Greater comfort in living, peace, quiet, and well-being is brought by the use of high-quality materials in the internal drainage system

Modern life is inherently noisy. And noise is an unwanted sound, a sound that bothers us. The term acoustic smog is aptly used in connection with noise. Experts today warn that long-term exposure to noise has a negative impact on our health – from stress and fatigue to more serious cardiovascular problems. Loud or unpleasant sounds disrupt our peace, concentration, and even our ability to communicate with our surroundings.

However, noise is no longer just a street issue. We are increasingly exposed to it inside buildings, whether at home, at work, in hotels, or schools... The government, in its regulation from 2011, stipulated that the noise level in residential rooms should not exceed 40 decibels during the day, and at night, it should be a quarter lower. For reference, 30 decibels is the level of a quiet whisper. We can easily control the volume of our speech, but what about commonplace noises, such as flushing a toilet, which can typically reach volumes of up to 75 decibels? For comparison – a washing machine usually reaches a volume of 60 decibels, a vacuum cleaner 80 decibels, and a jet engine 140 decibels.

Optimizing the sound insulation properties of spaces where we spend time deserves proper attention. It appears that using maximally efficient sound insulation in buildings, while maintaining reasonable costs, is not a trivial problem. On the contrary. Thoughtful integration of quality acoustic materials and systems into building interiors, ideally already in the design phase or during the reconstruction of the building, can significantly enhance our well-being and living comfort.

Soundproofing sewage systems is a complex issue

A standard source of everyday disruptive sounds in our lives is the technical devices installed in buildings, typically noise caused by water and waste pipes. These technical devices are particularly difficult to influence from an acoustic standpoint because the relevant sources create sound transmitted through air as well as sound propagated through bodies. Despite this, it is already possible today to prevent the decrease in quality of life in such objects through suitable noise control measures.

In the case of noise associated with the operation of internal sewage systems, we refer to generally accepted German guidelines DIN 4109 and VDI 4100, which specify permissible noise levels of 30 decibels. Soundproofed internal sewage systems, for example those from Wavin, a manufacturer and supplier of sustainable products and solutions for piping, waste, and sewage systems, easily meet these standards. This is due to the use of suitable materials based on studies examining the acoustics of residential buildings.

Optimizing the sound insulation properties of sewage apparatus is a complex problem. Its solution depends on a suitable and well-thought-out design, continues with the selection of a quality system and top materials, and culminates in ensuring the correct installation method. It's great that during the preparation of the internal sewage project, practical application Wavin SoundCheck can be utilized, which can simulate the noise level of the entire system in advance based on the parameters provided. The result of this simple operation is a detailed report containing the expected noise level, which is displayed in decibels.

Investing in low-noise piping systems pays off

A significant response to the demand for quiet sewage systems is the soundproofed pipe Wavin SiTech+. This system can significantly reduce acoustic manifestations of flowing water thanks to heavier triple-layer fittings, thereby comfortably meeting the maximum permitted noise value. The ribbed necks of SiTech+ pipes and fittings provide a firmer grip for easier installation in hard-to-reach spaces. The new pipe coloring impacts their lifespan and durability, enhances protection against UV radiation, and ensures lower sensitivity of the pipes to contamination.

The Wavin AS+ system, containing Astolan material known for its high density, also significantly contributes to noise reduction in sewage. This system includes special clamps that have been tested and designed to absorb precisely those noise frequencies that occur within the internal sewage pipes. The shaped ends of the pipes significantly reduce the pushing force required to fit the pipe end into the neck, and the self-lubricating blue seal ensures both noise elimination and very easy installation.

Quiet sewage systems guarantee incomparably greater living comfort compared to standard solutions. Although they are slightly more expensive than regular PVC sewage systems, in comparison to overall construction costs, this is almost a negligible amount. The costs of acquiring low-noise piping systems are also reduced by the easy handling of materials and an effective installation method. When you add their high durability, long lifespan, and the key advantage of soundproofed sewage, it is clear that this investment must pay off.
