Normal incidence sound absorption measurement of circular perforated panels using sound intensity technique
It was ascenained that, sound intensity measurement based on fixed point scanning technique could be used to measure the normal incidence sound absorption (aN) of perforated panels accurately and reliably in this paper, the importance of sound field quality indicator (F1+ F2+ F3+ F4) and sound inten...

| description | It was ascenained that, sound intensity measurement based on fixed point scanning technique could be used to measure the normal incidence sound absorption (aN) of perforated panels accurately and reliably in this paper, the importance of sound field quality indicator (F1+ F2+ F3+ F4) and sound intensity probe measurements distance toward measured aN reliability will be discussed. Individual statistical regression models that suit the measured aN for 20% and 30% perforation ratio were obtained. in addition, overall model for 20% and 30% perforation ratio were also obtained and can served as a basis for aN prediction of perforated panels with the same perforation ratio. The findings suggest, circular perforated panels. which are the simplest form of direct piercing carved wood panels ( DPCWP ) are able to act as sound absorber. |
