Development and Validation of Sound Transmission Loss Measurement System for Measuring Muffler Performance

Muffler is a part of the vehicle exhaust system that absorb or reflect sound waves to reduce exhaust noise. One of the most important determinants of a muffler performance is the amount of attenuation that has on its input wave; this parameter is known as sound transmission loss. Four - mic standard test is one way to determine this parameter which is used in this paper. In this study, a test d...

Core Attributes of Stewardship; Foundation of Sound Health System

Although it is being practiced in most successful models of health system, but the onus to this function is still due till date. Lately, few experts in World Health Organization (WHO) have realized its importance and have been raising the issue at different platforms to pursue t...

An Intuitive Sound Editing Environment

This article presents ISEE, an intuitive sound editing environment, as a general sound synthesis model based on expert auditory perception and cognition of musical instruments. It discusses the backgrounds of current synthesizer user interface design and related timbre space research. Of the three principal parameters of sound—pitch, loudness and timbre—ISEE focuses on control of timbre, and af...

Medusa - A Distributed Sound Environment

This paper introduces Medusa, a distributed sound environment that allows several machines connected in a local area network to share multiple streams of audio and MIDI, and to replace hardware mixers and also specialized multi-channel audio cables by network communication. Medusa has no centralized servers: any computer in the local environment may act as a server of audio/MIDI streams, and as...
