Integration of the sizing of silencers made of discontinued splitters (baffles) to the simulation software SILDIS^®

Published: 12 May 2015

Rectangular silencers with splitters (baffles) are the basis for many applications related to soundproofing when it is desired to limit the propagation of noise through openings with a circulating fluid. In many common cases (e.g. air conditioning networks, ventilation of equipment premises or of other rooms, ventilation systems for enclosures), splitters are most of the time continuous, i.e. with a height equal to that of the duct in which they are inserted, which facilitates their attachment...

Published: 15 September 2014

Predicting sound decay in enclosed spaces remains a topical subject in Research and Development in acoustics.

Enclosed spaces are often an object of study in terms of acoustics when it comes to designing a soundproofing industrial building, an enclosure for a machine/ a process of big size, a test bench, a local for technical equipment or a room intended to house activities such as catering, education, sports and recreation (generally: whenever it is appropriate to consider the impact of...

Integration of the prediction of the acoustic performance of nozzles to the simulation software SILDIS^®

Published: 11 February 2014

Nozzles ^[1] are components which are often present in duct systems such as those to be envisaged for air conditioning systems, ventilation systems for premises or for enclosures (in general: each time the installation of a fan is to be envisaged), exhaust lines for thermal engines or gas turbines, etc ...

The acoustic performance of nozzles must be accounted for the purpose of the design of equipments for which noise transmission at extremities of the duct systems must be limited, being a...
