The most effective detail to add to paragraph 3 would be:
"A few residents have complained that their health has been affected by being woken at night by loud noises."
This detail strengthens the argument of supporters by emphasizing the negative health impacts that excessive nighttime noise can have, providing a more concrete reason for needing the ordinance. It directly addresses the concerns of those advocating for the noise restrictions and supports their claim about the need for a peaceful environment during nighttime hours.
