Loud music is music that is played at a volume that disturbs others, such as neighbors or bystanders, who do not wish to hear the music, at least not at the same volume, or that is otherwise viewed as a nuisance to the public. It may include music that is sung live with one or more voices, played with instruments, or broadcast with electronic media, such as radio, CD, or MP3 players.
Playing loud music that can be heard from outside of the property from where it is being played (such as a house, apartment, hotel room, or motor vehicle) is considered to be rude by many people and societies. Among those opposed to the practice, it may result in the loss of respect and possible legal action. But in certain contained settings, such as clubs or concerts, music is often played very loudly, but is viewed as acceptable.
The term crime does not, in modern times, have any simple and universally accepted definition, but one definition is that a crime, also called an offence or a criminal offence, is an act harmful not only to some individual, but also to the community or the state (a public wrong). Such acts are forbidden and punishable by law.
