# Shared Attenuation<no value>
The `WwiseSampleProject` contains several sharesets in the project that can be used for attenuation, or as references for you to create your own attenuation sharesets.

    alt="Wwise Attenuation Sharesets" >}}

When you create a custom shareset, we recommend that you do *not* exceed the clipping distance values shown below in your attenuation shareset (the *Max Distance* parameter in Wwise):

-   **Player Aircraft**: clipping distance is set up to 10000 meters
-   **AI Aircraft**: clipping distance is set up to 5000 meters.

 

If you are not familiar with **spread** and **focus** attenuation, you will find all the resources in the Audiokinetic on line documentation:

-   [Wwise Help - Panning on a 3D Configuration](https://www.audiokinetic.com/library/2017.2.10_6745/?source=Help&id=panning_on_3d_config)

 

The tables below outline the sharesets available in the `WwiseSampleProject`.

|--------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `aircraft_player_outside_piston_50m`             | This shareset could be use as a generic shareset for sounds that are nor engine sounds. Max attenuation distance is 50m.                                                                                                                                          |
| `aircraft_player_outside_piston_1500m_exhaust`   | This shareset is suitable for **exhaust** sounds from outside viewpoint, on small piston aircraft. As the engine node is facing forward you would need to setup your exhaust sounds to `ConeHeading=180` in the `sound.xml` so this way it will facing backwards. |
| `aircraft_player_outside_piston_1500m_propeller` | This shareset is suitable for **propeller** sounds from outside view, on small piston aircraft. You don't need to set up `ConeHeading` so the node will keep its default value (`ConeHeading= 0` and facing forward)                                              |
