Title Noise reduction by selection of quiet machines - Pneumatic hammers
Original title Lärmminderung durch Auswahl leiser Maschinen - Drucklufthämmer [in German]
Bibliographic information Apr. 1989, No.2, p.8-10. Illus.
Abstract On the basis of existing directives (VDI 3749 Part 2 and EC-guidelines), sound pressure levels of 108, 111 and 114dB (for weights of up to 20kg, 20-35kg and over 35kg) were determined to characterise pneumatic hammers with the lowest noise emission. For selecting quiet pneumatic hammers, A-weighted sound pressure levels according to DIN 45649 Part 1 or 2 and sound levels determined under operating conditions according to DIN 45635 Part 20 should be compared with the above values.
