    1. 3/18/2012 EIS Materials Workshop - Building a Semi-Anechoic Room Alan Bennetts Some thoughts on design, build and selection of materials

    2. 3/18/2012 What can reasonably achieved Ask not what I can do for acoustics but what can acoustics do for me!

    3. 3/18/2012 What is needed today ? What about tomorrow ? Can I build what I need and want with low risk of failure? Yes - however you had better be sure that you know what you want. Be careful what you wish for as for every wish there comes a curse!

    4. 3/18/2012 Target specifications Noise isolation - 10dB quieter inside than the levels that you want to measure Must conform to some, (often changing) ISO standard if the measurements are to be accepted. ISO3744 specifies the environmental criteria for sound power measurements.(in the UK most chambers will have been built to BS EN 60704-1: 1997)
