为了保护生活环境和顺利进行施工建设,日本建设省于1983年10月1日起开始实施“低噪声型、低振动型建筑机械规定要领”。这里摘译的是低噪声型建筑机械的噪声标准和测定条件。一、低噪声的基准值是以下述三个基本条件确定的 1.低噪声型建筑机械的噪声值应比标准型建筑机械的噪声降低dB(A)以上; In order to protect the living environment and smoothly carry out the construction, the Ministry of Construction of Japan began implementing the “requirements for low-noise and low-vibration construction machinery” on October 1, 1983. Excerpted here is the noise standard and measurement conditions for low noise construction machinery. First, the low-noise reference value is determined by the following three basic conditions: 1. The noise figure of a low-noise construction machine should be lower than that of a standard construction machine by more than dB(A);
