Title Noise reduction by selection of machines with low sound emission - Pneumatic hammers and drilling machines
Original title Lärmminderung durch Auswahl leiser Maschinen - Druckluftbohrhämmer und -hammerbohrmaschinen [in German]
Bibliographic information Jan. 1990, Vol.1, p.7-8. Illus.
Abstract Pneumatic hammer drills are used in underground mining and in civil engineering for tunnel construction. The noise levels of 117dB(A) for machines up to 30kg - and 120dB(A) - up to 200kg - were determined to be maximum permissible sound levels. No newly purchased machines should have sound power levels above these values.
