Method for assessment of the noise exposure level and indicator of the noise exposure level

摘要

how to evaluate the level of exposure to noise of measuring sound pressure at the site of the noise pollution, is characterized by the fact that simultaneously with the measurement of acoustic signal and in the same place, by the vibration sensor (2) acting a measuring system (1), the sound pressure is measured by the vibration.subsequently, by mikrokontrolera (3) converts the impact vibration affecting the signal measuring system (1) and generates signals indicative. these signals are sent by radio to the parent unit link.in the situation where the limit values are exceeded the level of noise exposure activates the warning signal indicator (5) situated in place and / or beyond the assessment of exposure to noise. the level of exposure to noise on basis of common mechanical measuring system (1) sound pressure sensor mounted on the vibration (2).both of these devices are connected to mikrokontrolerem (3), and a microcontroller with sygnalizatorem (5). a microcontroller (3) is connected by a radio link from the parent undertaking. a microcontroller (3) may be located on a common basis of mechanical measuring system (1), the sound pressure and vibration sensor (2).
