BOHS webinar. Noise risk reduction has failed: it's time to change...

This BOHS organised webinar (11/03/22) brings together 3 leaders and innovators in the key noise risk reduction elements of any effective hearing conservation programme. It is only too obvious that current risk reduction programmes have failed, evidenced by the tsunami of hearing damage claims. This webinar video provides details of the 3 integrated steps that need to be taken to cut Noise Induced Hearing loss (NIHL) by 75% - 90% at little or no cost compared with current expenditure.

Time to change - NIHL risk reduction workshop

A new approach to noise risk management

We are planning a workshop based on the approaches outlined in the webinar. You can express an interest in attending or getting further information via this link.

3M engineering workshop. How to evaluate your noise control options

3M has a policy to reduce the noise exposure of employees across their sites to cut the risk of Noise-Induced Hearing Loss (NIHL) by as much as practical. Following several successful INVC noise control projects, they asked us to provide them with an occupational noise control workshop for their engineers to transfer some of the skills in-house.

The objective was to train their engineers in best practice so they could:-

  • use engineering techniques to reduce plant noise levels and hence reduce the risk to the hearing of employees
  • reduce the typical costs of noise control projects by 50% - 90% (or even self-financing) by using the best options

This video is the section of the 1-day workshop (run by our Technical Director, Peter Wilson) that covers:-

  • attitude: most engineers have a negative attitude towards noise control as the traditional approach is based on a "safety problem" mindset that results in high-cost palliatives such as acoustic enclosures that cause access and maintenance hassles. The correct approach is to view noise control as an engineering problem that can often be solved using low-cost engineering means that do not affect normal operation or productivity
  • diagnosis: illustrating the diagnostic techniques that anyone can use to evaluate the optimum noise control options. How to remove the guesswork usually associated with selecting conventional noise control measures

This video was recorded live at 3M (duration 52 minutes). Key moments at:-

02:45 diagnostic process - 05:18 cost-benefit analysis - 11:08 List noise sources - 13:01 aerodynamic noise sources - 14:06 narrowband frequency analysis - 22:10 worked examples - 36:20 tonal analysis - 43:28 diesel engine noise example - 49:01 standing waves

We provide a complete range of noise training workshops, from bespoke 1 day to full IOSH certified noise competency courses. This includes the 1-day Noise Control Master Class from which this extract was taken.

Accessing the noise control best practice database: BOHS 2020

Most organisations can reduce the risk of Noise-Induced Hearing Loss (NIHL) in many areas by 50% - 90% at very little (or no) cost (or even at a profit) by making use of the best available engineering noise control measures - e.g. cutting noise from 97dB(A) down to 94dB(A) halves the risk and PPE works better. The question is: “How do you find the optimum noise control options?”

The INVC has developed a comprehensive database of engineering noise control best practice case studies that is freely accessible from anywhere by anyone. These techniques reduce typical project costs by 50% - 90% and can even be self-financing.

Safety professionals without engineering expertise who encounter noise problems or have quotes for conventional high-cost noise control measures (enclosures etc) can search the database directly online for options.

Alternatively, they can email smartphone data (video clip and photos) acquired on site for a free cost/benefit analysis of the options based on the best of current technology.

The presentation uses multimedia case studies to illustrate how most sites can use this approach to reduce hearing damage risk dramatically at little (or no) cost. It also provides details and examples of the smartphone and other simple information required to get the most from this free noise control resource.
