Cooking and washing up are noisy activities. In addition to the sound produced by staff, there is also the noise from catering machinery and extractor fans.

  • Hard surface materials create problematic sound amplification and sound propagation. The sound is transported a long way and so disturbs a large number of people.
  • Hard flooring creates noisy footsteps.
Ecophon's suggestion
  • 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).
Building codes and standards
  • For kitchens, Building Bulletin 93 (BB93) recommends an unoccupied mid frequency (Tmf) reverberation of <1.5 seconds be achieved (N.B. ancillary spaces are recommendations only).
  • Swedish Standard 02 52 68 recommends a reverberation time of 0.5 or 0.6 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.
  • In view of hygiene requirements, the acoustic ceiling must not attract dirt and must be washable.


Indoor climate

  • The acoustic ceiling must tolerate relatively high levels of humidity.
