| 摘要 |
The invention relates to a communication system for noisy environments comprising a communication device, at least one sound device comprising sound transmitting means and sound receiving means, sound detecting means for detecting one or more detecting signals in the proximity of said sound transmitting means, and a noise-controlling device comprising a first device for internal signal noise control connected to said communication device or said sound device and a second device for external signal noise control connected to said communication device or said sound device and said sound detecting means, where at least one connection connects said first device for internal signal noise control and said second external signal noise control connected to said communication device, where said noise-controlling device receives one or more signals from said communication device or said sound device, and transmits the noise-controlled form of said one or more signals to said communication device or said sound device. <IMAGE> |
