Abstract


This study aims to determine the sound reduction ability of South Aceh marble. The research was conducted using small acoustic box approach. The parameter measured are the sound pressure level in the box before and after sample given. Sound reduction ability was determined based on the Sound Absorption Coefficient (  and Noise Reduction Coefficient (NRC). The results showed that Sound Absorption Coefficient (  of marble samples from South Aceh are less than 0,15. Noise Reduction Coefficient (NRC) of Gunung Kerambil and Alur Kering areas were 0,06, whereas, the marble sample from the Meukek area was 0,05. Consequently, marble samples from South Aceh District can be categorized as reflector material.
