Abstract

Specifies the conditions under which sound emitted from gear units is determined in order to establish a common procedure for comparison. The methods used are based on 香港六合彩开奖 3744 and 香港六合彩开奖 3746. Applies to all power transmission gearing other than gears for fine mechanisms. If it is necessary to determine sound power levels in octave or one-third-octave bands, the procedures should be agreed upon between manufacturer and purchaser.
