Investigation of potential numerical acoustic treatment for SMK Ayer Keroh hall

Abstract

Reverberation time is the amount takes for sound pressure level or intensity to decay to 60dB. The school hall is used as the reverberation room for testing. There are five positions to measure the reverberation time in the school hall. The equipments involved in this project are speakers, amplifier, Mini SPL microphone, Acoustilyzer and MiniLink software. The expected results from the calculation and experimental is higher than standard values. The treatment using the appropriate absorbing material is simulated.
