Uzbekistan Passes Noise Law: 45dB Day, 35dB Night Limits

Tashkent, Uzbekistan (UzDaily.com) — Uzbekistan's Senate has passed a noise pollution law capping residential sound at 45 decibels by day and 35 at night, but lawmakers exposed an inconvenient truth during the vote: there is no mechanism for ordinary citizens to measure or report violations themselves.

The upper chamber of the Oliy Majlis approved the Law "On Protection of the Population from the Harmful Effects of Noise" at a plenary session, where debate quickly shifted from the legislation's merits to its practical blind spots. The law still requires a presidential signature before taking effect.

A Public Health Imperative — On Paper

Senator Oral Ataniyazova framed the legislation in stark epidemiological terms, citing the World Health Organization's classification of noise pollution as the third most dangerous form of environmental contamination, behind only air and water pollution.

The health consequences she outlined were extensive: sleep disorders, cardiovascular disease, hypertension, metabolic and psychophysiological disorders, fetal health impacts, cognitive impairment, dementia, and hearing loss. She also cited European Environment Agency data indicating that approximately 84% of learning disabilities in children across Europe are linked annually to traffic noise — a figure that carries pointed weight for a rapidly urbanizing Tashkent.

Nurmat Atabekov, First Deputy Chairman of the Sanitary-Epidemiological Welfare and Public Health Committee under the Ministry of Health, confirmed WHO findings that noise at 95 decibels constitutes a severe stressor on the nervous system and can cause deafness, while sustained exposure above 85 decibels produces comparably damaging health outcomes.

The Enforcement Gap

The session's most revealing exchange came when Ataniyazova pressed Atabekov on a specific WHO threshold: if exposure to 94 decibels for just 45 minutes per week is considered dangerous, how does a private citizen actually document that exposure — independently or through authorized channels?

No direct answer was given.

Atabekov instead noted that laboratories equipped to measure noise levels operate within each territorial division of the Sanitary-Epidemiological Committee, and said the agency intends to conduct proactive assessments and scientific studies — not merely respond to individual complaints. New measurement equipment is expected through projects funded by the Asian Development Bank and Asian Infrastructure Investment Bank.

By comparison, Ataniyazova pointed out that Belarus — whose noise law she cited as a reference — prohibits any activity generating sound above 40 decibels between 19:01 and 07:00, a stricter and more operationally defined standard.

Legislative Gaps Flagged

Ataniyazova did not stop at enforcement. She identified several structural omissions in the law: no formal role for NGOs, non-profit organizations, or civil society institutions in monitoring noise conditions; no embedded physical standards specifying minimum and maximum decibel thresholds in the legislative text; and no defined time-restricted periods in precise terms.

"Clear terms and definitions in laws are absolutely essential for ensuring legal certainty," she said, while clarifying that her criticisms did not diminish the law's broader significance.

What the Law Does Cover

In its current form, the legislation establishes general rules for protecting the population from noise, defines the authority of state bodies, sets permissible exposure norms, enumerates prohibited activities, and designates time periods during which noise violations are not permitted.

In parallel, the Ministry of Justice and Ministry of Finance have prepared draft documents on procedures for claiming compensation for harmful noise exposure. A scientific project is also underway at the Research Institute of Sanitation to conduct a comprehensive hygienic assessment of urban noise sources in a megacity environment — covering traffic, construction, vocal intensity, and aviation noise during aircraft takeoff and landing.

The law's passage marks a legislative first for Uzbekistan in noise regulation. Whether it translates into enforceable protection for residents will depend heavily on the secondary regulations still to be drafted — and on whether those regulations answer the question that went unanswered in the Senate chamber.
