ABSTRACT:
A device is provided for reducing noise in the human ear having a microphone which picks up the noise and a reproduction transducer to which a noise compensation signal is fed via a compensation circuit which is connected with the microphone. The microphone in the device has a balancing element which is arranged in front of the sound entrance opening of the microphone. The balancing element defines a quasi-constant sound reflection and accordingly reduces individual reflection effects caused by the fundamental diversity of the external region of the human ear and improves the use of the entire device and increases the effectiveness of the noise compensation overall. In this way, headphones/hearing protectors can also be designed as acoustically closed systems which are designed so as to rest on the ear.
