“…Research on subjective sound characteristics relate to the description and interpretation of auditory impressions. The results confirm that noise perception is significantly affected by among others psychoacoustic aspects of sound, signal time structure, shaping of subjective sound features in the domain of: time, frequency, time-frequency [8,17,18,19]. The undertaken research on the assessment of the quality of audio signals is based on the use of two categories of methods [26]:…”

The article proposes an original way of modeling vibroacoustic phenomena of exploited machines/devices using the method of audio parameterization. This method extends the current approach to this type of research and consists in taking into account the psychoacoustic effects associated with the emission of vibroacoustic energy. The proposed solution is based on the determination of mel-cepstral coefficients of the examined signal and its classification, due to the impact of noise. It was presented verification of the method on the example of studies on the impact of road noise sources.

“…The dynamic and continuous nature of the machine operation influences the choice of its observation. Based on the assessment of the variability features of the machine, it is possible to infer not only the variability of its technical condition but also that of its interaction with the environment [24]. In the assessment of machines with the use of the OEE model, there are considered long-term input data sets continuous in time, which in many cases do not reflect the specifics of real production processes and, above all, real exploitation processes.…”

This article presents a new approach to the exploitation assessment of machines and devices. A key aspect of this approach is the construction of the assessment model based on the geometric representation of measures associated with each other, which covers the full specifics of the exploitation process. This approach is successfully implemented by the Overall Equipment Effectiveness (OEE) model, which is fully susceptible to the geometric modelling process due to the three-way system of assessed exploitation aspects. The result of this approach is the vectored OEE model and its interpretation in terms of time series of changes in values of components. Methods of determining vector calculus measures were developed, including the second-order tensor and gradient. This is the subject of the variability of the reliability conditions of machines or production processes. It allows for the realisation of an exploitation assessment based on dynamic changes in the values of their components in the time domain. This is a significant difference to the classical static approach to such an assessment. The developed new geometric OEE model was confirmed by verification tests using the LabView software, based on two parallel data sets obtained with analytical and simulation methods using the FlexSim software.

“…This, however, forces continuous exploration of new possibilities of forecasting of the impact of this type of noise on the environment. The assessment of acoustic effects and noise is already a well-researched topic in the road vehicles application [1,42]. In the aviation, both in the civil and the military ones the noise is the constantly researched problem.…”
