Analysis of sound pressure level (SPL) effects on various room modes in UiTMPP / Norsabrina Sihab, Rihana Yusuf and Zurita Zulkifli

The acoustic quality in certain room depends on its dimension and will response to the room modes for example the axial, tangential and oblique mode of the room. Sound of pressure level (SPL) is a parameter that can be affected by room modes and it is important to design a room or multipurpose hall....
