What type of noise is termed as 'unreasonable' under Penal Code 415?

Under Penal Code 415, the term 'unreasonable' is applied to noise that is considered a disturbance to the peace, which predominantly includes maliciously loud disturbances. This type of noise typically disrupts the normal tranquility of a neighborhood or environment and can involve actions that are intentionally harmful or disruptive to others' peace. The emphasis on 'maliciously loud' underscores the notion that this behavior is not only disruptive but also done with intent to disturb or annoy others.

In contrast, soft whispers, musical tunes at a reasonable volume, and normal conversations typically do not rise to the level of a disturbance that would be classified as 'unreasonable.' These forms of noise are generally acceptable in most environments, as they do not intrude on the peace and quiet of a community. In the legal context, 'unreasonable noise' often involves loud and disruptive behavior that is out of proportion to what would be considered normal, peaceful activities.
