If you set off a firecracker in 3, 5, 7, etc. dimensions, then you’ll see and hear the explosion for a moment, and that’s it. If you set of a firecracker in 4, 6, 8, etc. dimensions, then you’ll see and hear the explosion intensely for a moment, but will continue to see and hear it for a while. For light the effect would be fairly subtle, except for extremely long-distance effects, like somebody reflecting a bright light off of the moon. You probably wouldn’t notice the effect day-to-day. However, it would ruin the experience of sound. In 4 dimensional space the firecracker, even in open air, would sound like thunder; loud at first, and leading into a drawn out boom. It may not even be possible to understand people when they speak.
