Acoustic Properties of Glass The sound attenuation of any material depends on its mass, stiffness and damping characteristics. With a single glass pane the only effective way to increase its performance is to increase the thickness, because stiffness and damping cannot be changed. The sound transmission loss for a single glass pane, measured over a […]
Frequency of Sound Sound is the quickly varying pressure wave travelling through a medium. When sound travels through air, the atmospheric pressure varies periodically (it kind of vibrates). The number of pressure variations per second is called the frequency of sound, and it is measured in Hertz (Hz) which is defined as the number of
Sound and Noise Sound intensity, Sound pressure and Sound pressure level .. Loudness is an intuitive concept, a loud noise usually has a larger pressure variation and a weak one has a smaller pressure variation. Depending on what we are looking for – the cause, the effect or the perception of noise – we use different
Multi Purpose Halls in History Along the history, specific building designs have been developed for some specific functions. Musical events were carried out in the prom halls and with the rising attention on music special building types were started to be designed for musical functions. Foundation of the new designs obviously based on the prom
Noise Measurement Procedure The BS 4142:2014+A1:2019 Technical Note was published by the Association of Noise Consultants (ANC) Good Practice Working Group. BS 4142:2014+A1:2019 is the latest iteration of a standard which was first published in 1967, designed to consider the effects of industrial sound with appropriate consideration to the character of that sound as well
