These measurements meet the requirements of ISO 354. All measurements were carried out on standard tiles with acoustic tissue laminated on the back.
The construction height specifies the distance between the undersides of the suspended ceiling and the existing construction.
The tiles' sound absorption is affected by the construction height and by any mineral wool behind them.
