The traceability of acoustics measurement in Indonesia nowadays

Abstract

Abstract Acoustics or sound measurement has an important role in industrial and environmental noise control, hearing health checks, and building acoustics. Therefore to ensure the acoustics measurement results, the acoustics instruments used in the measurement should be calibrated and traceable to a reference standard. Acoustics measurement traceability has been established in Indonesia, however, in the year 2019 coupler method for SLM calibration and audiometer calibration have been added to comply with the acoustic traceability needs. This paper gives a brief description of acoustics measurement traceability that is applied by the National Measurement Standard (SNSU) for Acoustics and Vibration of National Standardization Agency of Indonesia (BSN) nowadays in Indonesia.
