Acoustic Test Facility at FCRI FCRI has a Hemi Anechoic Chamber in accordance with ISO Standards to cater the following needs.
	Determination of sound power level of noise sources as per the standards ISO 3745 and ISO 3744. Measurement of aerodynamic noise generated by control valves as per the standard ISA 75.07/1987 Determination of noise emission values as per various International and National standards.
This acoustic environment can be used for determination of sound power levels of noise sources by precision method as per the standard ISO 3745 or by engineering method as per the Standard ISO 3744. Test objects of maximum dimension of 1 m x 1 m x 1 m can be tested inside the Hemi Anechoic Chamber by precision method.

Vibration Test Facililty The major applications of this facility are:
	Environmental testing of objects and structures Fatigue testing of specimens. Resonance searching. Study of dynamic properties of structures & structural models Calibration of accelerometers.
