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...

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
15 صفحه اولEvaluating Coordinate Measuring Machine Software Geometry Uncertainties Using National and International Standards
In coordinate metrology, evaluating task specific measurement uncertainty can be difficult, a problem which prompted the current development of several related standards at the national and international levels. Software that processes coordinate data can be an important, but often overlooked, component of measurement uncertainty. This paper describes the historically significant role software ...
متن کاملSound insulation issues
This paper gives an overview of three topics related to sound insulation in buildings. The first project included laboratory and field measurements of sound insulation against aircraft noise. As well as various technical papers, the project produced software to help in the design of adequate sound insulation. In a second project, re-analysis of survey results allowed the development of a ration...
متن کاملHow much protection do the sound insulation standards give and is this enough?
Social surveys in several European countries have shown that inhabitants of multifamily dwellings are considerably annoyed by noise from their neighbour's activities. This is also in countries where sound insulation minimum requirements exist and have been enforced for many years. It is therefore necessary to establish data on the sound levels of activities in residential buildings and undertak...
