NV Dynamics was engaged by Goodrich Aerospace Services Pvt. Ltd. to install acoustic insulation solutions and to conduct noise validation measurements for their vibration shaker room facility.
The primary objective of the project was to minimize noise transmission from the shaker room to the adjacent spaces within the building and to create a comfortable acoustic environment.
To achieve this, NV Dynamics implemented a comprehensive acoustic treatment plan that included the installation of acoustic wall panels and ceiling baffles within the shaker and control rooms to reduce internal reverberation and noise buildup. Additionally, acoustically rated doors were installed at the room entrances to prevent noise leakage into nearby common areas.
Noise validation measurements were performed using a Type 1 Sound Level Meter (SLM). The SLM was calibrated with a precision acoustic calibrator prior to testing to ensure measurement accuracy. Baseline (ambient) noise levels were recorded within the shaker room and adjacent corridor while the vibration shaker was inactive. In addition to that operational noise measurements under two different shaker conditions were recorded, as specified by the client.
The results confirmed that the installed acoustic treatments—including wall panels, ceiling baffles, and acoustic-rated doors—were effective in significantly reducing internal noise levels and controlling noise transmission to adjoining spaces, achieving the desired acoustic performance outcomes.
