The bounce houses do make some noise during operation, because they are kept running by the air blower that needs to be kept on all the time, plus the various sounds made by the children bouncing on it, the latter is more noisy.

Generally, the noise of the blower on a smaller size castle(such as 12ft x 12ft) is similar to that of a vacuum cleaner. A slightly larger castle or a large obstacle requires many blowers, and the sound will be louder.

So if you think it noisy, it’s best to move the bouncy castle a little away from the crowd. This brings some peace to guests who are not on the castle.

However, in order to supervise the safety of the children, you also don’t want the castle to be too far away, otherwise the children won’t be able to play on it for too long. If you are hosting a bounce house birthday party for your child, noise is not the biggest problem, the biggest is still safety.
