We recommend a reverberation time of 0.5 seconds for small premises and 1.5 seconds for the large ones at frequencies between 250 – 4000 Hz.
A low background noise level is important for hearing-impaired customers. Other installations, such as electricity and sprinkler systems, have to fit into the acoustic ceiling.
Install acoustic slabs along the entire ceiling surface. There is usually more noise next to service and checkout desks, so they need more attention in the design phase.
