An absorption silencer is used to reduce noise and sounds in machines, systems and vehicles.
An absorption silencer works according to the absorption principle. The sound waves hit the insulating material inside and are thus absorbed. The sound energy is converted into thermal energy, which is then dissipated into the environment. This effectively reduces the sound level.
Unlike other types of mufflers, such as reflection or resonance mufflers, absorption mufflers mainly reduce mid and high frequencies generated by engines and exhaust systems. Absorption mufflers are also more effective at reducing noise in a wider range of frequencies.
Yes, absorption silencers can be customized for a variety of applications. The silencers can be customized to meet the requirements of machinery, equipment and vehicles, including aerospace, automotive, HVAC, industrial and construction equipment and many other industries.
To ensure that you are on the safe side during the test phases and also after your product has been put into operation by your customers, we use FEM calculations to determine the structural strength, fatigue strength and material efficiency of your concept, among other things, in the early development phases.
In doing so, we digitally illustrate the effects of various mechanical, thermal and electrical loads using linear and non-linear structural-mechanical calculations. The advantage of this is that we can examine the effects of the various influences on the entire product or component for any geometry, even complex ones, before we build prototypes.
The results of these calculations can be used as evidence for technical approvals, product liability and production releases.
FEM calculations of NovaNox® analytically follow the general and international standards. This ensures the reliability and comparability of the results. In detail:
We carry out sound level measurements of the sound levels LAFmax, LAFmin as well as LCpeak for you on site. The aim of the measurement is to obtain information about the sound level distribution in the frequency range from 20 to 20,000 Hz. Based on the measurement results, we determine the required power for your silencer and design a suitable structure for it.
We then calculate the insertion loss based on the planned design. If necessary, this enables us to optimize the component so that you also achieve maximum sound attenuation later in use.
We already work closely with you during the development, planning and design of the construction. Together we plan the design of the material and the manufacturing process. As a result, we achieve a result that is very close to series production already in the prototype phase. As a result, you achieve the best results and keep to your time and cost planning.
With the results of FAI, the manufacturing process is optimized for maximum efficiency and cost-effectiveness. We support you in noticeably shortening the introduction times and in successfully going into series production according to plan. This way you save your project budget and highest reliability.
We handle the entire process for you, from demand planning to logistics. We have a total of 1,200 square meters of storage space available to you as a consignment warehouse. This ensures uninterrupted production processes. This saves you costs compared to your own storage capacities and allows you to produce larger batch sizes more cost-effectively.
The supply of components for your series production is thus optimally ensured. Your absorption silencers can be delivered from the consignment warehouse on schedule and flexibly on demand. Your existing logistics processes are fully integrated. In this way, absorption silencers from NovaNox® are provided throughout the year in optimal component supply.
