Sound transmits through the air. Our sense of hearing, coupled with the sense of sight, gives us the perception of space, dimensions and material. Sound has a physiological, psychological, cognitive and behavioural impact on us. Similar to the importance given to visual design, lighting and material, room acoustics also requires its due consideration. It is essential to design for the ‘ears’ and create spaces that improve our quality of life, health and well-being, social behaviour and productivity.
