Low Cost Fan Noise Attenuation in the Power Industry

Schiller biofuel power station fan noise attenuation.jpg
Posted on: June 24, 2013

An article about the application of our Quiet Fan technology (QFt) to reduce the noise from large fans feeding stacks in the power industry has been published in Power Engineering International. The journalist suggests that the widespread adoption of the technology in this industry could reduce both capital and running costs very substantially compared with conventional fan silencing techniques – i.e. traditional attenuators, acoustic lagging and enclosures.

He uses the example of the 50MW Schiller biomass power station in the USA (the largest station of its kind) where the massive 2 storey ID fan feeding the stack (shown below) was modified in only 12 hours (that’s not a misprint – just 12 hours from noisy to quiet) to reduce the fan noise by 10dB at fraction of the cost and with a much lower power consumption compared with the conventional fan noise attenuator previously fitted.

Acoustic Shock – Shock!!

Posted on: June 18, 2013

Doesn’t the term “Acoustic Shock” sound nasty? If you renamed it “unexpected somewhat louder headset noise than usual that is still at only a tiny fraction of the noise level that is deemed to cause hearing damage in industry”, it wouldn’t sound so bad.

Satisfying Super-Sensitive Complainants with Psychological Silencing

Posted on: July 10, 2012

If you play white noise to a group of people and tell them that the song “White Christmas” is hidden in the sound, about 30% of them will be convinced that they can hear it. The human mind is always looking for patterns – even when they aren’t there.

Noise Kills – New WHO Data Quantifies the Risks

Posted on: July 10, 2012

Noise is stressful and can damage your health – particularly if you show up at 3am to an all-night party asking them to turn the noise down… New evidence collected by the World Health Organisation indicates that c 3% of deaths from heart disease is attributable to long term exposure to environmental noise – mainly nighttime noise exposure, with 2% of the population suffering from severe sleep disturbance, 15% from serious annoyance and with additional significant effects on the learning abilities of children. As noise complaints in the UK have increased by a factor of 5 over 20 years, this indicates that the problem of LOUD NOISE is rapidly getting worse.

Apparently, high levels of noise do not damage your hearing…

Posted on: July 2, 2012

… as long as the “noise” is music. Thus spake Richard Littlejohn of the Daily Mail earlier this year – he’s a journalist, for some value of “journalist”. “Blessed is the man who, being ignorant, abstains from giving us worthy evidence of the fact” (with apologies to George Eliot). This journalistic licence is addictive, I feel better already…

In-Ear Noise Assessment Instrumentation

Posted on: June 30, 2010

We have invested in the latest in-ear microphone technology to simplify noise assessments on personnel who wear helmets or other protective equipment that makes conventional noise assessment difficult. It can also be used to assess noise levels inside PPE to evaluate operator exposure against the Exposure Limit Value (ELV) of 87dB(A).
