1 Day Fan Noise Control Workshop - saving resources

various fans

This pragmatic online (or in-house) workshop provides the definitive guide to what constitutes “best practice” in assessing and controlling fan noise (from take-aways to steel works) and practical advice on effective measurement, analysis and the specification of noise limits. It includes:-

  • Diagnosis - SLM recording - analysis: BS4142 problems; how to assess fan noise; using free smartphone apps; fan noise analysis, from ears to PCs...
  • Fan noise control options: simple, low-cost retrofit noise control techniques for many common fan noise problems; materials; installation details; silencers; setting noise specifications; BAT / BPM. Includes the latest aerodynamic source control technology (silencing without silencers).
  • Remote control of fan noise - speeding up complaint resolution: getting fan noise control options and costs free by email; noise characteristics, smartphone recording, photos; fan noise control projects can improve system efficiency, making it profitable for the culprit...
  • Short cuts: how to minimise the time and resources spent on noise projects - typical savings of around 80%
“The best lecturer I have ever had with relevant case studies.” Jon Tofts: PPC officer Env. Agency
Please thank Peter for a great course. Been along time since I went on INVC course - but I realised during this course that a lot of what I apply in my work and the phrases and values I use go back to that training with Peter!
“Really good to actually hear sounds on a noise course - I liked the diagnostic approach; excellent style of presenting, case studies excellent - 100% excellent for presentation” - various, SEPA
"I did this course 15 years ago and have since completed the IoA noise diploma. This presentation is still the most complete refresher in acoustics I've seen. The remainder of the course is full of practicable examples of real world noise control for EHOs. Would thoroughly recommend." Patrick Chisholm, EHO, Darlington Borough Council

Location: online or it can be delivered in-house e.g. at a host local authority, inviting EHOs from across the country. This provides high-quality training at a startlingly low cost.

Course outline: 1 day workshop designed for EHOs, Environmental Agency staff and regulators involved in occupational, environmental (and planning) noise where fans are a common issue.

Learning objectives and outcomes:  provide delegates with the knowledge to analyse and assess fan noise and detailed guidance on the mitigation options, including the latest technology.

Accreditation: an INVC attendance certificate is issued
Qualification: 2 CPD Points
Relevant regulations etc: BS 4142-2014; the Control of Noise at Work Regulations 2005; planning requirements, Buy Quiet purchasing policies

Profitable noise training - in person or online

This noise training course is run online or at a host site. Once a date has been selected, EHOs from other authorities can then be invited. This dramatically reduces costs and the course is often over-subscribed. Some authorities have even made a profit or run the training twice... High-quality training at the time of your choice and at 10% of the cost.

  • Measurement parameters: what are the best measurement parameters for assessing fan noise? dB(A, (C), (lin), Leq, Lns - frequency analysis: 1/1, 1/3 octave, narrow band - setting noise specifications
  • Sound propagation: the behaviour of sound and acoustic materials - decay with distance - sound transmission in ducts - standing waves - acoustic absorbents and insulation
  • Fan sound power: use manufacturers’ sound power data to calculate noise levels - prediction of fan noise levels - typical fan signatures
  • Fan noise control: installation details - source control - damping - vibration isolation - silencers (reactive, absorptive) - simple “Blue Peter” solutions for many common problems on small fans - BAT
  • Diagnosis - Recording - Analysis: calibrated noise recording - time and frequency analysis - smartphone recording and analysis
  • Remote Control of Noise: putting together the information required for free noise control option evaluation by email

Delegates can email current or past problem case studies in advance for a free analysis and evaluation and for discussion.

Ideally to have some experience of environmental or occupation noise issues that involve fans. Other than that, none...
