Abstract

Przedmiotem wynalazku jest mikrofon infradźwiękowy i sposób wzorcowania układu do pomiarów sygnałów infradźwiękowych. Mikrofon infradźwiękowy zawiera otwór (3) w izolatorze (2) i jest połączony na stałe z kalibratorem akustycznym (8). Kalibrator akustyczny zawiera w połączeniu od strony mikrofonu izolator (5) z otworem (6) oraz otwór (10) wyrównywania ciśnienia statycznego. Generator sygnałów elektrycznych (11) włączany zewnętrznym sygnałem zasila akustyczny pobudnik nadawczy (9), który wytwarza wewnątrz komory kalibratora (8) połączonej z komorą tylną, (4) mikrofonu ustalone ciśnienie akustyczne, działające na tylną powierzchnię membrany (1) mikrofonu. Sygnał elektryczny z wyjścia mikrofonu jest dołączony do wejścia układu pomiarowego (7).The present invention relates to an infrasound microphone and a method for calibrating a system for measuring infrasound signals. The infrasound microphone has a hole (3) in the insulator (2) and is permanently connected to the acoustic calibrator (8). The sound calibrator comprises an isolator (5) with an opening (6) and an opening (10) for static pressure equalization in connection on the microphone side. The electric signal generator (11) is switched on by an external signal and supplies the acoustic emitter (9), which produces, inside the calibrator chamber (8) connected to the rear chamber, (4) a set sound pressure, acting on the rear surface of the microphone diaphragm (1). The electric signal from the microphone output is connected to the input of the measuring circuit (7).
