Sound pressure levels dB(A) at 3m distance are for a single air curtain mounted at its maximum mounting height, operating in
a room with average acoustic characteristics as defined in CIBSE Guide B5 (reverberation time 0.7s at 1kHz) and a room size
equivalent to 8 air changes per hour (ac/h). Care needs to be taken when selecting air curtains for an installation as noise
levels can be several dB higher if the mounting height is reduced, if the room is more ‘live’ (i.e. hard surfaces, no furnishings or
absorbent materials), if the room is smaller than 8 ac/h equivalent or a combination of these factors. Noise levels will also
increase if more than one air curtain is installed at the same doorway (e.g. +3dB(A) for 2 equal point sources: direct field).
