MPL Helps to Reduce Airport Noise Levels

Abstract

WITH a low noise level of less than 59dBa at one metre, the 400Hz ground power systems from MPL Power Systems plc are said to be ideal for operation in noise conscious environments such as airports. For use as decentralised or centralised units they accommodate a wide range of aircraft types and claim several advantages over conventional mobile units. Developed from the MPL TQ range of 400Hz silenced frequency converters which are used in well over 30% of large data processing mainframe sites throughout the UK, they offer an output noise which is so low that, if necessary, units can even be unobtrusively installed in passenger areas.
