Impact of Noise Pollution on Health and Environment

The Nature of Noise

Advantages of Noise

• It does not cause permanent damage to the environment.
• It leaves no physical remains or exported waste.
• It is localized to a specific area.
• It ends immediately when the sender or source stops.

Disadvantages of Noise

• It is often the first pollutant detected by humans.
• It is highly disturbing despite having no cumulative physical presence.
• It directly affects human welfare and quality of life.

Health Impacts: Sound-Related Diseases

• Ulcers and digestive disorders
• Vascular and respiratory problems
• Systemic dysfunctions of the central nervous and endocrine systems
• Conditions affecting the eye
• Changes in blood chemistry
• Hypertension
• Hyperarousal
• Insomnia, anxiety, irritability, and stress

Sound vs. Noise: Perception and Intensity

The difference between sound and noise often depends on an individual's mood or the specific situation. Below are common decibel (dB) levels for various sources:

• Aircraft: 140 dB
• Electric Guitars: 90 dB to 130 dB
• Concerts and Nightclubs: 110 dB
• Heavy Traffic in Large Cities: 90 dB
• Headphones: 82 dB
• Average Rush Hour Traffic: 70 dB
• Normal Conversation: 55 dB
• Wind: 20 dB

Environmental and Intellectual Consequences

Environmental noise pollution blocks animal communication and interferes with the feeding habits of marine animals. For instance, engine noise often interferes with the frequencies used by whales.

The amount of noise one can endure without being bothered is often in inverse proportion to their mental capacity. It is frequently noted as a record of intelligence; noise can be a form of torture for intellectuals.

A noisy environment negatively affects language development and reading acquisition during periods of intellectual growth. It leads to decreased attention, increased errors, inaccuracies in responses, and a general lack of quality in performance. In daily tasks, it causes a loss of concentration and memory.

• In everyday life, we are exposed to noise between 35 and 85 dB, with 85 dB being the safety limit.
• Noise causes strain in relationships, stress, moodiness, irritability, and inattention during dialogue.

Harmful noise sources: Loud recordings, motor transport, aircraft, and factories.

Noise Mitigation and Global Standards

Developed Countries

• Apply advanced technology and strict laws to reduce noise.
• Prioritize quiet public transport systems.

Ways to Fight Noise

• High-Cost: Reducing noise levels at the original source.
• Economic: Increasing the distance between the source and the receiver.
• Isolation: Creating discontinuities in sound pathways.
• Barriers: Placing porous obstacles between the transmitter and receiver.
• Silencers: Implementing sound-dampening technology on acoustic bridges.

Legal Framework: Ordinance 12032

Prohibitions

• Causing noise nuisances that result in prejudice or inconvenience.
• Noise caused by stationary or mobile sources that disturb public tranquility.
• Vehicles operating without a muffler, unnecessary use of horns, excessive throttling, or engine testing/reheating.
• Restricted Hours: Specific regulations apply between 22:00 and 06:00 hours.
• Unauthorized works in public places.
• The use of bells, amplifiers, and similar devices outside of churches.
• Pets that may cause a disturbance to neighbors.

Measurement and Zoning Standards

In rooms where noise levels grow dramatically, measurements should be taken from the middle of the floor at a minimum height of 3 feet to capture the audio issue directly.

• Noise sources must not be located within 100m of schools, churches, and hospitals.

Public Access Venues

• Local Game Venues: Maximum limit of 65 dB.
• Venues with Acoustic Isolation: Maximum limit of 90 dB.
