FIELD: acoustics.
SUBSTANCE: invention relates to acoustics, in particular, to apparatus for controlling the noise level. Noise sensor comprises a microphone, a threshold unit, and a transmitter. Introduced into the apparatus are a signal level measurement unit, the input whereof is connected with the output of the microphone, and the output is connected with the input of the threshold unit; a timer and a unit for timestamp input into the output signal, the first input whereof is connected with the output of the microphone, the second input is connected with the output of the threshold unit, and the third input is connected with the output of the timer, wherein the unit for timestamp input into the output signal is configured to supply an output signal to the input of the transmitter equipped with a memory for storing the signal to be transmitted.
EFFECT: expanded scope of operational capabilities of the apparatus and provided time-referenced control of the noise level.
