This paper discusses issues regarding in-situ methods of obtaining sound power at a point in a heating, ventilating and air-conditioning (HVAC) duct system. Such a method is being used as part of a larger investigation on acoustical prediction methods to allow for comparison of measured data to results from attenuation predictions of individual duct elements, such as elbows or dampers. Sound pr...

The present study investigated the influence of acoustical characteristics on the implicit learning of statistical regularities (transition probabilities) in sequences of musical timbres. The sequences were constructed in such a way that the acoustical dissimilarities between timbres potentially created segmentations that either supported (S1) or contradicted (S2) the statistical regularities o...

In adults, neural networks for phonological processing distinct from those involved in acoustical processing are located in the left temporal lobe. We now report that by the age of 3 months, infants display phonological processing devices analogous to those found in adults. Within a stream of identical syllables, acoustic deviants were introduced, either crossing a phonetic boundary or remainin...

In this study, we introduced a new model of how a human understands speech in real time and performed a cognitive experiment to investigate the unit for processing and understanding speech. In the model, first humans segment the acoustical signal into some acoustical units, and then the mental lexicon is accessed and searched for the segmented units. For this segmentation, we believe that proso...

There is a general lack of publications on the acoustical and related non-acoustical properties nanofibrous media. This work attempts to contribute this gap highlight problems associated with acoustic non-acoustic characterisation these materials. The work, presumably for first time, applies Biot- Darcy-type mathematical models explain observed behaviours nanofibres. It identifies theoretical g...

In this paper, we discuss the application of speech dereverberation techniques for post-processing of recordings taken in the German parliament. Based on a novel psychoacoustically-motivated dereverberation concept, a significant improvement in terms of the perceived quality is obtained in comparison to a conventional dereverberation approach. Since time-varying changes of the acoustical enviro...

Acoustical archeology aims to study previous acoustical stages in buildings or rooms or to recover old rooms, environments or buildings that has been lost. This part of the acoustic science also tries to analyze the historic acoustic evolution of emblematic buildings of our Cultural Heritage. The main aim of this paper is to make a virtual acoustic rehabilitation of a ruined church, according t...
