Please adjust so that the ringing of these bells can be heard at an adequate distance
There are other bells in the game (e.g.: Land_BellTower_01_V1_F), the audible distance is 250 meters, maybe it’s worth choosing this value? Or less because visually the Livonia bells are smaller in size
see video

1. CfgAnimationSourceSounds → SmallBellSound → RingTheBell
2. CfgAnimationSourceSounds → TinyBellSound → RingTheTinyBell

But

if we make the audibility distance e.g. 150 meters then at a close distance the sound will be unbearably loud. It might be worth lowering the volume value too.
Or, note that there are several problems with sounds from animations (see T179776) the problem could be in "CfgAnimationSourceSounds"
