Industrial Vibration & Noise
Scope of Work
MD Acoustics was engaged to investigate a persistent low-frequency noise condition affecting an occupied control room located adjacent to industrial processing equipment. Personnel reported a continuous rumbling sound and vibrational sensation that interfered with communication and created an uncomfortable working environment. The effort focused on identifying dominant noise sources and understanding how mechanical energy from nearby equipment was transmitting into the occupied space.
MD Acoustics conducted on-site acoustic and vibration measurements to characterize the operating conditions of the industrial sifters and evaluate the resulting sound and structural responses within the facility. The collected data was analyzed to identify dominant frequency components and potential resonance conditions influencing the perceived noise. Findings from the field investigation were used to guide the development of targeted mitigation strategies aimed at reducing the transmission of low-frequency energy into the control room.
Outcome
The measurement program identified a dominant low-frequency resonance associated with the operation of the industrial sifting equipment. Analysis indicated that structural elements within the building envelope were being excited by this energy and acting as secondary radiators, allowing the low-frequency noise to propagate into the nearby control room environment.
Based on these findings, MD Acoustics developed practical mitigation recommendations focused on interrupting the transmission pathways and reducing the structural excitation responsible for the disturbance. The resulting strategies provided the facility with implementable options for improving acoustic conditions within the control room while maintaining normal equipment operation and production activities.
