Increased noise protection

Where a level of sound insulation greater than the minimum values specified is desirable, this must be established in contracts between the contractor and the awarding authority. The following technical regulations, which are not included in planning legislation, contain relevant advice and suggestion, which require a contractual agreement to become binding.

DIN 4109 Supplement 2:

This contain instructions relating to noise levels that lie 5 dB (A) below the values given in DIN 4109/A1: 2001-01 Table 4, In accordance with Supplement 2, increased levels of sound insulation can be arranged, by agreement, to a maximum of 25 dB (A) in other areas requiring noise protection.

VDI 4100

In contract to the requirements of DIN 4109, which was adopted as noise protection level I (NPL I), this guideline contains characteristic values for two additional noise protection level - NPL II and NPL III. These two additional noise protection levels specify the arrangements for increased sound insulation

The design of residential buildings with high noise protection requirements requires the coordination of all participating contractors. The consultation of an acoustic engineer is recommended.

Noise control measures
Sources of noise in building equipment and appliances

The noise generated by plant and equipment providing services to buildings may be classified as follows:

• Noise due to filling operations

• Noise generated by control equipment

• Intake noise

• Discharge noise

• Noise due to impact or shock

Noise is generated by moving parts or by flowing media. Waste water discharge pipes are prone to vibration, particularly where water flows through downpipes, or is forced to change direction in joints and elbows (noise due to impact or shock). Experience shows that the greatest problems are typically caused by the transmission of structural noise, particularly in the area of pipe clamps and brackets or where pipe-work is run through walls or ceilings.

Building layout

An important step towards fulfilling noise protection requirements at the agreed levels is the design and production of an acoustically appropriate building layout. The following are a few - but not all - of the measures, which should be taken:

• Noise-sensitive areas should be kept as far as possible from sources of noise

• Non-sensitive areas should, wherever possible, be used as "buffer zones"

• Non-sensitive areas should not be positioned in the direct vicinity of bathrooms, toilets or stairwells.

• Potential sources of noise should be "bundled together" in the same area

The comparison of the floor plans above demonstrates how good acoustic design in the lower building example can significantly reduce the noise levels to which areas requiring noise protection are exposed.

Planning pipe installation

The installation of Wavin waste systems can significantly reduce noise levels when compared with other piping systems. When installing high-performance sound-insulating waste water piping systems such as Wavin, however, it is still necessary to consider how effectively the system can be sound-isolated. This applies to the waste water discharge system as a whole, including its points of contact with the building structure (pipe brackets and clamps, the running of pipework through walls and ceilings, mortar droppings between pipes and wall surfaces, etc.). When planning pipe installation, waste water discharge pipes should not be allowed to run inside the walls separating living areas. The attachment of waste water discharge pipes to partition walls in living areas should only be carried out under application of special noise protection measures. DIN 4109 requires that single-skin walls to which, or in which, water installations or equipment (i.e. waste water pipes) are to be attached must have an area-related mass of at least 220 kg/sq.m. Walls having an area-related mass of less than 220 kg/sq.m may only be used where prior testing has demonstrated that the walls exhibit acceptable properties with respect to the transmission of noise.


Waste water engineering to DIN 12056 and DIN 1986-100
Installation and rating of waste water removal systems

The following principles must be observed with respect to waste water removal systems:

• The system design should ensure that there are no significant pressure fluctuations which could cause the level of the trap water seal to be compromised.

• Reliable ventilation must be provided for the waste water removal system.

• A self-cleaning effect must be achieved.

• Nominal diameters should be kept to a minimum.

• Waste water must discharge at low noise levels.

Waste water removal systems

At European level, 4 different waste water removal systems have been established, which comply with DIN EN 12056-2, Section 4.2.

System I

Single downpipe with part-filled connecting pipe and a filling factor of 0.5 (mainly used in Germany where this is the only approved waste water system)


System II

Single downpipe with part-filled connecting pipe, reduced damensions and a filling factor of 0.7 (mainly used in Scandinavia)

System III

Single downpipe with fully-filled connecting pipe and a filling factor of 1.0 (mainly used in English-speaking countries)

System IV

Consists of two separate pipe systems - sewage and grey-water - (mainly used in France)

Classification of nominal diameters

In accordance with DIN EN 12056, the nominal diameter (DN) is a suitable round number, more or less equal to the (external) diameter. Each nominal diameter (DN) is allocated a minimum internal diameter, dimin (see Table 2). For the purposes of calculation, the minimum internal diameter or actual internal diameter specified by the pipe manufacturer is normally used.

Problem: Product standards for pipes and fittings are generally specified using the external diameter parameter, even though the outer diameters do not always correspond to the values given in DIN EN 12056 (see DN 100 => DA 110).
