During school hours, the school permits students to go onto the hillside of the campus located next to residential housing where groups of ten or more young people become a source of noise.

The Head-Royce School field, pictured here, is situated in a canyon bordered on one side by Lincoln Avenue and surrounded by residential homes on the remaining three sides. Noises from this playing field are magnified because of the canyon setting. While Head-Royce students playing games on the field can be loud and disruptive to the neighbors at times, such noises are part of everyday school noise. What concerns the neighbors is the use of air horns, and the use of commercial-size bounce houses requiring the use of industrial size -- and very loud -- blowers. Despite complaints from neighbors about the adverse impact of such noise, Head-Royce continues to use air horns and industrial blowers at times.
