Artificial noisemakers

[FrankHtown]

Doing a playoff game...small gym..home team supporters have "thunder sticks"...those annoying things you bang together. Visiting coach asks us to ban them during play, especially when their team was shooting free throws, for being "artificial noisemakers." I didn't have a good reason to object, so game management made an announcement. Of course home team supporters booed a little bit, but complied. Do "thunder sticks" fall under "artificial noisemakers" as opposed to, for example, an air horn?
