Uncertainty in vibroacoustic investigations – research challenges

The paper formulates the need of the modification of currently applied solutions of uncertainty assessments in vibroacoustic investigations, including the ones which use the convention rules developed by 7 international metrological organisations and described in the ‘Guide to the Uncertainty’. Reservations versus currently used solutions are given in the hereby paper. It directs attention toward assumptions limiting the likelihood assessment of uncertainties of the obtained acoustic results. It draws the possible ways of the problem solutions and related to them methods. It presents the need of connecting belonging to them algorithms with not classic statistical methods, allowing taking into account departures from generally used assumptions in presently applied solutions of uncertainty estimations of acoustic investigations results. The paper presents new research trends related to the uncertainty assessment of the environment acoustic hazards control. The presented results and their conclusions can constitute the base for wider verification of the correctness of the currently applied procedures of acoustic measurements assessment and related to them estimations of errors levels of the uncertainty estimation of acoustic investigations results.
