Use

Convert the sound pressure level over an area into a sound power level.

The element can account for the transmission loss of the infill material (panel) which forms the “area”.

User Inputs

1. Panel Width (m)
2. Panel Length (m)
3. Pressure Directivity:
   1. 0 for fully direct source
   2. -1 for mostly direct source
   3. -2 for equal direct and reverberant source
   4. -4 for mostly reverberant source
   5. -6 for full reverberant source

Quick input:

1. Transmission Loss: Octave band data

From Database:

1. Go to the Project Database Editor Database
   1. Click Show Global Database rows and add relevant data from Global Database, OR
   2. Add New data into the Project Database Editor and input the Transmission Loss (input all fields including Database Origin and Source Citation so that the data can be referenced for future projects).
2. Return to main screen and select Show Search in Sound Pressure over Area element Property Inspector to select the relevant data.
3. Insertion Loss of the element (can be sourced from manufacturer’s data for a given attenuator or from the database if available).

SoundSurfer Input

Sound Pressure Level (blue node) in the room or space with the panel.
