This document is an instruction on how to use WinMLS for measuring airborne sound reduction. This document may seem long, and to get started you should only need to go through the Get started measuring airborne sound insulation section below.
It is an advantage that the reader has knowledge of the ISO 140-4:1997 and ISO 717-1:1997 since we will follow these standards. We also explain how to measure according to the new proposed standard ISO/WD 18233 that allows the use of the sine sweep (or MLS) signal to increase accuracy. This new method is better, and in cases where you have problems with not being able to get enough sound level using the tradition pink noise method, this new method may solve the problem.
