A medical practice is normally very clinically equipped, i.e. a lot of smooth surfaces that can be easily cleaned. For this reason, a minimalistic design is necessary as well. The absence of noise-dampening and sound-absorbing materials (such as wood or fabric) is not compatible with the piercing sounds originating from a dentist’s mechanical instruments. A deafening noise and poor intelligibility between the patient and dentist are results of such a minimalistic design.
