Soundproofing for a successful neighbourhood.
Soundproofing against noise from the environment or against noise from within a building is gaining increasing importance for quality of life. Good sound insulation values are easily attained in timber structures. However, the prerequisite is careful planning and installation of the building measures.
Wooden construction and footstep noise insulation
Footstep noise is structure-borne sound caused by e.g. walking, the movement of chairs or impact. There is a large number of certified ceiling structures available in order to achieve prescribed soundproofing values (e.g. in accordance with DIN 4109). It is important to know that regulations relating to footstep noise insulation
that are effective for solid building structures do not apply to timber construction.
Ceilings with visible wooden beams require different measures than those used for suspended ceilings using plasterboard or fibre-reinforced plasterboard. However, the guiding principle is always to use isolated materials.
Computer-assisted soundproofing forecast
If a ceiling made from wood meets the requirements of footstep noise insulation it generally also meets the requirements for airborne noise protection. A computer-assisted soundproofing forecast such as the one provided by Peter Müller GmbH is a valuable decision aid that will guard against unwelcome surprises. Careful on-site implementation is the prerequisite for the effectiveness of the planned measures.
Incidentally, for Peter Müller GmbH the avoidance of footstep noise and vibration problems starts with the structural calculations for the ceiling beams, since the annoying low frequency vibrations of a wooden beam ceiling do not begin until sagging of 6 mm is reached. Designing the ceiling beams to meet this criterion solves the problem before it occurs.
Soundproofing for interior and exterior walls
Peace ..... at last
In contrast to conventional methods of solid construction, timber construction makes use of the principles of multiple layers. Certified construction systems ensure that the requirements are easily met while slight modifications increase soundproofing to what may be required for severe levels of outside noise (a busy road, airport flight paths etc.).
Interior walls between rooms or between flats using a number of inspected constructions can also provide the desired soundproofing. The principles of multiple layers are also used here to good effect together with planking of varying bending stiffness. What is decisive here, besides careful planning of the joints, is precise installation since it is well known that airborne noise gets through the smallest crack.
