About Room & Free-Field Acoustics Measurement
Room acoustics measurements characterise the acoustic behaviour of enclosed spaces — concert halls, classrooms, offices, studios — using parameters defined in ISO 3382: reverberation time (T20, T30, EDT), clarity (C80, C50), definition (D50), and strength (G). Free-field and semi-anechoic measurements require precision measurement microphones (IEC 61094-4 WS2F, WS1F), low-noise preamplifiers, and multi-channel analyzers. Placid Asia supplies Norsonic measurement microphones, preamplifiers (Nor1209, Nor1210), and conditioner systems for both laboratory and on-site acoustic characterisation.
