Interactive Points - Sounds Attenuation Bug

Version: 1.7.16.0 and SU4

Frequency: Consistently

Severity: High

Context: Mounted from community or project.

Bug description:

The Acoustic Parameters inside the sound .xml are not being respected properly for any aircraft using interactive points for other parts of the aircraft as specified by the SDK, for example cargo doors, baggage doors, fuel doors, etc.

The sound.xml configuration clearly state these should be executed on EXIT types:

  <AcousticParameters>
    <Parameter Name="ReverberationPreset" ShareSetInside="rev_inside_default"/>
    <Parameter Name="Insulation_ExitClosed" Value="-26"/>
    <Parameter Name="Insulation_ExitOpen" Value="-10"/>
  </AcousticParameters>
[INTERACTIVE POINTS]
number_of_interactive_points = 6
interactive_point.0 =  Name:CockpitDoor #Properties:0.2, 4.503, -2.3703, 2.021, 0, 0, 0, 0, 0, 0, 0, 0, 0, -1
interactive_point.1 =  Name:FWDBaggDoor #Properties:0.4, 15.271, -1.902, 1.996, 1, 0, 0, 0, 0, 0, 0, 0, 0, -1
interactive_point.2 =  Name:CrewBaggDoor #Properties:0.4,15.271, 1.902, 1.996, 1, 0, 0, 0, 0, 0, 0, 0, 0, -1
interactive_point.3 =  Name:AftBaggDoor #Properties:0.2, -16.736, -1.572, 1.872, 1, 0, 0, 0, 0, 0, 0, 0, 0, -1
interactive_point.4 =  Name:FuelDoor #Properties:0.3, 2.017, 1.970, 0.653, 3, 0, 0, 0, 0, 0, 0, 0, 0, -1
interactive_point.5 =  Name:GPUDoor #Properties:0.37, -9.667, -2.621, 1.536, 4, 0, 0, 0, 0, 0, 0, 0, 0, -1

The interactive points above are all set correclty, main exit, fuel hose, ground power cable, cargo door, etc.

However despite of this, if any of the interactive points open (not the main exit, interactive point zero), the attenuation is gone, and you get the sounds of the core sim winds, etc. very loud in the cabin, even when the main exit remains closed.

This is a bug in the sound system, if I open my cargo doors, or GPU doors, or Fuel Doors, the sound should remain attenuated until the main door specified in the interactive points is the one that operates.

Repro steps:

DA62 suffers from the same, put lots of wind in the sim, open one of the secondary interactive points, and bang sounds are not attenuated anymore, just like the main door is now open.

Bump.. this affects lots of planes.. :slight_smile:

Hello @SimbolFSReborn

I’m not sure to understand what your repro is on the Da62.
Here, we can clearly hear that the insulation is reduced only when opening the main exit, not the cargo ones:

Test in my private package open the cargo doors, go inside and see how the attenuation is loss.

My cargo doors are interactive points, same with the gpu, fuel door, etc.

Mmmh, I was interacting with these through the InputEvents but they don’t change the interactive point position simvars so that explains it.
I see what you mean now, I’ll have this investigated.

Hello @SimbolFSReborn

I can confirm this applies to all interactive points regardless of configuration with the current design.
I will have this reviewed so can think of a way to offer more control on this.

Sylvain
