Self-adhesive acoustic dampers are cost-effective

Sound Dead Steel is introducing a range of self-adhesive steel/aluminium anti-vibration acoustic dampers. They are available in 2000 x 1000mm, 2500 x 1250mm, 3000 x 1500mm sizes and cut to size.

Sound Dead Steel (SDS) is introducing a range of self-adhesive steel/aluminium anti-vibration acoustic dampers.

They are available in 2000 x 1000mm, 2500 x 1250mm, 3000 x 1500mm sizes and cut to size.

The thickness of the material can be specified from 0.5mm up to 2.0mm (there is no advantage in using more than this).

Self-adhesive acoustic dampers avoids fabrication issues; folding a laminated sound deadened sheet can result in slippage between the two layers of steel.

This is avoided by fabricating in the traditional way and bonding the SDS dampers on afterwards.

The acoustic benefits are not affected.

Self-adhesive acoustic dampers avoids welding issues; welding an acoustic laminate can be problematic, as the polymer in a laminate often isolates the two layers of steel.

The solution is to fabricate and weld in the traditional way, then apply the SDS damper on the flat areas, missing the welds and folds.

Note that SDS is currently developing a laminate that can be easily welded.

Laminates and dampers can be supplied with a high-temperature polymer or silicone powder coating, which means dampers can be fitted prior to anodising or powder coating.

SDS dampers are an effective but low-cost way to solve potentially expensive noise issues.

It is often just a simple case of applying a self-adhesive damper to the vibrating panel and observing the results.

Covering 75 per cent of the flat surface areas produces results similar to using a fully laminated sheet.

The fabrication can also be made out of a thinner gauge of steel, as the constrained layer damping principle does not rely on mass to reduce vibration.

SDS also has the additional benefit of helping to reduce metal fatigue by damping out harmful vibrations and harmonics, which makes it particularly suitable for vibratory feeders and chutes.
