Abstract In the aspect of state monitoring hydropower unit, main technical means is to collect and monitor data on site by deploying various sensors cameras in unit its affiliated units, relying computer system system. However, it difficult intuitively feel audio characteristics when running. Therefore, an equipment fault diagnosis based analysis technology proposed, which makes use analyze pro...

Introduction My previous note focused on pin 1 problems as an open door for RF into audio equipment. But RF can also enter equipment on the signal conductor(s) if the equipment fails to block it with an effective low pass filter. RF is induced on a shielded balanced pair by at least three mechanisms: • Imbalance in the magnetic coupling between the shield and the two signal conductors (Shield-c...

In order to achieve full binaural sound, audio signals must be synthesized using specialized digital filters characterized by their so-called Head-Related Impulse Responses (HRIRs). They represent the modification to sound due to the listener’s torso, shoulders, head and pinnae, or outer ears. Conventional methods of measuring individual HRIRs require the use of expensive and cumbersome equipme...

Use of mobile equipment has increased exponentially over the last decade. As use becomes more widespread so too does the demand for new functionalities. The limited memory and computational power of many mobile devices has proven to be a challenge resulting in many innovative solutions and a number of new standards. Despite this, there is often a requirement for additional enhancement to improv...

Introduction Now that large-screen HDTVs (high-definition televisions) have achieved widespread acceptance, many consumers are expanding their electronics collection to include components for a complete home theater system. Home theater in a box (HTiB), sound bars, and audio/video receivers (AVRs) enhance the user experience with superb audio while complementing the HDTV video performance. The ...

The centre of computer graphics and audio-visual services in the University of Tartu was founded in 1995. Classical "teaching aid" service for faculty members of the university used to (1) design and print either single or multiple copies of overhead transparencies, slides, photos course materials, handouts, etc; and (2) design illustrations for textbooks and articles. The audio-visual service ...

It has been shown that a primary cause of VHF and UHF interference to professional condenser microphones is inadequate termination within the microphone of the shield of the microphone's output wiring, a fault commonly known as the pin 1 problem. Tests using only audio frequency test signals generally fail to expose susceptibility to radio frequency (RF) interference. Simple RF tests for pin 1 ...

This document briefly describes the application of QSound® 3D audio processing in Dolby, DTS, MPEG and other surround playback systems. The unique combination of multi-channel source formats and QSound virtual acoustic imaging provides new possibilities in affordable and upgradeable sound solutions for PC multi-media, portable and home theater systems. Also discussed is a unique surround synthe...

conclusions this study showed that audio-visual training can have a significant effect on the self-efficacy of people with type 1 diabetes. providing audio-visual equipment to referral centers of type 1 diabetics, such as hospitals, health centers, and clinics, as well as informing related officials, can be of benefit to managers. results the mean of the self-efficacy score improved significant...
