IOA fights to save schools' acoustic standards

The Institute of Acoustics is warning that education standards in schools could plummet if the Government drops or waters down vital design standards contained in the Building Regulations.
Trevor makes his points on behalf of the IOA regarding the importance of minimum acoustic design standards which need to be updated and strengthened (not downgraded) to account for open-plan, pupil centred learning and inclusion of vulnerable listeners in mainstream schools.

Among the areas coming under special scrutiny in a full-scale review of the regulations aimed at reducing their burden is section E4 which governs acoustic standards in schools.
The IOA fears this means that E4 is highly likely to be scrapped or be replaced by less robust rules – and it has predicted that any such changes could have “disastrous consequences” for Britain’s school pupils.
In a letter to Communities and Local Government Minister Andrew Stunell seeking an urgent meeting to discuss its concerns, IOA President Professor Trevor Cox said: “Removing E4 runs the risk of allowing school buildings to be built that are not fit for their intended purpose.
“There is a substantial body of scientific evidence that poor acoustics are linked with impaired cognitive performance in children.
“Put simply, if pupils are unable to hear what they are being taught they are less likely to be able to learn. Pupils with Special Educational Needs are especially disadvantaged. Likewise, if teachers have to regularly raise their voices to be heard due to poor acoustics, then they risk vocal damage. Only last November a teacher who damaged her voice was awarded £150,000 compensation.”
Mr Cox, Professor of Acoustic Engineering at the University of Salford, went on: “As a body we accept there is a need for updating design standards for schools to take account of the move towards open-plan teaching, pupil-centred learning and the inclusion of vulnerable listeners in mainstream schools.
“In our experience, mandatory controls are needed to maintain minimum acoustic design standards. Our members have witnessed the improvements in quality that have resulted from such controls in recent years.
“To simply remove section E4 from the Building Regulations without some other alternative statutory control risks us slipping back to the bad old days of sub-standard acoustics in schools, which is likely to have disastrous consequences for future generations of pupils.”

Master Class Room Acoustic Measurements and 3D Auralisation

On 30 March - 1 April 2011 a three day Master Class "Room Acoustic Measurements and 3D Auralisation" will take place, headed by dr. Lamberto Tronchin. At the moment there are still spots available.

Upcoming Master Class:
Building Acoustics by prof. ir. E. Gerretsen, 25 - 27 May 2011

The design of an opera house or a theatre requires a deep understanding of room acoustics. Moreover, the acoustic characteristics of the music. New insight is given by the latest techniques regarding the measurements of binaural and 3D impulse responses and 3D auralisation. The goal of this master class, headed by dr. L. Tronchin, is to evaluate the acoustic quality of an existing room starting from acoustic measurements, discuss how to design acoustic corrections and finally to simulate the new acoustics by means of 3D auralisation.

This Master Class is complemented with a workshop which includes measurements of room quality in an existing hall and the simulation and auralisation of the acoustic changes in the hall.

Traffic noise increases risk of stroke

A recently published danish study indicates that traffic noises may increase the risk of stroke, particularly for older individuals.

The study was published in the European Heart Journal, and looked at the association between road traffic noise and stroke in more than 51,000 Danish people. It was found that for every 10-decibel increase in noise level, the risk of stroke increased by 14 percent. In those over 65, the risk of stroke increased 27 percent.

Traffic noise has been linked with an increased risk of heart attacks and high blood pressure in previuos studies. However, this study is the first to examine the connection between traffic noise and stroke. The increase in risk was most significant for noises louder than 60 decibels.
