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...
