MONITORING REDUCING METHOD OF NOISE/VIBRATION AND NOISE/ VIBRATION MONITORING DEVICE THEREFOR

Title:

MONITORING REDUCING METHOD OF NOISE/VIBRATION AND NOISE/ VIBRATION MONITORING DEVICE THEREFOR

Document Type and Number:

Japanese Patent JP2003083803

Kind Code:

A

Abstract:

To monitor a noise and/or vibration within a control value and to reduce it quickly on a construction site.

Noise meters 1A and vibration meters 1B are arranged on three or more spots in the construction site or in the range including its periphery. The noise meters 1A and the vibration meters 1B are connected to a computer 2, to thereby acquire noise and/or vibration data measured by each noise meter 1A and vibration meter 1B, and to compare the data with the control values of the noise and/or vibration. When measured noise and/or measured vibration levels become higher than levels requiring warning based on the control values, the noise and/or vibration generation position is specified based on each measured noise and/or measured vibration data, and the warning that the noise and/or vibration are higher than the prescribed levels is issued to the inside of the construction site or to specific workers.
