier.
