Acoustic silencers

The mufflers are elements that are inserted in the conduits where a gas flows. Their job is to reduce as much as possible the transmitted of noise.
A muffler must be chosen using the following criteria of selection.

1. The sound transmission loss must be the major possible one, not only worldwide, but also spectrally.

2. Depending on the speed of the gas, there will be demanded a few aerodynamic special conditions.

3. The materials that compose the muffler will come determined by the temperature and the pressure of the gas. The permanence of the set will depend on the quality of the selected material.

4. The geometry and dimensions of the muffler will come determined in every case for the available space, the wealth and the loss of load. There are situations in which the volume is very limited, for example in case of the leaks of compressed air.

Rectangular Silencers

These have a coating of absorbent material on the inside that gives them their functional properties.

There are various models, each suited to specific applications.

Circular Silencers

The main feature of reactive silencers is their dependence on geometric shapes. They can have one or more chambers, dampers, resonators, etc.
