Case Studies

An elegant engineering solution to your noise or vibration problem may already be available. Search below the largest database of source control case studies in the world for alternatives to conventional, high-cost palliatives such as acoustic enclosures, silencers, barriers etc.

Mill Bearing Failures

Bearing failures on a food processing mill continually recurred despite careful overhauls. Vibration signature comparisons with a second mill indicated a loose rear bearing. This diagnosis was confirmed in strip-down – the rear bearing was found to be turning in its housing.

Gearbox Faults

The motor/gearbox on a large fermentation vessel suffered varying motor current and intermittent noise. Downtime would be costly due to the production schedule. Single point vibration analysis indicated excessive input shaft float – very unlikely (due to the construction) but confirmed later on partial strip-down (25 thou v 6 thou specification). Pinpoint accuracy.

Impact Noise Control – chutes, bins, conveyors, hoppers…

We have developed a suite of innovative and elegant engineering impact noise control techniques that typically provide 10-20dB reductions. These are both much more effective than conventional technology and very much lower cost and rugged. We custom design the modifications either for new designs or for retro-fit to existing installations. We also have high hygiene versions for the food and pharmaceutical industries.

  • Applications: chutes, hoppers, conveyors, bins, recycling plant, scrap yards, train/truck loading/unloading, quarries …
  • Benefits: large attenuations, rugged (often harder wearing than the untreated surface); very low cost; hygienic

Additional Noise Control Examples

We have a host of other engineering noise control applications across a wide range of industries – contact us to discuss particular plant or machinery in detail.
