Infrasound and Low Frequency Vibration Isolation
topic
Low-frequency vibration isolation testing measures transmissibility of textile-based anti-vibration mounts and resilient floor underlays across the 1 to 200 hertz frequency range using electrodynamic shakers and tri-axial accelerometers, calculating insertion loss and dynamic stiffness as functions of frequency and applied static preload.
Role
Characterises the vibration isolation performance of felt, rubber-textile composite, and viscoelastic nonwoven mounts used under heavy machinery, floating floor systems, and sensitive laboratory equipment where low-frequency structural vibration transmission causes equipment malfunction or occupant discomfort.
