Spring issue of student e-zine out

The spring 2015 issue of Sound Bites, the IOA's student e-zine, is now out. As usual, it's full of a mixture of news about acoustics-related items and career advice. It's for all students with an interest in acoustics, noise and vibration and is available to any student who takes advantage of our free membership offer. Want to join?

Launch of amplitude modulation discussion

The IOA has published today a discussion document on methods for rating amplitude modulation (AM) in wind turbine noise. The document proposes a definition of AM for wind turbine noise and describes a literature review of the available methods. From this, three methods are proposed for discussion. These describe: a time-domain method; a frequency-domain method and a hybrid method. Software will be made available shortly to allow those interested to rate samples of AM using these methods. The aim of the discussion document, prepared by the Institute's AM working party, is obtain feedba

Sustainable acoustics design in practice workshop

The IOA Sustainable Task Force has been operating for over a year, and this workshop aims to be a first,
creating an exciting way to bring together at one time as many members as possible to take part in a
live linked workshop on the key areas where it has been identified that acoustics in practice can
contribute to a sustainable future. This will be about knowledge sharing around the progress made,
providing a TOOLBOX, exploring examples of action and discussing how best to take things forward.

Institute's Engineering Council licence renewed

The Institute's Engineering Council licence to offer registration at Chartered and Incorporated Engineer levels has been renewed for a further five years.

The approval follows a visit by four members of the Council’s Quality Assurance Committee to the IOA office in St Albans to review its processes with members of the Institute's Engineering Division.

IOA issues wind farm noise statement

The Institute of Acoustics has issued a statement today which explains in detail its role in respect of the assessment of wind farm noise. William Egan, Institute President, said: "In doing so, our aim is to enable members of the public to have a full understanding of our work in this field during the past few years, what we are currently engaged in doing and the area of our responsibilities.

IOA welcomes Govt wind turbine noise study

The Institute of Acoustics (IOA) welcomes the announcement that the Department of Energy and Climate Change (DECC) is to commission a study into the acoustic character of wind turbine noise known as amplitude modulation (AM) with a view to recommending how to define an appropriate threshold. The IOA had previously written to DECC informing it of the current IOA AM working group which is advancing a measurement methodology and metric to define AM, and asking DECC to commission a study to look at an appropriate threshold for AM.

Network Rail wins IOA-sponsored 'Oscar'

A mobile flash butt welder designed by Network Rail National Supply Chain (NRNSC) to minimise noise nuisance during trackside repairs has won the innovation category in the Noise Abatement Society's annual John Connell Awards.

The award was presented last night by William Egan, President of the Institute of Acoustics, which sponsored the award, to representatives of the organisation at a ceremony at the House of Commons.
