Strutt|Input Data|Library|Transmission Loss allows the user to input transmission loss values from either Strutt's internal database, a generic database, or the Arup Acoustics Intranet Transmission Loss Database into the active row of the worksheet.
The user may view all transmission loss data or may restrict the search to a specific category using the drop-down menu. Option buttons are used to switch between the databases. The intranet database is accessed through Arup Acoustics London network, and so in other locations there may be a brief delay while data is retrieved. When switching from one data category to another, the categories in the drop down menu are automatically updated to display the available categories in each database.
