Our ear constantly provides us with information regarding the volume and colour of sound as well as time that it takes to reach us. Our brain transforms these stimuli into valid information and tells us, where a noise comes from, who or what produces it and what we should do with this information.

Furthermore, we are highly able to block out undesired noise, disturbing sounds or signals, annoying background noises, speech noise or reverberations. When concentrating on our core activity, we can simply “switch off” these types of stimulations, but this process costs us a lot of energy.

• Bad acoustics deform the sounds we want to hear.
• Reverberations fill the breaks in between the individual spoken words which leads to a decline in the speech intelligibility.
• Several sound sources fill a room faster, and noise of up to 10 dB is produced
• A high level of background noise masks the message
• The sound is not sufficiently damped over a distance, so that other sounds and speech noise have too much impact on the listener
• There is no need to explain that employees, as a consequence, are not able to work with full concentration, perform less, make more mistakes and are more tired at the end of the work day.



A quiet room results in healthier employees who can concentrate better, are less stressed and have enough energy left at the end of the work day to be able to enjoy a relaxing evening at home.
