SILENCING – Refers to the suppression f noise generated by the flow of air, gas or steam in dusts and pipes and can be achieved by the inclusion of either absorbing material or baffles. Example – Silencer fitted on to vehicle emission.
ABSORPTION – Reduces the amount of reflected noise by using materials such as foam or mineral wool. Example – Mineral fibre marine boards (lagging) fitted on to metallic structural members of acoustic enclosures in offshore vessels.
DAMPING – Used primarily to reduce the amount of noise radiating / reverberating from large panels and is achieved by increasing the stiffness of the panel. Example – embossing onto the panel sheets, rubber-lining the panel doors etc.
ISOLATION – refers to physical separation of people from the noise source. Example – acoustic booths or havens, fitting flexible bellows in pipes etc.
