Same for my JV experience in NoVA - and I believe Varsity was similar.That's not been my experience in NOVA. At the Class 6 state championships, the VHSL announcers played random walkup songs for every player and played them so loud that our pitcher often had to wait for the song to end to get the pitch signal from the coach because she could not hear him yelling from the dugout. Every single game we played this year had walk up songs for the home team and music between innings.
2 years ago we attended USSSA Nationals in Nashville - one team used drumsticks on bucket lids. I checked, and at the time could not find any USSSA rule against noisemakers. So they may be exception to the other rulesets.
