Sound Insulation Measurement With The New SLM HBK 2255 And The Building Acoustic Partner App

Manually-scanned level measurements are becoming increasingly popular for level measurements in field sound insulation surveys. Compared to measurements at fixed microphone positions, manually-scanning reduces the number of separate microphone positions required for a sound insulation survey and typically reduces the total survey time. It also eliminates the need to carry a tripod for the sound level meter. There is even evidence that manually-scanned measurements are more repeatable than measurements at fixed positions*, particularly at low frequencies.
