I work as Aircraft B2 Engineer for an european Airline with a rather large A340 fleet... 😉

One thing I REALLY miss concerning the soundscape of your A340 ist that VERY LOUD "clonk" sound of all the relays and breakers switching when you turn on EXT Power on ground from the cold and dark state.

You must have surely heard this one during your research on the real aircraft and know what I mean?! Can you please add this one. It's such a typical sound when powering on aircraft...

• At cruise, the sound is far too quiet, there is not much of a roar from the engines, or wind. There should be some sort of environmental wind sound that should more or less drown out the engines anyway.
• The whine from the engines isn't quite right. The 4 CFM56's are quite screachy as they accelerate past 40% and up to takeoff power. You can quite regularly hear them slightly out of sync making some cool harmonies!
• Buzzsaw sound is too distant, it sounds as if the aicraft is 2KM away, should be more buzzy and intense.

INTERIOR:

• The CFM56-5's on the A320/340 accelerate very slowly up until 30-40% N1, after that they accelerate very rapidly and are responsive especially when launching straight to their takeoff setting. They also have a quirk where they drop pitch ever so slightly when you advance the throttles to stabilize the engines at around 50% N1, as if they overshoot ever so slightly and bring themselves back to their assigned power! Would be nice to have the sounds adjusted to match this. 
• The whine sound in general just doesn't sound like a CFM56, it needs to be more intense and audible.
• Buzzsaw intensity is off internally also, it should have much more of a growl to it. 
• The range of pitch is too low and limited, as if the engines are dramatically derated. On the iniBuilds A340, the buzzsaw isn't really audible until about 90% N1. An A343 at TOGA will have mostly exceeded the buzzsaw range, which starts in the high 70's/low 80's N1. For example: 
• The distinct sound that you get when you advance the throttles is missing entirely, inside and out. It's like a deep roaring sound that's independant of the engine RPM and doesn't change pitch. It's caused by compressor bleed valves being opened as the engine accelerates.
• The transition from cockpit to cabin is abrupt. The cabin is far too quiet, engine sound and environment sound.
• No 3D internal engine sounds. The sound sitting behing the wing should be very different to sitting ahead of the wing, as is sitting over the wing.
• Ground roll sound is missing. Such a shame after how great it is on the A350!

I'm sorry if I seem pedantic... I just really like airplane noises 🙃

I recently purchased the a340 and am loving it. However I noticed while switching views into the cabin that there was a really disproportionately loud sound in the cabin. I discovered it was the fuel pumps causing the noise, but also realized that if I walked the camera out of the cockpit door and into the cabin and then switched to a cabin view, the loud fuel pump sound went away. I'm not very technical but I would assume it has something to do with the spatial audio? I've attached a video to this post demonstrating the difference in sound, I think its easier to just see my issue. I also notice that the same thing occurs in flight with the environmental noise (extremely loud cabin sounds when switching views to the cabin from cockpit, but normal sound when moving the camera out of the cockpit into the cabin). I'm using chaseplane so I tried disabling it, but still had the same problem. This is the only plane I have that has this issue. I hope it's something on my end that's causing this, but I'm out of ideas. Any help is much appreciated, Thanks.

The vibration/turbulence sound the speedbrakes generate, continue until after landing when reversers are off but SPD BRK is still armed and thus deployed. Theoretically, this sound should become less audible the slower the aircraft becomes and should not be heard at all after landing or when the aircraft is taxiing.

Thanks, Daniel

I've noticed that with the latest update (1.0.1), the GPWS is not announcing certain callouts, such as '90', '80', '70', and '60'.
All other callouts are working fine.

Any ideas?

Thanks !

- Switch on all fuel pumps

- Move to an overwing cabin view - you can clearly hear the pumps

- Switch to outside view

- Switch back to overwing cabin view - the pumps are no longer audible. If you cycle the pump switches in the cockpit, the sounds will return.

Thanks all!
