“…Results are analyzed through linear mixed-effects (LME) models, predicting the overall horizontal source localization as per participants’ estimations. This part of the analysis is specifically tailored to the horizontal plane, the region most frequently used in experiments testing speech-in-noise perception or related metrics such as spatial release from masking (see, e.g., Cameron & Dillon, 2011; Ozimek et al., 2013), representing one main application area of the system. Additional analyses compare reversal rates as well as angular error metrics across experimental conditions, including sound sources on the horizontal and median planes.…”

Auralization systems for auditory research should ideally be validated by perceptual experiments, as well as objective measures. This study employed perceptual tests to evaluate a recently proposed binaural real-time auralization system for hearing aid (HA) users. The dynamic localization of real sound sources was compared with that of virtualized ones, reproduced binaurally over headphones, loudspeakers with crosstalk cancellation (CTC) filters, research HAs, or combined via loudspeakers with CTC filters and research HAs under free-field conditions. System-inherent properties affecting localization cues were identified and their effects on overall horizontal localization, reversal rates, and angular error metrics were assessed. The general localization performance in combined reproduction was found to fall between what was measured for loudspeakers with CTC filters and research HAs alone. Reproduction via research HAs alone resulted in the highest reversal rates and angular errors. While combined reproduction helped decrease the reversal rates, no significant effect was observed on the angular error metrics. However, combined reproduction resulted in the same overall horizontal source localization performance as measured for real sound sources, while improving localization compared with reproduction over research HAs alone. Collectively, the results with respect to combined reproduction can be considered a performance indicator for future experiments involving HA users.

“…Weighing with the A filter has become the most commonly used frequency factor, although it is not optimal for all sound pressure levels. Studies on sound perception show that the harmonics of sound with frequencies in the range 1÷5 [kHz] are more audible than the others [16]. This is important in interpreting the occurrence of elementary and complex phenomena in low and high frequency ranges [15].…”

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.
