Sound Data
METHOD OF SOUND MEASUREMENT
Measurement of Sound
Data All sound data quoted has been measured in the third-octave band limited values, using
a Real Time Analyser calibrated sound intensity meter in accordance with
BS EN ISO9614 Part 1 : 1995.
All Sound Power Levels quoted are calculated from measured sound intensity according
BS EN ISO9614 Part 1 : 1995.
Semi Hemispherical Sound Pressure Levels are calculated from sound power using the semi-hemispherical
method where the noise source is in junction with 2 boundaries i.e. the floor and 1 wall.
