The level of noise of the press was over 105dB(A) Leq with the aggravating of the noise produced by the sheet metal entering under the mold.

In order to comply with the UNI / EN ISO 11688-1 standard which provides for soundproofing the collateral sound sources that could affect the residual sound

level value of the main source which is the press, we have built a sound proofing tunnel with three sliding doors suitable for freeing the front wall and

the roof in order to allow access to the bidge crane.

With the cabin completely closed we obtained a residual noise level of 80dB(A)Leq.

SGF has carried out research and development activities to develop silencers with acoustic abatement characteristics even at low frequency.

Through the use of internal modules  with low frequency resonant characteristics, SGF obtained the following result in the frequency range between 50 and 250 Hz. The improvement is evident compared to traditional dissipative silencers.
