The bug
In Bedrock, sounds can be in either OGG or FSB format. Almost all vanilla sounds are FSBs for some unknown reason, unlike Java. The problem is that FSBs do not fade with distance correctly. The falloff is too slow, so at the edge of the sound's radius, it abruptly becomes inaudible. OGGs correctly become quieter and quieter until they are no longer audible at all. To explain visually:
White = audible, red = inaudible. FSBs have a clear and obvious cutoff point at 16 blocks, OGGs fade naturally.
This affects basically every vanilla sound in the game.
How to reproduce
Download and open the attached world. The command block is playing an identical sound file – one as OGG and one as FSB. Hold the feather to hear the OGG, and the brick to hear the FSB. Walk towards and away from the source of the sound to hear how it changes with distance.
Expected result
The sounds should be indistinguishable. Both should fade out to inaudible at the edge of the circle.
Observed result
The FSB is louder in general, and does not fade out at the edge of the circle – it cuts off abruptly.
