In the latest issue of Acta Acoustica united with Acustica, Eddy Gerritsen (TNO) discusses engineering methods for the prediction of reverberation time and sound pressure levels in spaces with non-diffuse conditions. The assumptions and theoretical considerations behind the formulas in EN 12354-6 annex D are clarified. There is definitely a need for engineering models to […]

Reverberation time vs. amount of absorption in DIN 18041
German Standard DIN 18041 “Acoustical quality in small to medium-sized rooms” includes a table called “Guideline values for the free ceiling and wall surface areas to be covered with sound absorbers as a multiple of the room basic area (…)”. The table Download file presents for different room types the amount of sound absorbers to […]
