• Reverberation time of 0.5 seconds. To achieve this, a full acoustic ceiling is needed of sound absorption class A (in accordance with EN ISO 11654).

• For office and reception spaces, Building Bulletin 93 (BB93) recommends an unoccupied mid frequency (Tmf) reverberation time of <1.0 seconds be achieved. (N.B. ancillary spaces are recommendations only).
  
• Swedish Standard 02 52 68 recommends a reverberation time of 0.6 or 0.8 seconds, depending on the selected quality level. This applies to normally furnished but unoccupied rooms. The above figure is the highest recommended value for the frequency range 250 - 4,000 Hz. At 125 Hz a value 20% higher is permitted.
