METHOD AND SYSTEM FOR AUTOMATED MONITORING OF THE EQUIVALENT SOUND LEVEL Russian patent published in 2022 - IPC G01H17/00 

FIELD: measuring.

SUBSTANCE: invention relates to the field of metrology, in particular, to means of measuring noise. Method includes selecting a point characteristic by noise level; obtaining data by means of at least three noise meters distanced from each other by no more than 3 values of the sound wavelength at frequency of 1,000 Hz in an aerial environment under normal conditions at a given time pitch; transmitting telemetry data packets marked with time reference tags; obtaining an equivalent sound level at each stage, analysing and storing the data. The system comprises noise meters placed as described above on a support rack; wherein each noise meter includes a microphone linked with a digital processing unit configured to ensure the marking of telemetry data packets with time reference tags, and a data interface to an external computer network and the Internet; the outputs of the digital processing units are linked with the inputs of the data transmission tool linked with a data processing and storage tool via cable or wireless connection, wherein said data processing and storage tool constitutes a computer equipped with a software tool for calculating the equivalent sound level.

EFFECT: expanded range of technical means of automated monitoring of the equivalent sound level, ensuring full time coverage of the process characteristics of operation of a "noise-producing object", reliability, and monitoring cost reduction.
