Title Noise emission and reduction by drop forging shops
Original title Geräuschemission und Lärmminderung von Gesenkschmieden [in German]
Bibliographic information Feb. 1988, Vol.108, No.4, p.179-184. Illus. 8 ref.
Abstract Sound pressure levels in drop forging shops with one or more drop hammers and different extents of sound insulation (walls, doors, ceilings, ventilation ducts) were determined. The data were used to calculate noise levels inside and outside the drop forging shops. A distance of 25m is required for the noise emitted by small and new forges with extensive sound insulation to drop to 46dB(A). For large forges a distance of 50m is necessary.
