Definition
In law, noise is not defined as a freestanding legal concept but functions primarily as a category of harm within the law of nuisance. Noise becomes legally cognizable when it unreasonably interferes with another person's use and enjoyment of property, rises to the level of a public disturbance, or violates a statutory or regulatory standard. The legal question is never whether sound exists, but whether the sound, in its character, volume, frequency, and context, crosses the threshold of legal injury.
1. Private nuisance context: Noise constitutes an actionable private nuisance when it substantially and unreasonably interferes with a neighbor's or adjoining landowner's use and enjoyment of their property. Reasonableness is assessed by reference to the locality, the time of day, the nature of the surrounding land use, and the sensitivity of the complaining party.
2. Public nuisance context: Noise affecting a community, neighborhood, or class of persons — such as persistent industrial sound, amplified music in public spaces, or continuous commercial noise — may constitute a public nuisance abatable by government action or, in some jurisdictions, by private suit where special damage is shown.
3. Regulatory context: Municipal noise ordinances, zoning codes, and environmental regulations establish quantitative or categorical standards (decibel levels, time restrictions, land-use classifications) that define noise violations independent of common-law nuisance analysis.

Common Language
Modern common usage (Wiktionary): Various sounds, usually unwanted or unpleasant; also any signal corrupted by random fluctuation.
Historical common usage (Webster's 1913): Sound of any kind; especially loud, confused, or senseless sound; clamor; din; also general talk, rumor, or report.
Editorial note: In ordinary usage, noise is descriptive — it identifies a type of sensory experience. In law, the common meaning is a necessary starting point but legally insufficient. Whether a sound qualifies as legally actionable noise depends on relational and contextual factors — who is affected, where, when, and to what degree — that the common definition does not address. A sound that is noise in ordinary English may be entirely lawful; a sound that meets regulatory decibel thresholds may be actionable even if most people would not perceive it as unpleasant.

Common Confusion
Noise is frequently treated as synonymous with nuisance in casual legal usage, but the two are not interchangeable. Nuisance is the legal doctrine; noise is one possible basis for a nuisance claim. Not all noise is a nuisance, and not all nuisance involves noise. Researchers should also distinguish between common-law nuisance claims grounded in noise and statutory or regulatory noise violations: the standards, remedies, and procedural postures differ materially.

Why It Matters in Research
Bouvier's entry for NOISE directs researchers immediately to NUISANCE and INJUNCTION — a spare but accurate compass. This means historical legal research on noise disputes will be found almost entirely within nuisance materials, not under a standalone noise heading. Researchers working in the Law Mind corpus should search nuisance doctrine broadly and look for noise as a factual predicate rather than a doctrinal category.
Key navigational points:
The common-law noise cases developed primarily in the context of industrial activity (mills, forges, slaughterhouses) adjacent to residential property. Early cases frequently turned on locality doctrine — the same sound that constituted a nuisance in a residential district might be entirely permissible in an industrial one. This locality analysis persists in modern nuisance law but is increasingly supplemented or displaced by regulatory standards.
Injunctive relief is the historically preferred remedy for noise nuisance, reflecting the ongoing, noncompensable character of the harm. Damages are available but have traditionally been harder to quantify. Researchers examining equity jurisdiction materials will find noise cases among the most litigated categories for injunctions.
The regulatory turn in noise law is a twentieth-century phenomenon. Before zoning codes and environmental noise regulations became widespread, noise disputes were exclusively common-law matters. Historical sources from the nineteenth century and earlier will reflect this: expect pure nuisance analysis with no reference to decibel standards, permit requirements, or administrative enforcement.
Municipal ordinances addressing noise — nighttime disturbance, excessive sound from commerce or entertainment — overlap historically with public order law and the law governing night-walkers and disorderly conduct. Anderson's entry, which redirects under a neighboring headword, reflects this older connection between nocturnal noise and breach of the peace.
Researchers examining constitutional dimensions of noise regulation (First Amendment challenges to sound ordinances, takings claims arising from airport or highway noise) will find those materials outside historical dictionary sources and within twentieth-century administrative and constitutional law.

Historical Dictionary Support
Bouvier's Law Dictionary treats NOISE as a pure cross-reference: "See NUISANCE; INJUNCTION." This is historically consistent with the treatment of noise as a factual predicate rather than a doctrinal category. Bouvier's approach correctly signals that the substantive law lives elsewhere and that researchers should not expect a developed doctrine under this heading.
Anderson's Dictionary of Law does not carry a direct entry for NOISE in the provided source material; the neighboring entry for NIGHT-WALKERS reflects the older connection between nighttime noise and public order, touching on the peace-disturbance tradition from which some noise regulation descends.
Webster's 1913 definition — emphasizing clamor, din, loud or continuous talk, and report — captures the sensory and social character of noise that courts have historically weighed in nuisance analysis. The phrase "senseless sound" is particularly telling: early nuisance courts often asked whether the noise served any legitimate productive purpose as part of the reasonableness inquiry.
Neither historical dictionary source addresses the regulatory dimension of noise law, which is expected given their publication dates. Researchers should treat historical sources as reliable for common-law nuisance analysis and supplement them with twentieth-century administrative materials for regulatory noise standards.

Jurisdictional Note
Common-law nuisance standards for noise vary by jurisdiction, particularly in the weight given to locality doctrine versus plaintiff sensitivity. Regulatory noise standards are highly local: municipal ordinances differ substantially in permissible decibel levels, time-of-day restrictions, and enforcement mechanisms. Federal noise regulation (primarily through the Noise Control Act of 1972 and related EPA authority) has had limited preemptive effect, and many federal noise programs were defunded or curtailed in the 1980s, leaving primary regulatory authority with states and municipalities.
