I recently moved my horse to a new barn that has a lot of echos. The previous barns my horse has lived in did not have this problem. The configuration of the barn is also not helping because the stalls are on the other side of a wall of the indoor arena but it is not a complete wall so that the sound from the arena can be heard in the aisle and the sound from the aisle can be heard in the arena. Whenever somebody has a horse in an area of the barn my horse cannot see he gets very frightened and will not calm down. I have been working with him but it has been a few weeks and he is still very scared. Does anyone have any ideas that I can try?
