v21.33

Replaced the default short Boeing engine sound loop (which doesn't follow the plane) for takeoffs and landings with general airport runway ambience.
This sound is softer and has a higher distance range so it's audible within the airport area and won't feel unrealistic when a plane isn't present.

Extended range and added extra layer for the sound of Boeing 737 taxiing.
3D positioned default lift axle sound to be closer to the axle (correct me if it should be closer to the engine).
Removed 1 air brake sound variant.
Reduced some sound file sizes without quality loss.
Reduced cooldown for air brake sounds.

v21.32

Subtle variations implemented for the default light switch sound.
Slight reduction in volume for PrePass transponder sounds for weigh stations.
Reduced file size without quality loss.

Updated mod description

v21.31

Get ready for plane spotting! Realistic distant and closeup sounds have been added to the flyby animation of the Boeing 737.
It will also sound different if it flies directly above you and will sound a tiny bit louder at night due to the effects of refraction.

Reduced helicopter sound file size without quality loss.

For modders: reefer.soundref file is now deleted.
reefer_up.soundref and reefer_down.soundref will be used instead for the respective trailer brace sound event (applies to reefer trailer sounds).

v21.30

Reduced sound volume of helicopters, after finding out most fly way too low in the game and would be too frequently annoying at its previous volume.

v21.29

Slightly improved sound quality of air brake sounds.
Updated play probabilities for each air brake sound.
Eliminated some caveats such as the need to restart the game for reefer trailer sounds (experimental feature for modders).

For modders: reefer.soundref file is now deprecated and will be deleted on release of Sound Fixes Pack v21.31.
reefer_up.soundref and reefer_down.soundref will be used instead for the respective trailer brace sound event.

v21.28

Added sound bank for reefer trailers for modders to use (experimental feature).

v21.27

Slight improvement in playback quality for thunder sounds.
Raised volume for thunder sounds slightly.

v21.26
