Automotive & Generator manufacturing industries required Engine Test chamber to perform accurate and repeatable testing of the product to study & calculate various NVH data. These test chambers are provided with controlled acoustical environment for product testing and development.
Acoustic Treatment in engine test room prevents excessive noise from inside of chamber to go side & vice-versa. For accurate designing of Engine Test Cell Acoustics modules our acousticians & engineers conduct surveys to generate various required parameter for NVH solution.
With advances in room acoustics, test equipment simulation and signal processing, it is possible to conduct noise measurements indoors with a high degree of accuracy. Vehicle Semi-Anechoic Chambers (VSACs) are typically used for the measurement of inner and outer noise & vibration of a car with 2WD or 4WD, typically during run-up and coast down and at constant speeds, including the measurement of intake and exhaust, engine compartment, steering wheel and seat rail vibrations. All VSACs supplied by Solace Acousticmeet the technical compliance of international standards including ISO 3744 and ISO 3745.
VSAC chambers may also be used for carrying out measurements of powertrain mountings (engine vibration, and vibration transfer across mounts), noise source location (acoustic intensity) and operational deflection shapes identification, structure-borne transfer path analysis from powertrain mounts and other components and measurement of engine power characteristics.
Solace Acoustichas designed and installed many VSACs in India to various specifications including some of the largest facilities ever made.
VSACs are typically designed with a 50Hz cut-off frequency using Solace Acousticstate of the art metal anechoic wedges which provide both 0.99 absorption whilst being rugged enough to stand the test of time in an industrial testing environment.
