NoiseMap is designed for a team-working environment, although its design will\u00a0simplify the life of the individual noise specialist too.<\/p>\n
Teams may be covering different geographical areas of a project; they may even be working from different offices.\u00a0 Some people will be creating the models, some will be analysing the results. Others will be managing progress, checking the quality and reporting to clients. These aspects are just as important as the actual calculations.<\/p>\n

The system is cleverly designed so that you can get many computers helping with the calculations, yet if one computer is slow or crashes, the other computers will continue and complete the task.\u00a0 You can even have a ‘slave’ computer that does nothing but listen to the calculation queue and we have a\u00a0special low-cost licence for these\u00a0‘calculation’ computers.<\/p>\n Because of this, even the smallest consultancy can benefit from a ‘Remote Server’ licence, if it does regular noise mapping work.<\/p>\n How do you make sure that the whole team can work as one?\u00a0<\/strong> Scenarios<\/strong> Previewer<\/strong> Quality Assurance There are many other built-in checks – such as indicators to show you traffic flows that have not been applied, or\u00a0how many tracks a train service runs along.\u00a0 There are also error-removal tools, such as receiver points that have been placed within buildings.<\/p>\n These tools have all been developed through the practical experience of our developers and our users.<\/p>\n Results Manager<\/strong> Scripting <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" NoiseMap is designed for a team-working environment, although its design will\u00a0simplify the life of the individual noise specialist too.

\nNoiseMap’s Remote Server<\/strong> system can deal with huge schemes, perhaps containing hundreds of kilometres of roads or railways, or hundreds of scenarios.\u00a0 The server may be located on a private network or on the internet. The system is specifically designed for working over the internet, where connections may sometimes be slow or unreliable.\u00a0 NoiseMap has a remote server hosted in the ‘cloud’ which can be accessed over the internet for a modest charge.\u00a0 This server is located in a UK datacentre with gigabit internet connections and world-class security measures, including backup and archiving facilities.<\/p>\n
\nThe cloud server\u00a0is useful for those who do not wish to set up their own server, or where various companies are working together on the same project. In such a case, it makes sense for all the participants to share the one database as this enables seemless collaboration.\u00a0 It avoids the complexities of different IT departments having to allow access to a server within their firewalls and allows the acoustics professionals more control over their resources.<\/p>\n
\n<\/strong>A major benefit of the Remote Server system is the ability for many computers to share in the calculation load of large projects which may require many thousands of tiles to be calculated.\u00a0 With large schemes, this can take many hours of CPU time: Distributed Computing allows other computers to share in the calculations thereby\u00a0reducing the waiting time\u00a0to a fraction of what would otherwise be required.<\/p>\n
\nA crucial aspect is Version Control<\/strong>.\u00a0 You need to be sure that everyone is working on the same version of the model and with the same calculation parameters.\u00a0 NoiseMap does this by only having one version of the model that everyone shares, but it is easy to make backups (both automatically and manually) just in case someone makes a mistake that needs to be reversed.\u00a0 Every change is logged within the database, so that if you discover a blunder made some time earlier, you know exactly when it occurred and what might have been affected.<\/p>\n
\nWhat if you want to make a change, but leave the original version of the model unaffected?\u00a0 NoiseMap has thought of that too.\u00a0 You simply save the changed version of the model as a new scenario<\/strong>.\u00a0 You then have the original and new scenarios within the database and you can quickly switch back and forth between them.\u00a0 The scenario tool is extremely powerful and can be used for things like\u00a0differences between day and night conditions as well as different designs for the scheme itself.\u00a0\u00a0 You can have any number of scenarios in the database.<\/p>\n
\nThe previewer system lets you see\u00a0the differences\u00a0between the scenarios.\u00a0 Also, you need to be able to divide large schemes into manageable areas.\u00a0 There are many ways of doing this, but a convenient way is to divide the scheme up into ‘Named Areas’, which allows you to quickly select a particular area of the model.<\/p>\n
\n<\/strong>There are so many elements to a noise model that it is not always easy to know where to start when doing your quality assurance checks.\u00a0 The ‘View-As-Colour’<\/strong> tool is specially designed to help you with this.\u00a0\u00a0You can select almost any property of\u00a0the objects in the model and display it\u00a0in colour, as in a ‘thermometer’ chart.\u00a0 This can quickly show missing parameters and\u00a0incorrect values, allowing you to identify and fix errors quickly.<\/p>\n
\nA large scheme will produce thousands or millions of results and it is essential to be able to manage these.\u00a0 NoiseMap stores all of its results in the database, along with all the essential details of the calculations. This enables you to see what has been done, and what has not been done.\u00a0 It also lets you check which ones need to be re-done because of changes to the model. But you may need to process the calculations in some way – for example to get the change of noise level between scenarios; to add two noise sources together; to add a background level; to put in a noise floor.\u00a0 NoiseMap’s Results processor lets you do this easily.\u00a0 You can even put in a measured noise level as a background.<\/p>\n
\n<\/strong>For efficiency with a large team or project, you need to automate repretitive processes.\u00a0 This is where scripting comes into its own: you can develop a ‘script’ i.e. a procedure or set of instructions for NoiseMap,\u00a0that users can run to undertake a pre-defined process.\u00a0 Some very advanced users have even produced systems that automatically create scripts.\u00a0 These can help to ensure that repetitive work is done to a consistent procedure.<\/p>\n
