The paper presents results of determination of sound source localization based on signals measured by first-order ambisonic microphone. The experiment consisted in recording the test signals with the 3D microphone positioned in the axis of the turntable in the anechoic chamber. The spherical coordinates of the sound intensity vector were calculated and compared to actual values resulting from t...

The aim of the presented research is to determine whether the perception of reverberation is dependent on the type of sound stimuli used. We quantified the discrimination thresholds for reverberations that are representative for large rooms such as concert halls (reverberation times around 1.8 s). For exponential decays, simulating an ideal simple room, thresholds are around 6% (Experiment 1). ...

The ability of people, and of machines, to determine the position of a sound source in a room is well studied. The related ability to determine the orientation of a directed sound source, on the other hand, is not, but the few studies there are show people to be surprisingly skilled at it. This has bearing for studies of face-toface interaction and of embodied spoken dialogue systems, as sound ...

IT fashions are IT innovations within a hyped phase. They are on the rise and claimed to be “the next big thing”. Investing in IT fashions bears potential for high returns in case the technology becomes institutionalized and first mover advantages can be realized. Contrary, it bears the risk of investing in a losing technology. By waiting for others to make the first move organizations bypass t...

This paper proposes a novel conceptual system of optical wireless power transfer (OWPT) between objects, which is different from the existing OWPT systems such that single device—an transceiver—is employed. transceiver, capable both absorbing and emitting light, fabricated metal halide perovskite known for its superior features can help significantly reduce whole size cost. The proposed contrib...

Current automobiles’ safety systems based on video cameras and movement sensors fail when objects are out of the line of sight. This paper proposes a system based on pulsed neural networks able to detect if a sound source is approaching the sensor or moving away from it. The system, based on PN models, compares the sound level difference between consecutive instants of time in order to determin...

We present a novel particle filtering algorithm for tracking a moving sound source using a microphone array. If there are N microphones in the array, we track all ( N

In this study, a contribution separation technique using only response signals were considered for an analysis of vehicle interior noise. Independent component analysis (ICA) was applied for the technique. To verify and consider the applicability of the method in contribution separation, vehicle engine, road, and wind noise sources were combined artificially to simulate vehicle interior noise a...

The subjective spatial effect of decaying noise signals with interaural time difference fluctuations was investigated. These fluctuations were created by sinusoidal interchannel time difference fluctuations between signals which were presented over loudspeakers. Both verbal and non-verbal elicitation techniques were applied to examine the subjective effect. It was found that the predominant eff...
