Baffle silencers: THIS IS HOW INNOVATIVE NOISE PROTECTION WORKS
Baffle silencers by Scheuch COMPONENTS
This is what innovative soundproofing looks like
Ventilation systems are often the cause of high sound emissions in industrial settings. In particular, fans installed inside ducts generate sound levels that can lead to health issues for staff over the long term.
For this reason, legal soundproofing stipulations require acoustic impact to be reduced to the lowest possible minimum. Baffle silencers – which are also known as sound absorbing baffles or absorbing panels – help to drastically reduce sound pressure levels.

Baffle silencers as components in an efficient soundproofing concept
Depending on the type and source of emissions, a variety of components are used to reduce sound levels. In addition to baffle silencers, Scheuch COMPONENTS’ extensive product portfolio also includes pipe silencers and soundproofing cabinets. Which of these alternatives will have the biggest impact depends primarily on the type of system and the situation on-site. When preparing our impressive soundproofing concepts, we perform comprehensive sound measurements and analyses, which we then use as a basis for our calculations.
What are the key features of baffle silencers?
Standard Scheuch baffle silencers are available in sizes ranging from 300 x 600 x 600 mm to 3,000 x 3,000 x 3,000 mm (width x height x length). We offer variants in all dimensions at increments of 300 mm. If required, we would also be happy to produce larger special models for you.
The size a baffle silencer needs to be to achieve the best possible impact is calculated individually based on the conditions on your premises. The general rule is: the longer the silencer, the greater the soundproofing results. In contrast, the width of the duct is not a factor for the soundproofing effect.
What is a baffle silencer made up of?
A typical baffle silencer generally consists of a duct with absorber panels on the inside. Depending on the flow rate, these are equipped with a perforated plate. The absorber panels are made from mineral fibre, which is both odourless and non-ageing.
They are also covered in glass fabric, which provides protection against drips. Baffle silencers can be used at temperatures between -20 and 200 °C as standard. We also offer customers special designs for significantly higher temperature ranges.
Special designs for specific applications
In addition to our standard versions, we develop and produce baffle silencers to meet our customers’ unique requirements. These include special designs with extendable absorber panels as well as sound absorbing baffles that are extra resistant to pressure and impact. These designs meet the stringent ATEX directive on explosion protection.
For baffle silencers that will be exposed to damp gases on a daily basis, we can add an extra PTFE film to ensure the absorber’s material does not soak up any moisture.
What is more, we also manufacture silencers with inflow profiles on one or both sides, helping to reduce pressure loss. Our vertical-duct baffle silencers feature a unique design, consisting of vertical absorber panels.
Resonators enhance baffle silencer performance
To reduce emissions from particularly powerful sound sources, we combine sound absorbing baffles with resonators. These help to ensure in particular that even low-frequency sounds in the 31 to 125 Hz range are significantly reduced. Resonators are used only in conjunction with baffle silencers and are rarely used on their own.
Where are baffle silencers used?
Baffle silencers are mainly used as exhaust stack silencers for fans in ventilation systems with larger cross-sections. The sound pressure level in pipes, ducts and fans can be reduced by up to 95 percent with the help of silencers and other specific soundproofing measures.
A standard 3,000 mm baffle silencer that is combined with a suitable resonator can reduce sound emissions by up to 44 dB.
How do baffle silencers help to reduce sound emissions?
Baffle silencers absorb the sound, reducing how much sound is spread further along the duct. In this special combination, soundproofing components like these can drastically reduce the spread of sound and, as a result, significantly lower the sound load caused by fans and other components in pipe and duct systems.
We bring peace to your ducts – Scheuch COMPONENTS
The soundproofing of industrial systems is a key issue in legislation related to occupational safety and emission protection. The noises generated by fans and other components in ducts and pipe systems are responsible for a large portion of the sound emitted by production plants. With our innovative baffle silencers – which can also be tailored to your individual needs – we help you to comply with legal requirements and also look after your employees’ health effectively. If you would like to find out more about baffle silencers or soundproofing in general, we would be happy to answer your questions at any time.
