Abstract

Elektroniczny system przekazywania dźwięku pod ochronnik słuchu zawierający przeznaczone do integracji z ochronnikiem słuchu: układ sterowania bezprzewodowego (2), układ regulacji charakterystyki częstotliwościowej i wzmocnienia (1), mikrofony zewnętrzne (4a, 4b) dla lewej i prawej strony ochronnika słuchu mierzące hałas przed ochronnikiem słuchu i połączone z układem regulacji charakterystyki częstotliwościowej i wzmocnienia (1); mikrofony wewnętrzne (5a, 5b) dla lewej i prawej strony ochronnika słuchu mierzące hałas pod ochronnikiem słuchu i połączone z układem regulacji charakterystyki częstotliwościowej i wzmocnienia (1), wzmacniacz mocy (7a, 7b) dla lewej i prawej strony ochronnika słuchu, którego wejście jest połączone z wyjściem układu regulacji charakterystyki częstotliwościowej i wzmocnienia (1) a wyjście jest połączone z głośnikami (6a, 6b) emitującymi dźwięk pod ochronnik słuchu po lewej i prawej stronie ochronnika słuchu. System charakteryzuje się tym, że parametry pracy układu regulacji charakterystyki częstotliwościowej i wzmocnienia (1) są nastawne sygnałem nastawy przekazywanym na wejścia kontrolne układu regulacji charakterystyki częstotliwościowej i wzmocnienia (1) z układu sterowania bezprzewodowego (2), przy czym układ sterowania bezprzewodowego (2) generuje sygnał nastawy na podstawie odbieranego z zewnątrz sygnału radiowego.Electronic system for transmitting sound to the hearing protector, including: wireless control system (2), frequency response and gain adjustment system (1), external microphones (4a, 4b) for the left and right sides of the hearing protector, measuring noise in front of the protector, designed for integration with the hearing protector. hearing and connected to the frequency response and gain control system (1); internal microphones (5a, 5b) for the left and right sides of the hearing protector, measuring the noise under the hearing protector and connected to the frequency response and gain adjustment system (1), power amplifier (7a, 7b) for the left and right sides of the hearing protector, the input of which is connected to the output of the frequency response and gain control system (1) and the output is connected to speakers (6a, 6b) emitting sound under the hearing protector on the left and right side of the hearing protector. The system is characterized by the fact that the operating parameters of the frequency response and gain control system (1) are set by a setting signal transmitted to the control inputs of the frequency response and gain control system (1) from the wireless control system (2), and the wireless control system (2) generates a setting signal based on a radio signal received from outside.
