- The absorption values, αp, are given per octave band.
- The absorption coefficient, αw, is based on the ISO 11654 standard which uses a rating curve which favours high frequencies. Consequently, the values are followed by an L or an M, to indicate that the PREGYBEL TM boards offer higher absorbency at low frequencies (L) or medium frequencies (M).
- The installations with mineral wool have insulation panels without a vapour barrier.
- Acoustic absorption of a non-perforated PREGYPLAC TM BA13 board:
- αw = 0,10 L (Mineral wool 80 mm plenum depth 60 cm).
