Prior to the acoustic zoning carried out by the town council of Colle Val d’Elsa, PRESSO FONDERIE had on two occasions measured the noise emitted to the outside atmosphere and proved to comply with regulation parameters. The subsequent zoning of January 2005 (Colle Val d’Elsa council resolution no. 5 dated 20/01/2005) reviewed the limits and lowered them considerably.
We promptly prepared to meet the new regulation by building a wall of sheet metal panels filled with sound-deadening material near the furnace suction motors and dies of the die-casting department. This wall, designed especially on the basis of the characteristics (frequency and intensity) of the noise to be reduced has made it possible to achieve a reduction below the limits set by the council ruling (65 db by day and 55 db by night).

A further intervention of soundproofing has been the insulation of the terminal part of the existing chimneys emission.
During 2018 after all the changes mde on foundry department we have done new phonometric controls that, as for those oh 2016, have confirm the fully respect of the noise emission limits both in daytime and during the night
