25 years ago optically transparent sound absorbers made of micro-perforated sheets were introduced. Over the last yeas various applications and developments have been conducted. Optically transparent as well as translucent, coloured and printed sheets have been introduced. Other functions such as heating and cooling have been added into a stretched ceiling as well as modular systems. Sound absorption data according to ISO 354 for different set-ups are presented. pplications in various spaces will be presented and discussed. Day-light ceilings, mirror ceilings as well as absorbers in front of glass will be shown. Finally, some case studies will be discussed.
