Noise source ranking and problem diagnosis
The loudest machine at close range is not necessarily the main contributor where a problem occurs. We establish the significance of individual sources at relevant receivers and rank their contributions and improvement potential, helping you choose a justified direction for corrective action.
Focus on the sources that matter most at the receiver
A useful ranking connects each source to the location where its impact is assessed. We define the problem, relevant receivers and operating conditions, then review available measurements, inventories and models. The review checks whether the information represents a consistent operating situation and whether contributions from sources running simultaneously can reasonably be distinguished.
We examine source contributions in relation to their characteristics, locations and sound propagation paths. Where additional evidence is needed, we identify useful observations or comparisons between operating states. Findings are organised for specific receivers, rather than producing a machine list ordered only by the sound level measured directly beside each item of equipment.
A source's importance may change between receivers and operating scenarios. We explain these dependencies and the strength of the supporting evidence instead of presenting a supposedly universal order. Recommendations identify sources for further assessment or reduction planning; the diagnosis itself is neither a noise control design nor confirmation of the performance of future measures.

What you receive
You receive a source ranking with recommendations, the reasoning behind the order and the conditions to which the assessment applies. It identifies where action could make the greatest difference to the problem and where better information is needed, supporting informed planning of subsequent assessments and noise reduction priorities.
