Operating theatre

The work environment along with the hygienic requirements in the operating theatre and connecting areas are key points for the design. Conducting a surgical operation is a team effort underpinned by communication between the team members. The operating theatre and the supporting areas must continuously be supervised from a hygienic point of view. An acoustic ceiling has to fulfil many demands to be an alternative in these environments.

  • The acoustic environment becomes a challenge due to the type of surface materials genrally used in operating theatres. Easy to clean hard surfaces are used for floors and walls to ensure a high level of hygiene.
  • Noisy equipment along with the density of people in a small space makes it important to consider the acoustic design of the room.
Ecophon's suggestion
  • Reverberation time 0.5 s or less. Highest value 250 - 4000 Hz. 125 Hz: 20% higher value permitted. Corresponds to 90% of floor surface covered with Absorption Class A (according to EN ISO 11654).
  • Acoustic ceilings need to be chosen with particle emissions in mind. Ceiling systems should be documented how they perform in terms of emission of particles.
  • The types of cleaning routines and cleaning or disinfecting agents used, needs to be considered when choosing the acoustic ceiling.
Product recommendation
  • Ecophon Hygiene offers a robust acoustic ceiling practically developed for controlled environments. Close to zero emissions and resilient to bacterial growth makes it a strong candidate for the most challenging healthcare environments.


A well planned sound environment improves peoples ability to perform. Understanding of acoustics enables you to define the relevant descriptors to get the best end-result.

Indoor climate

The indoor environment has a major impact on people’s health. The building materials, the ventilation, the furnishing, the cleaning routines and the activities are factors that all influence the indoor climate.
