Air Inlet Silencers
The noise emissions are facing constantly stringer environmental limits. They are expressed not only in overall dBa pressure at a given distance but in terms of overall energy power and so, often within maximum frequency band perceptions.

Intermittent noise is now often an issue
Intermittent noises such as air pulses of self-cleaning filter systems must be not only be addressed but also the anti-icing ,NOx and other devices.

Expertise towards innovative solutions
The machinery intake noise keeps increasing and must be abated in ever smaller ducting sizes. The side wall flanking noises must also be controlled
