-  - **3D Sound:** Add some sound to the television broadcast which grows louder as you approach the television set and softer as you move away from it.  First you need to create an instance of an **Audio3DManager** inside the **World**.  You can use the **camera** object as the reference point for calculating how far the sound is traveling and therefore how much the volume should drop.  Set the drop off factor to **10**.  Then load the sound **glenn_launch.wav** and attach it to the television screen.  Set the min distance of the sound to **1.2**.  Make sure to start the sound playing.  Play with different drop off factors and min distance values and see how it affects the sound in the room as you move around. <code python>
