Lotus Cars recently awarded M+P international UK a contract for a pass-by-noise measurement system which is developed in association with the customer
The ever-increasing noise emission standards require the automotive designers to do complex exterior vehicle noise tests. The SO analyser pass-by-noise option efficiently supports the designers when doing their testing job by using much less equipment than traditional systems, particularly eliminating external light beam and track wire sensors.
One man - the driver - can perform the complete pass-by-noise test within the test vehicle, thus saving time and money.
The high-quality data is available for in car analysis or can be post-processed in the lab.
The Pass-by-Noise measurement system uses the complete analysis suite of M+P International's SmartOffice analyser. The integrated intelligent wizards allow quick and safe set-up and simple trigger setting.
Other features include automatic checks on entry speed and car position, continuous monitoring of wireless speed, position and acceleration as well as engine speed tacho input.
All obtained graphical results can be copied and pasted into ActiveX compliant applications such as Microsoft Word and PowerPoint where they stay active for re-scaling, changes of axis type and cursor data and much more.
These active documents are accessible from any PC platform in the network.
The comprehensive reporting tools also include a Visual Basic-compatible programming language to automate repetitive tasks, a Matlab connection and a calculator allowing to perform a number of standard mathematical operations.
The SO analyser pass-by-noise option meets requirements of ECE 51.02 and draft amendment to regulation 51, the sound level meters are in accordance with ICE 61672-1.
