It is possible to optimise the acoustical environment with the thoughtful selection of materials? The choice of materials that have the capacity to reduce sound reverberation inside the room, those which limit the transmission of noise from outside the room, and those which minimise background noise from heating, cooling, and ventilation systems are most suitable.
Structure-borne noise, also known as impact noise, is produced when sound arises from the actual impact of an object on a building element such as a wall, floor or ceiling. Energy passes through the structure and creates noise in nearby rooms. Examples are heavy footsteps particularly on bare timber or tile floors, banging doors, scraping furniture, vibrations from loud music and plumbing noises. The Impact Insulation Class or IIC is used to rate the impact of noise insulation of floors. This can often be the hardest noise to isolate.
