A method for limiting the sound volume in an earphone, a headset (8), or the like, to a maximum permitted level, entails that an input signal (2) is sensed by a processor (4) and damped by a damper (6) if it is excessively high. Thereafter, the signal (7) is transmitted to the earphone, the headset (8), or the like. The processor (4) switches between an active mode and a rest mode. An apparatus for limiting the sound volume according to the method includes a microprocessor (4) and a damper (6). |
