  • Improving the safety and environmental performance of vehicles

    The European Commission proposes that all new cars from 2012 will have Electronic Stability Control (ESC) systems, to drastically improve vehicle safety. Furthermore lorries and other heavy vehicles should be fitted with Advanced Emergency Braking Systems (AEBS) and Lane Departure Warning (LDW) Systems as of 2013. Last year the Commission already proposed the obligatory fitting of passenger cars ...

  • Commission finally tackles problem of traffic noise

    Traffic noise has suddenly moved up the EU agenda, with the Commission promising to cut noise from cars, vans, buses and lorries within five years. A proposal due later this year is expected to seek to reduce car noise by four decibels and lorry noise by three. The issue of noise has lagged behind EU efforts to cut air pollutant emissions, but a recent study suggesting that the benefits of ...

  • Parallel Measurement of Air-borne and Structure-borne Noise

    With quality control or long-term monitoring of devices, machines, vehicles, etc. often several vibration and acoustic measurements are required in parallel. The FX100 Audio Analyzer is the ideal platform to quickly and easily set up such measurement systems. The FX100 Audio Analyzer is a modular system equipped with up to four parallel analysis channels.
