  2. BOUWFYSICAGELUID Jos de Wit & Mark van Delst

  3. Intro Akoestiek Nagalmtijd Berekening Opgave

  4. Akoestiek Wat is dat nu? Waarom aanpassen?

  5. Nagalmtijd Wat is dat nu? Wat kun je ermee?

  6. Berekening Formule: T= (1/6) x (V/A) T = nagalmtijd in seconden V = volume van de betreffende ruimte A = aanwezige geluidsabsorptie in m2 (o.r.) A = (a1 x S1) + (a2 x S2) a = absorptiecoëfficiënt van het materiaal S = oppervlakte van de constructie in m2

  7. Opgave Afmeting ruimte: 4 x 7 x 2,7m Plafond: 28m2 a = 0,76 (1000Hz) Vloer: 28m2 a = 0,03 (1000Hz) Pleisterwerk: 43,4m a = 0,02 (1000Hz) Glas: 16m2 a= 0,02 (1000Hz)
