A room may be used for a wide variety of performances and presentations. Each use places different acoustical requirements on the room. We desire a method of electronically controlling the acoustical properties of a room so that one physical space can accommodate various uses. A virtual acoustic room is a room equipped with speakers, microphones and signal processors that functions as an intera...

This paper describes a system for Chinese pronunciation and listening training on the Internet. The target Chinese stop consonants /b/, /p/, /d/, /t/ were chosen for this experiment. In the pronunciation component, a dynamic low-pass ltered power(DLP) was used as an acoustic feature to discriminate between aspirated sounds and unaspirated sounds. With the sounds uttered by Chinese native speake...

Acoustic information contributes to the timing of human movements as sound conveys time-critical structures subliminally. That is of crucial importance for the technique training in high performance sports, where a successful movement execution depends on the precision of modifying the movement. Particularly adaptive athletes with visual impairments or blindness have a special sensitivity to ac...

Blade vortex interaction (BVI) noise has been recognized as the primary determinant of the helicopter’s far field acoustic signature. Given the limitations of design in eliminating this dynamic phenomenon, there exists a need for control. We believe that this paper is the first model-based effort to attempt the same. We present herein the application, first of feedback control strategies, and t...

Coordination of different motor systems for sound production involves the use of feedback mechanisms. Song production in oscines is a well-established animal model for studying learned vocal behavior. Whereas the online use of auditory feedback has been studied in the songbird model, very little is known about the role of other feedback mechanisms. Auditory feedback is required for the maintena...

This systematic review synthesized and analyzed clinical findings related to the effectiveness of innovative technological feedback for tackling functional gait recovery. An electronic search of PUBMED, PEDro, WOS, CINAHL, and DIALNET was conducted from January 2011 to December 2016. The main inclusion criteria were: patients with modified or abnormal gait; application of technology-based feedb...
