After the talk, they alerted the community via Facebook and apologized for the noise:

"Apologies to anyone in the Haydonleigh area who may have been disturbed by our sirens yesterday morning – the PCSOs were at the Primary School having a very important debate with the new Reception Year children about whether they go nee-nah or woo-woo."

The students decided the "nee-nah" vs. "woo-woo" matter with a vote:

Nee-nah V Woo-Woo, the results are in!The perplexing issue of nee-nah or woo-woo has gripped not only the nation but...
