background: noise is one of the most important harmful agents in work environment. noise pollution in oil refinery industries is related to workers' health. this study aimed to determine the overall noise pollution of an oil refinery operation and its frequency analysis to determine the control plan for a vent noise in these industries. methods: this experimental study performed in control unit...

This article reports on the exploration of a method based on canonical correlation analysis (CCA) for the analysis of the relationship between gesture and sound in the context of music performance and listening. This method is a first step in the design of an analysis tool for gesture-sound relationships. In this exploration we used motion capture data recorded from subjects performing free han...

This study proposes an unsupervised framework for classifying heart sound data. Its goal is to cluster unknown heart sound recordings, such that each cluster contains sound recordings belonging to the same heart diseases or normal heart beat category. The proposed framework is more flexible than the conventional supervised classification of heart sounds by the case when heart sound data belong ...

The Sound Description Interchange Format (SDIF) is a recently adopted standard that can store a variety of sound representations including spectral, time domain, and higher-level models. SDIF consists of a specified data format and a set of standard sound descriptions and their official representation. SDIF is flexible in that new sound descriptions can be represented, and new kinds of data can...

All telephone systems in the world use a microphone to turn sound waves into an electrical signals and a speaker to turn electrical signals back into sound waves at the other end. But the techniques used for connecting microphones and speakers has seen considerable development over the past one and a quarter centuries. Early systems connected the microphone directly to the speaker using a coppe...

This paper addresses the role of expectation for product Sound Quality evaluation. In two different experiments it was shown that expectations (induced by priming tasks or as mood) systematically influenced how sounds are perceived. Moreover, temporary influences such as mood interacted with more stable individual differences such as noise sensitivity. These findings suggest that sound quality ...

first method, samples are collected and the concentration of DON or individual DON components are monitored over time. To measure DON flux rates using 15N tracer techniques. all of the DIN forms (N~ + , NO3 -.and NO2 -) must be removed, and the DON pool must be isolated with a high efficiency. At present. there are three basic approaches used to isolate DON-wet chemistry, ion retardation, and d...

Under a contamination of background sound noises, it seems difficult especially in a real working situation to evaluate various type statistics of only an objective sound signal fluctuation. In many cases of the noise evaluation, some signal processing method have been employed to eliminate the effect of background sound noises by first measuring emitted sound levels. In this study, a new evalu...

Digital sound rendering is the procedure for taking an analog electrical audio signal and sampling it into digital data, storing and retrieving that data, and resynthesizing a smoothed analog audio signal from the digital data. The sound rendering field has developed rapidly with the rest of the multimedia industry, benefiting from contributions worldwide. However, typical of many parts of the ...
