We are developing a system to acquire 3D sound-space information that can transmit accurate sound-space information to a distant place using a microphone array on a human-head-sized solid sphere with numerous microphones on its surface. The system comprises an object with numerous microphones called Symmetrical object with ENchased ZIllion microphones (SENZI). Each recorded signal from spatiall...

There is a growing interest to introduce auditory interface into home appliances to improve their usability. However two issues hinder the penetration of utilizing sound for home appliances. (1) High design cost Information sound design requires both significant expertise and long development time. Information sounds are usually designed by a cut-and-try approach, because no systematic methods ...

This paper proposes a spiking neural network (SNN) of the mammalian subcortical auditory pathway to achieve binaural sound source localisation. The network is inspired by neurophysiological studies on the organisation of binaural processing in the medial superior olive (MSO), lateral superior olive (LSO) and the inferior colliculus (IC) to achieve a sharp azimuthal localisation of a sound sourc...

background : cement industry has many process units. basically all of these units can be considered as a source of noise. since noise pollution is defined based on its offensive hearing effects, the importance of the noise sources depends directly on the number of workers in the unit.   materials and methods : an experimental study has been done at tehran cement factory to recognize and analyze...

The appropriate use of nonspeech sounds has the potential to add a great deal to the functionality of computer interfaces. Sound is a largely unexploited medium of output, even though it plays an integral role in our everyday encounters with the world, a role that is complementary to vision. Sound should be used in computers as it is in the world, where it conveys information about the nature o...

This paper was initially presented at the CEDA Dredging Days in November 2015 and was included in the conference proceedings. It is reprinted here in an adapted version with permission. Underwater sound from anthropogenic sources and its potential adverse effects on the marine environment is a topic of much global interest. In recent years, there is recognition that sound from some shipping and...

background: the basic requirements for monitoring anesthetized patients during surgery are assessing cardiac and respiratory function. esophageal stethoscopes have been developed for this purpose, but these devices may not provide clear heart and lung sound due to existence of various noises in operating rooms. in addition, the stethoscope is not applicable for continues monitoring, and it is u...

The present in used distance education system is based on audiovisual communications. So when a teacher gives lessons to many students who are dispersed in distant places, the teacher obtains input from students through image and sound information. The students can be visually distinguished by separately displaying an active picture and a non-active background. But it is hard to distinguish the...
