Examples of Self-Financing Noise Control projects across a wide range of plant categories and industries that illustrate the cost savings inherent in engineering noise control measures at source compared with conventional palliatives such as acoustic enclosures, silencers, lagging etc. In many cases, noise control modifications are installed as an extension to maintenance and can be justified simply on the grounds of increased performance, efficiency and productivity, with the noise reduction as an additional benefit. Typical noise control savings of 50-80% with no maintenance or access issues, no hygiene implications, the potential to eliminate PPE / audiometry and to remove remove existing acoustic enclosures and to improve productivity
HAV Risk Management Best Practice - Myths and RealityPeter Wilson
This presentation is a pragmatic guide to current best practice in hand arm Vibration (HAV) risk management. It includes the myths surrounding vibration risk assessment, PPE (simple, there is none...) and other red herrings that can waste resources that would be better spent on risk reduction.
Environmental "noise industry" is not fit for purpose...Peter Wilson
The "noise industry" is generally woefully ignorant of diagnostic techniques and modern noise control methods. Consequently, thousands of people are needlessly exposed to stressful noise over prolonged periods, resulting in unnecessary deaths from stress (BMJ/WHO reports). Very large sums of money are also wasted on inappropriate mitigation - there is a diagnostic process that must be followed to evaluate any noise nuisance problem. The presentation includes case studies illustrating how so much money has been wasted on poor diagnoses and inappropriate noise control measures - plus examples of how it should be done using best practice...
The need to protect workers from diesel particulate matter (DPM) has led the underground coal mining industry to install disposable filter systems on their vehicles. While the disposable filters are efficient at removing significant DPM some major issues have arisen. ACARP, the Australian Coal Association Research Program funded two projects to research and develop solutions to these issues. This presentation provides the key findings from ACARP project C26070.

Noise Control Stratagies in Reinforced Concrete BuildingsIJRES Journal
This study is aimed at bringing out the salient aspects of building noise control. An analysis has been carried out with respect to the noise transmission as well as the characteristics of noise inside buildings. The key issues on building noise control have been included and discussed. A comprehensive study on building noise and on acoustically divisible spaces has been made. It has been observed that a sound insulation of the order of 30 to 35 dB is possible in a given building. Further, the noise propagation parameters in an exhibition hall have been theoretically estimated. The data so obtained has been compared with actual SPL measurements and recorded. Variations in noise levels observed have been explained. Before the partition is made, the SPL drop is faster inside the building but after the partition the drop falls at the rate of 3dB for doubling the distance. The cost of the acoustically divisible partition wall is found to be very high, but the advantage of this partition seems to be creating acoustically divisible spaces where in one can conduct two programs simultaneously, without any disturbance to each other. Prior to the selection and design of control measures, noise sources must be identified and the noise produced must be carefully evaluated.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Noise Control Best Practice Elements
• Attitude
• Noise Control Audit
based on detailed diagnosis and costing of the options and benefits
using the best of current technology
• Implement Noise Control Programme
based on the results of the audit
• Update Noise Assessment
de-regulate areas; reduced PPE costs ...
• Buy Quiet purchasing policy
This approach can produce noise control measures that actually improve
productivity and reduce costs - in contrast to reliance on conventional
enclosures and acoustic guarding.

Noise Control is ....
Noise control is not a safety issue
• Noise control is an engineering problem that should be solved by
engineering means, in particular through noise control at source.
• Effective noise control must be based on an accurate diagnosis and
not on assumptions
• All the options must be considered, not just the conventional high
cost palliatives of enclosures and silencers. These techniques should
only be used where it can be proved that there is no engineering
alternative.

The Noise Control Audit
Objectives
• generate cost v noise reduction trade-offs for each item of noisy plant
• assess the noise control options across the company using the best
of current technology
• plan the most practical and cost effective noise control programme
possible across the company
The results of the Audit also take into account factors such as:-
• hygiene: access / maintenance
• productivity
Where the audit proves that control is impractical, it also provides
certification so that PPE can be used for long term risk control.
12. www.invc.co.uk
BPM Noise Control Audit Steps
• List all the potential noise sources on each piece of noisy plant
• Rank the sources
• Assess all the noise control options for the dominant source
potential reduction in noise from this source
operational, productivity, hygiene constraints
operator acceptance
cost
• If engineering control is not practical for the dominant source, then
you have proved that screening / enclosure etc are the only options
The results are used to generate cost v noise reduction trade-offs for
each item of noisy plant and to plan the most practical and cost effective
noise control programme possible across the company.

Innovative Noise Control Materials
We are at the forefront in developing applications for new and innovative
hygienic noise control materials. The two materials that have had most
impact on our work are:-
• High hygiene acoustic absorbent
existing guarding and enclosures
room acoustics (walls and ceilings)
• Laminated steel – sound deadened steel sheet
looks like stainless steel, sounds like rubber…
These materials have provided us with two additions to our armoury in
developing the next generation of hygienic noise control techniques.

customers to reduce noise levels. For many
applications, access and hygiene are very
important.
Conventional Approach
Covers and enclosures: high cost (up to several
£000s) plus access and hygiene problems.
BPM Solution
Engineering modifications – minor design
changes plus high efficiency damping of critical
components - reduced noise at source by 5dB(A).
Licensed to implement the technology either
during build or as a retro-fit kit. No access,
maintenance or hygiene implications
Cost £200 / unit.

Noise Control Programme Best Practice
• Noise Control Audit
engineering evaluation of the noise control options (costs / benefits) –
both occupational and environmental
• Develop detailed noise control recommendations for each category of
occupational plant
implement as retro-fit on the first of each type of machine / plant
• Develop noise management programme – as required – for
environmental noise
• Buy Quiet – Occupational and Environmental Policies
• Training
