The rule is 1-18.

The playing of music/sound effects shall only be permitted during pre-game, time-outs, intermission and post-game. The use of artificial noisemakers shall be prohibited.

From the NFHS website
The prohibition against artificial noisemakers, including but not limited to, megaphones, cowbells, sirens, 'clackers', cans with marbles or rocks inside, and varied other creative, albeit cacophonic, devices provides additional rules support for an increasingly serious problem.

From the NFHS Interpretations web page
SITUATION #6: The school sponsored cheerleaders wish to use megaphones as part of their cheerleading routines from the sidelines.
RULING: The new rule prohibiting artificial noisemakers would not apply to the cheerleaders in this situation. The megaphones would only be legal for the cheerleader’s use, provided they were being used appropriately. (1-18)

I hope that clears it up.
