- Design and validation of Acoustics performance as part of New product and technology programs. - Turbine level machinery noise target setting and cascading - Defining acoustic part specification and testing standards. - Field and Lab testing - Designing passive dampers to mitigate structure borne noise issues and sound absorption materials to mitigate air borne noise issues. - Noise risk assessment - R&D of advanced Tool suite - Experimental Modal analysis - Operational Modal analysis

- Objective and subjective validation of Prototypes against set Noise and Vibration targets for New Motorcycle and scooter models. - Objective and subjective benchmarking of competitor products. - Setting up Quality metrics for acoustics and vibration performances and monitoring those metrics during Mass production. - Root cause study for customer complaints and developing countermeasures proposals for Engine noise, Generator noise, Exhaust noise, Fuel injector noise and tactile vibrations.

- Objective validation of Prototypes against set Noise and Vibration Transfer function targets for Passenger cars in semi-anechoic chambers. - Perform contribution analysis and define sub-system transfer function targets. - Root cause study for system-level NVH exceedances using techniques such as Sound intensity mapping, transfer path analysis, Elimination trials and correlation study between dynamic and transfer function measurements. - Applying mitigation options for structure-born and airborne issues.
