Sound Insulation

Modern hygienic, convenience demands for living and working areas, include good acoustic environment.
In a room with good acoustics the required sound is emphasised, while unwanted sounds are eliminated or reduced sufficiently so as not to cause disturbance. Good acoustic environment includes the effects of noise both within spaces and its passage between adjacent spaces.
Sound insulation or sound reduction, relates to the overall ability of a building structure to prevent sound from passing between adjacent rooms and should not be confused with sound absorption which is the property of a material which permits sound waves to be absorbed, thus reducing the sound level and eliminating echoes or reverberations within the room that has been installed.
An increase in the sound absorption within a space does not necessarily mean a corresponding increase in the sound insulation between adjacent spaces. There is no single direct link between absorption and insulation. Other additional factors contribute to effective sound insulation.
Two types of sound insulation might be referred to :


Airborne sound insulation : Is the ability of a structure to reduce airborne sound energy that would otherwise be transmitted to adjacent spaces. Insulation against sounds e.g voices, music, vehicle traffic, noice from mechanical or elecrtronic equipements etc. The ideal materials for good airborne sound insulation must have a very high mass and low stiffness. For airborne sound insulation all openings (doors, windows) as well as holes, ductwork, piping and electrical penetrations, ventilation units etc. are very important, since sound will be transmitted through any opening with little loss. It should be noted that the overall airborne sound insulation of a construction is usually closer to that of the 'weaker' element.
Impact (structure-borne) sound insulation : Relates to the reduction of noise originating from the above floor, e.g. footsteps, furniture movements, falling objects, drilling and hammering of structure, etc.
Insulation against structure-borne (or impact) noise can be achieved by the use of :
- Soft floor finishing (e.g. carpet, cork, vinyl, rubber, etc)
- Resiliently suspended ceiling installation
- Antivibration mounts
- Floating floor construction (with separating layer of cork boards, extruded or expanded polyethylene sheets etc.)


There are many special products or combination of products that are used for sound and vibration treatment of constructions, like acoustic suspending ceilings, acoustic boards, acoustic wall linings, products having the combination of sound absorption ans sound insulation for roofs, walls, partitions and floors and antivibration products.


In this section the following products are examined :

  • Floor sound insulation products
  • Sound absorption/insulation products for residential and industrial applications
  • Antivibration products

There are sound absorption/insulation products that are examined in other sections (e.g. fibre products in thermal insulation products, fibre and perforated gypsumboard tiles in suspending ceilings etc.)
