■
Attention
- Measurements of sound power were undertaken in accordance with the direct method as described in
BS EN ISO 3741:2010, BS EN ISO 13141-6:2014 and BS EN ISO 5135:1999.
- Reverberation time measurements were undertaken for case radiated noise and duct noise, including
measurements of representative background noise. The data was processed to calculate casing radiated and
in-duct sound power levels in third octave bands.
- In-duct sound power levels were calculated in accordance with BS EN ISO 5135:1999.
