We perform measurements of engine noise and vibrations and the engine dyno. We have performed several dozen such measurements at various locations on the engine: both on the block, sub-systems, turbine and exhaust. We always measure the engine speed at the same time, which is necessary, for example, for Order analysis.
We have assessed the test cells for compliance with the ISO 3746 standard for the determination of sound power by the pressure method. The cells intended for acoustic tests have been adapted accordingly and the K2 correction is sufficiently low.
If this is not enough, we can also precisely determine the acoustic power of the engine at constant speeds using an intensity probe.
Measurement results can be elaborated in the form of various graphs, but we can also provide raw data as .uff, .txt, .wav files, and in other formats.
