As of 1st July, the new European regulation (EU) N. 540/2014 imposing noise limitation for most passenger vehicles becomes effective.
For passenger vehicles types, the noise limit will be now be reduced from 74dB (A) to 72dB (A). Two more reductions are foreseen over the next 10 years up to 68dB (A).
These noise limits are likely to be extended worldwide, causing car makers everywhere to look for newer, better, innovative, more adapted testing solutions for pass-by noise that help avoid costly last-minute design changes.
Siemens PLM Software is ready for the challenge, offering LMS solutions for more effective data management and driver guidance that lead to successful pass-by noise testing.
We also offer in-house developed engineering methods to help customers meet their targets: time domain airborne source quantification analysis (ASQ) based on Transfer Path Analysis (TPA) – the most advanced technique to date.
