This paper deals with one-phase faults on high voltage transmission lines and possible methods of utilization of the transmission capacity of the sound phases. If an AC power grid has interconnections with damaged or disconnected single phases, non-symmetrical currents arise in the system. These non-symmetrical currents must be eliminated to provide an acceptable and secure operation of the pow...

A commonly encountered argument for using sound in games is that sound increases the sense of immersion of a game. Immersion refers to an experience of being drawn into the game world, a process is centrally dependent on the players’ simultaneous removal from everyday life also called disassociation. The immersive power of sound has been linked to its capacity to disassociate: to transport the ...

The direction-dependent acoustic ltering of the external ear plays an important role in sound localization. It is believed to be essential for the detection of sound elevation, whereas sound azimuth follows from binaural diierence cues in intensity and phase. Sound elevation is believed to be coded by prominent and characteristic features in the sound power spectrum at the sensory level, like p...

A noise abnormal rotary compressor is analyzed with sound quality evaluation method. Sound power level (A), loudness, roughness and sharpness are calculated as objective evaluation parameters, and the results indicate that the abnormal compressor has a poor sound quality compared with a normal one. Acoustic array technique can identify target sound source of complicated shape accurately, and ge...
