Troubleshooting sound insulation
Buildings are constructed using many elements, and the sound insulation may be compromised by defects in materials or workmanship. Quite often, the traditional measurement will show that the sound insulation is not as good as expected or required by law. If this is the case, a measurement using sound intensity can diagnose the fault by showing the contribution of each surface element to the sound reduction index.
If you suspect a certain weak area, the contribution for that area can be measured and checked separately. Or you can divide the partition into smaller sections and check each section until you find the fault. This measurement method also eliminates flanking transmission (or, by subtraction, lets you estimate its influence), and is ideal for detecting and measuring the influence of leaks.
