Use

Provides:

• the room effect to enable the determination of the sound pressure level at a location within a room when subject to a sound power level
• predicted reverberation time within a space based on sabine calculation

This element allows the user to input a known RT and volume to characterise the space.

As per the Room element; however, enables the inputs of reverberation time in lieu of selection of a range of different room and space types.  Subsequently provides the room effect to enable the determination of the sound pressure level at a location within a room when subject to a sound power level.

User Inputs

1. Length (m): Room length
2. Width (m): Room width
3. Height (m): Room height
4. Distance (m):The distance from the source to the location in the room to enable the calculation of the direct component of noise in the room
5. Materials: Input floor, ceiling, walls area & absorption data
6. Source Directivity: The directivity of the source with respect to the direct component (free space, hemispherical, etc;)
7. Noise Criterion: Can select NC curve if desired.

SoundSurfer Input

Sound Power Level (red node) entering the room or in the space.
