Title Advanced sound attenuation: a valve against noise - Howling, noisy abrasive-wheel cutting-off machines are out
Original title Schrittmachende Schalldämpferkonstruktion: ein Ventil gegen den Lärm - Heulende, laute Schruppschleifer sind passé [in German]
Bibliographic information 1990, No.2, p.26-27. Illus.
Abstract The operating principle of a pressure-regulating valve installed in an abrasive-wheel cutting-off machine is illustrated. It reduces the sound level of 1.2-3.8kW pneumatic grinders at idle to below 80dB(A) and during operation to below 90dB(A).
