Abstract

A hearing dose management device has an input, an output 6B for feeding an acoustic transducer, and an attenuating device configured to provide a controlled attenuation between the input and the output. The attenuation is dependent on past levels of the output so as to manage a hearing dose delivered by an acoustic transducer.

Abstract

A hearing dose management device has an input (2), an output (6B) for feeding an acoustic transducer (1), and an attenuating device (3) configured to provide a controlled attenuation between the input and the output. The attenuation is dependent on past levels of the output so as to manage a hearing dose delivered by an acoustic transducer (1).

Abstract

A limiter circuit (10), between an audio input (11) and a sound transducer (12), employs one or more light emitting diodes (14, 16) and resistors (R1, R2, R3) as limiting means. A limiting LED (65, 46) can be employed in a voltage multiplier circuit or an active circuit (Fig. 5). Light from the LEDs indicating the occurrence of a limiting action is visible through windows (64, Fig 6) in a housing (61) connected between leads (66, 68) extending between the signal source (11) and a headset (12).
