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.
