What is the dBmap.net Noise Mapping Tool?<\/h3>\r\n

The dBmap.net Noise Mapping Tool is for modelling external sound propagation, calculating decibel levels from sources of environmental and industrial noise and the screening effects of buildings and barriers.<\/p>

This is a web app, developed for learning about and implementing the calculations of ISO-9613 and for creating interactive models that are freely accessible.<\/p>\r\n

Please read through this guide. You can print this page<\/a> and you can access it again at any time from within the Global Settings<\/b> sidebar.<\/p>\r\n

Software that runs in the browser<\/h3>\r\n
\r\n
\r\n<\/div>\r\n
\r\n

All settings are stored in the URL. This is updated every time you make a change.<\/p>\r\n<\/div>\r\n<\/div>\r\n\"\"\r\n

Save your model by bookmarking the page or share the link. Click here for more information<\/a>\r\n<\/p>\r\n

\r\n
\r\n<\/div>\r\n
\r\n

The browser back button will \"undo\" changes.<\/p>\r\n<\/div>\r\n<\/div>\n\t\t<\/div>\n\t\t

Computer requirements<\/h3>\r\n\t\t\t\t\t

Any up-to-date web browser<\/a>. Calculation times will depend on the processing power of your device.<\/p>\r\n\t\t\t\t\t

\r\n\t\t\t\t\t\t

This tool is free to use. Some features are only available when you are logged into a user account with a valid subscription.<\/p>\r\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n

Configure your model<\/h3>\r\n
\r\n
\r\n<\/div>\r\n
\r\n

The top-right button is where you can access the Global Settings<\/b> sidebar panel. Here you will find all the options for your model including configuration settings based on the calculation parameters of ISO9613.<\/p>\r\n

In there you will also find the button to open up this guide.<\/p>\r\n<\/div>\r\n<\/div>\n\t\t<\/div>\n\t\t

Calculating levels<\/h3>\r\n
\r\n
\r\n<\/div>\r\n
\r\n

Calculations are automatically run whenever a change is made to the model. You can temporarily pause this process by clicking the top-left button.<\/p>\r\n

To stop these calculations permanently, under Global Settings<\/b> change Display<\/b> to \"Noise map off\"<\/span>.<\/p>\r\n<\/div>\r\n<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t

\r\nMulti-thread calculations\r\n<\/h4>\r\n

You can speed up calculations by enabling multi-thread calculations<\/b>. This will utilise more cores of your CPU for faster processing.<\/p>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t

Saving and sharing<\/h2>\n\t

How to save the model<\/h3>\r\n
\r\n
\r\n<\/div>\r\n
\r\n

Your model is stored in the browser location bar URL. Bookmark the web page and it will save your model exactly as it is.<\/p>\r\n<\/div>\r\n<\/div>\r\n\"\"\r\n

\r\n
\r\n<\/div>\r\n
\r\n

Remember to create a new bookmark or update the old one whenever you make any further changes.<\/p>\r\n<\/div>\r\n<\/div>\n\t\t<\/div>\n\t\t

Stored in your browser history<\/h3>\r\n\t\t\t\t\t
\r\n\t\t\t\t\t\t
<\/div>\r\n\t\t\t\t\t\t
\r\n\t\t\t\t\t\t\t

Each change you make creates a new entry in your browser history, which means you can undo your changes simply by hitting the back button or going back through the history.<\/p>\r\n\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t

\n\t\t\t
\n\t\t\t\t

Sharing the model<\/h3>\r\n

As with saving, you can share the link and other users can view your model exactly as you have set it up at that moment. Their browser may be different and may recalculate at a different speed but the results will be the same.<\/p>\r\n

The URL is too long!<\/h3>\r\n

Click the Short URL<\/b> button in Global Settings<\/b>. This will use our server database to store your configuration and automatically convert it to a short URL.<\/p>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t

\n\t\t\t
\n\t\t\t\t

Snapshots<\/h3>\r\n

Subscribers can take Snapshots<\/b>, storing the model with the date and a thumbnail. Snapshots can also be given a name.<\/p>\r\n\r\n

What about sharing to non-subscribers?<\/h3>\r\n

Users who are not logged-in or do not have a valid subscription will not be able to access the subscription-only features, however any line sources and ground heights that you have added to the model will still be included.<\/p>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t

\n\t\t\t
\n\t\t\t\t

Local Storage<\/h3>\r\n

The default method of storing your model is in the URL. If your model has too many objects for this method then you will be given a prompt to switch to Local.<\/p>\r\n

\r\n
\r\n<\/div>\r\n
\r\n

\r\nLocal Storage<\/b> uses the web browser site data (similar to the cache) and is better for handling complex modelling.<\/p>\r\n<\/div>\r\n<\/div>\r\n

Use the table below to decide which method is the correct option: <\/p>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n

Best for?<\/th>\r\nSharing simple models between devices.
\r\n<\/td>\r\n		Complex modelling, e.g. detailed topography.
\r\n<\/td>\r\n<\/tr>\r\n
Does this work with browser bookmarks (or favourites)?<\/th>\r\n\r\n\r\n<\/span>\r\nYes<\/strong>\r\n<\/td>\r\n\r\n\r\n<\/span>\r\nNo<\/strong>\r\n
\r\nSave a Local Snapshot<\/b> or backup to .dbmap file instead.\r\n<\/td>\r\n<\/tr>\r\n
Can you share the URL?<\/th>\r\n\r\n\r\n<\/span>\r\nYes<\/strong>\r\n<\/td>\r\n\r\n\r\n<\/span>\r\nNo<\/strong>\r\n
\r\nShare the backup file instead.\r\n<\/td>\r\n<\/tr>\r\n
Is the Snapshot<\/span> saved in the User Account?<\/th>\r\n\r\n\r\n<\/span>\r\nYes<\/strong>\r\n<\/td>\r\n\r\n\r\n<\/span>\r\nNo<\/strong>\r\n
\r\nLocal Snapshots<\/span> are lost when browser site data is cleared!\r\n<\/td>\r\n<\/tr>\r\n
Are offline images stored with the Snapshot<\/span>?<\/th>\r\n\r\n\r\n<\/span>\r\nNo<\/strong>\r\n
\r\nUpload the image to your User Account or reload it when prompted.\r\n<\/td>\r\n		\r\n\r\n<\/span>\r\nYes<\/strong>\r\n
\r\nThe image is also stored in the .dbmap backup file.\r\n<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t
