Portal falling sound in Gmod?

Anyone who has played portal will know when you fall from a high platform you hear that wind sound you hear when you fall. This feature will be cool because it will be nice if i fall off the building in construct and i hear PFFFFFFFFFFFFFFFFFFFFFFFF. Make it more realistic, the only problem i see is that if you’re in a ship you will hear the falling sound falsely, unless someone makes it that if you’re sitting you don’t hear it. Thanks for listening!
