Don’t let your suppliers waste your money on noise control that is not best practice…Implementing and policing a noise buying policy for new plant can be either the single most cost effective – or one of the most expensive – long term noise reduction measures that a company can take.

The difference lies in the way that the noise buying policy is implemented. As most suppliers have little or no noise control expertise, they often purchase off-the-shelf acoustic enclosures, silencers and materials which they then mark-up and sell-on instead of using best practice. Suppliers have been known to continue selling noise enclosures when they know there are cheaper and more effective engineering alternatives simply because they are more profitable…
Effective and properly policed purchasing standards can save enormous sums of money by ensuring that suppliers use the best of current noise control technology to meet noise specifications rather than wasting your money on high cost conventional measures.
Buy Quiet Occupational
Once you have installed new plant that generates high noise levels, it becomes your responsibility to reduce noise levels as far as reasonably practicable. This can be a high cost process as each company independently re-invents the “noise control wheel”. Moreover, the decision to purchase may have been based on competitive prices that did not include allowances for noise control. The best way to minimise the full costs of purchasing new plant and complying with the regulations is to implement a BUY QUIET policy and order to a Noise Buying Procedure. Not only does this reduce the chance of importing fresh noise problems, but it also puts pressure on suppliers to reduce noise at source and to meet their duties under the legislation.
The fact that this vibratory grader generated 99dB(A) was picked-up prior to delivery by a company using our noise buying policy. The supplier suggested additional screens and guards at high cost and with no guarantee as to the final noise level. Our diagnostic tests during proving trials at the supplier led to the company purchasing the line subject to implementation of our recommended engineering noise control measures. These not only reduced the noise to 85dB(A) at a cost of a few £00′s (as against the several £000′s plus access and hygiene issues) previously considered, but they could also have dispensed with the existing enclosure – saving yet more money.
Noise control measures must be justified by evidence based on source diagnosis and ranking. If this information is not available, then the noise reduction techniques are based on guesswork and are highly unlikely to constitute best practice with implications re cost and productivity. If the supplier does not have the necessary expertise, then an expert engineering evaluation of the options must be made (a regular for us) and the plant purchased subject to implementing agreed best practice noise control measures.
Buy Quiet Environmental – IPPC Management
The Buy Quiet template specifications and procedures ensure you meet your IPPC Licence and ISO14001 noise specifications and requirements for the future as cost effectively as possible. The procedure includes template documentation (in digital form – with sound samples) and procedures for inclusion in company policy covering new plant and site changes. It can also be extended to include a detailed environmental noise control and management programme to minimise future costs.
Past experience with the effectiveness and cost savings realised by our noise control recommendations led CMB, for example, to include a recommendation that engineers get our evaluation of the options in all projects where environmental noise is an issue.
