Strutt is Arup's Acoustic Calculation Software which was first released (internally) in early 2007. It is designed to help acoustic engineers to undertake acoustic calculations by using standardised equations and functions (for example, inserting fan noise levels, transmission losses of elements, logarithmic addition and barrier loss calculations).
Specifically, it is a Microsoft Excel Add-In that provides access via the Strutt menu to a whole host of standard acoustic calculation elements. So Strutt runs under Excel allowing you to use all the power and familiarity of Excel to do your calculations.
It will help you do acoustics calculations faster, and more accurately. It does this by helping you to input standard input data (eg. fan noise levels, sound levels, transmission losses), applying standard acoustic equations (eg. Logarithmic addition, Barrier loss, reverberant noise levels), and calculating outcomes (eg A-weighting, NR ratings).
During the last 8 years Strutt has been subject to the daily rigours of use by our engineers throughout the world - and constantly updated and improved into the robust and comprehensive software that you see today.
Strutt has been developed by acoustic engineers at Arup and was first released externally in 2015.
Strutt is named after John William Strutt OM, PRS, who was the 3rd Baron Rayleigh, and commony known as Lord Rayleigh. Rayleigh was an english physicist who is the 'father' of modern acoustics practice who published his seminal textbook The Theory of Sound in 1894, and won the Nobel Prize for Physics in 1904.
In addition, Struts (with only 1 't') are also 'structural elements used to strengthen a framework' which references not only the calculation paradigm adopted when using Strutt, but also the Structural Engineering heritage of Arup.
