A tutorial on sizing calculations for reactive silencers to reduce duct and piping noise (SILDIS® software: a quarter of one hour)
- Details
To reduce noise in ducts and piping, the SILDIS Module 1B software enables the sizing of reactive silencers as illustrated by a tutorial covering the case of a simple expansion chamber tuned to optimize noise reduction performance.
Applications include, in particular, noise control for pressurized fluid systems (e.g. those involving a compressor) and the reduction of exhaust noise from internal combustion engines.
In general, the SILDIS Module 1B software (in Excel format) allows for the...
Modeling noise emissions from buildings and other constructions with SILDIS software: a tutorial (8 minutes)
- Details
The SILDIS software (in Excel format) enables the modeling of sound emissions from buildings and other constructions as illustrated by a tutorial concerning a heterogeneous façade (i.e. one with elements differing in nature and, consequently, in acoustic performance - sound reduction and/or directivity -) to determine (and compare against targeted values):
- the sound power level (in dB ref. 1 pW):
- of each element, considered individually
- total, for the façade
- the sound pressure level...
Now, the modules of the ITS acoustic calculation software, SILDIS, in Excel format, are with a near-perpetual license (100 years).

Now, the modules of the ITS acoustic calculation software, SILDIS, in Excel format, are with a near-perpetual license (100 years). They allow the prediction of the acoustic performance of cosntruction systems designed for sound absorption/attenuation, and of the impact of sound sources (by modeling sound propagation) for various applications in the field of soundproofing (building and industry):
- Prediction of the acoustic and aerodynamic performance of dissipative or resonant silencers...
