I only tested it between Android and Windows, but this appears to be a global issue.
In Java Edition, if you use a goat horn, the produced sound can be heard up to around 100 blocks away. Making it actually useful for calling out pvp raids or simply trying to get a friend's attention from a distance.
However, in Bedrock, this range is greatly reduced to that of 5 blocks, making the goat horn entirely useless.
The goat horn has been this way since it was added to the game. Functional in Java, broken in Bedrock.
