Mechanical Vibrations

Vibrations are produced by natural phenomena and mechanical sources. Earthquakes, wind, waves and even thunder represent natural processes that produce a wide range of vibration effects and magnitudes. Artificial sources, including mechanical equipment and building use, are often more pervasive and sometimes disruptive to daily operations. GmE has a depth of experience with identifying vibration sources, monitoring them, and devising innovative solutions.

Our broad experience in the following areas provides our clients with a sound basis for undertaking new assignments, which are often unique.
    •   Monitoring and control of vibrations for sensitive equipment in high-technology laboratories;
    •   Control of vibrations from external transportation sources (roadway vehicles and trains);
    •   Control of structural vibrations from mechanical equipment in buildings;
    •   Assessment and control of vibrations in residential spaces.

Chillers are common sources of strong vibrations (and noise) in mechanical rooms of large buildings. Vibration control often requires specially designed isolation springs

Vibration Criteria For Sensitive Equipment
High-Technology facilities housing micro-chip and photonics research functions often have demanding requirements of vibration control technology. Steppers, probing electron microscopes and e-beam tools are a few among other equipment that require very low ambient vibration levels. In the absence of instrument specific criteria, industry accepted generic vibration criteria are used for baseline comparisons.

GmE provides expertise in the following areas:
    •   Reverberation & listening quality in large spaces;
    •   Control of noise from mechanical equipment;
    •   Silencer selection, design of floating floors;
    •   Partition selection for privacy and noise control;
    •   Design for specific NC and RC requirements;
    •   Control of vibrations related to noise reduction.

With an extensive knowledge of microclimate engineering, forensics, building vibrations, as well as environmental noise and building acoustics, GmE is uniquely suited to provide cost effective solutions on a full range of assignments. GmE uses the latest equipment and computer simulation tools to investigate and resolve difficult noise issues.
