Industrial Noise and Vibration

Our experience in industrial noise and vibration covers the broad categories of engineering noise control, industrial noise exposure monitoring, structural vibrations, mechanical vibrations, and product development & acoustics rating.

Engineering Noise Control

• Abatement and Noise reduction measures. Isolation, Insulation and Absorption for airborne and structure-borne transmission. Noise barrier and enclosures design. Machinery and all other noise sources.
• Prediction of new and existing plant noise levels. Silencer/attenuator and noise reduction measures determined. Prediction of noise levels from equipment.

Previous projects included:

• Sepangar Bay Power Station, Kota Kinabalu
• BASF Petrochemical Plant at Kemanan
• Monier Concrete Paver Blocks Plant at Klang and Pasir Gudang
• Matsushita Compressor and Motor, Sungai Way

Industrial Noise Exposure Monitoring

• Evaluation for personal exposure noise levels, noise source, noise zoning, octave band frequency analysis, noise source characterization and considerations of possible engineering noise control.
• Assessment and evaluation of noise exposure with respect to occupational health and safety (OSHA) to ISO and  Malaysian Factories & Machinery Department Noise Exposure Regulations 1989.

Mechanical Vibration

• Condition Monitoring & Predictive Maintenance
  • Mechanical vibration measurements for machine health monitoring. Vibration severity and vibration analysis.  Faults detection and failure predictions.

• Vibration Diagnostics, Trouble-Shooting and Failure Analysis
  • Investigation and diagnostics of vibration problems in rotating and reciprocating machines, structures and other mechanically induced problems. 

• Vibration & Balancing Acceptance
  • Commissioning acceptance. Measurements and advice on vibration level and balancing acceptability (new and existing machines). 

• Rotor Bearing System Design Analysis
  • Computer-based real rotor analysis and simulation for rotor and bearings. Critical speeds, Mode shapes, Whirl orbits, Vibration response and stability determination.

Structural Vibration

Structural vibrations in buildings and other structures relate to concern of forced vibration excitation, and its isolation to the affected structure or buildings from mechanical equipment and external forces. This involves consideration of the following: 

• Building Vibration
  • Assessment of severity, causes and design of mechanical vibration systems for machines and plants in buildings.

• Engineering Structures Vibration
  • Measurement and assessment of structural vibration of bridges, jetties and other engineering structures.

• Vibration Isolation Design
  • Design of vibration isolated structures and floors. Design of vibration isolators and elastomers for all applications.

Product Development, Specifications Compliance & Rating

Noise and Vibration control design for products such that noise and vibration are minimized. Troubleshooting of problems in industrial and consumer products.  Testing and rating of equipment noise to appropriate standards. Specifications evaluation & determination. Commissioning tests.
