Why are acoustic wall products needed in modern buildings?
They reduce sound and vibration transmission between adjoining spaces, improving privacy and comfort.
Why do fans and air handling units require vibration isolation?
Fans and AHUs generate vibration from rotating components and airflow forces, which may be transmitted into structures without effective isolation. Proper isolation helps limit vibration transfer and protects connected steelwork and ducting
Why is low-frequency vibration difficult to control in generators?
Low-frequency vibration carries higher energy and can propagate over longer distances through building structures and services. Effective control depends on selecting isolation systems compatible with operating speed, load, and installation conditions.
Why is vibration isolation critical for marine propulsion systems?
Marine propulsion systems operate under continuous dynamic loading caused by engine operation, vessel motion, and sea conditions. Effective vibration isolation reduces vibration transmission, protecting equipment and structural integrity.
Why is vibration isolation important for engines in mobile and industrial equipment?
Engines generate persistent vibration that can transfer into frames, chassis structures, and operator areas. Isolation reduces mechanical stress, noise propagation, and component wear.
Why is vibration isolation important in industrial facilities?
It limits vibration transmission into surrounding structures, helps reduce noise, minimises wear, and lowers the risk of unplanned downtime over time.
Why is vibration isolation important in marine and offshore environments?
Effective isolation helps protect structural integrity, reduce noise and fatigue, and extend the service life of onboard machinery operating under constant motion and dynamic loading.
