Noise pollution

SOLUTION

INTRODUCTION

CAUSE

considered to be any unwanted or disturbing sound that affects the health and well-being of humans and other organisms.

According to the World Health Organization (WHO), it is one of the most dangerous environmental threats to health

The World Health Organization (WHO) defines noise above 65 decibels (dB) as noise pollution

noise becomes harmful when it exceeds 75 decibels (dB) and is painful above 120 dB

below 65 dB during the day and restful sleep is impossible with nighttime ambient noise levels in excess of 30 dB

TRAFFIC NOISE

AIR TRAFFIC NOISE

Human activities

INTRODUCTION

large number of cars and other road vehicles that have internal combustion engines are making road traffic noise a leading noise pollution source

the most significant source of noise in cities

traffic noise in urban areas has tremendously increased since the beginning of the century, primarily due to increased transportation of people and goods

CAUSES

Type of road vehicles

Driving style and driver behavior

is created during the process of compression and expansion in the engine, creates engine vibrations then emit noise

volume, speed, and capacity

VEHICLES

hook the horn unnecessary

90dB(A) – 115dB(A)

A car, in average, will have from 2 - 3 horns

INTRODUCTION

CAUSES

different types of engines

aircraft structure

as the sound which is produced from the movement of air between a solid body and air

landing gear, aircraft wings, and the flaps

The noise generated by these aircraft parts depends on different aircraft configurations

Turbojet engine

Turbofan engine

presented a big problem in the 1960s

noise source of such intake noise is the compressor blades

designed to reduce aviation noise levels

largest noise source was the compressor, turbine, and jet exhaust

Newer turbofan engine models have succeeded to reduce the aforementioned noise levels

INTRODUCTION

CAUSES

surrounded by gadgets and use them extensively in our daily life

Noise is at its peak in most of the social events

poor urban planning

social events

Congested houses, large families sharing small space, fight over parking, frequent fights over basic amenities

marriage, parties, pub, disc or place of worship

flout rules set by the local administration and create a nuisance in the area

selling clothes via making a loud noise to attract the attention of people

EFFECTS

household chores

In most of the developing countries, poor urban planning also plays a vital role

Gadgets like TV, mobile, mixer grinder, pressure cooker, vacuum cleaners, washing machine and dryer, cooler, air conditioners

cathering and night time

night parties continue with loud music and unnecessary noise made by the party mongers

restaurants, bars, and terraces spill outside

pubs and clubs

Humans

Animals

Noise Induced Hearing Loss (NIHL)

CARDIOVASCULAR ISSUES

CHILDREN

poor for memory, making it hard to study

CALLING MATES

UNDERWATER

rely on echolocation to communicate, navigate, feed, and find mates, and excess noise interferes with their ability to effectively echolocate

UNDERWATER

Ships, oil drills, sonar devices, and seismic tests have made the once tranquil marine environment loud and chaotic

Ships looking for deep-sea oil or gas deposits tow devices called air guns and shoot pulses of sound down to the ocean floor

Sonar, like echolocation, works by sending pulses of sound down into the depths of the ocean to bounce off an object and return an echo to the ship, which indicates a location for object

Sonar sounds can be as loud as 235 decibels and travel hundreds of miles under water

at low speeds, electric vehicles produce very small levels of noise

regular maintenance of vehicles and machines

choose your residential area as far removed from heavy traffic as you can

TROUBLE COMMUNICATING

severe headache and disturb your emotional balance

PSYCHOLOGICAL DISORDERS

stressed in their job and also often feel social pressure

mental system will be in addition challenged through noise pollution

not be able to handle all of this stress in a healthy way

hamper your sleeping pattern, thereby leading to irritation and uncomfortable situations

PEOPLE

ears need rest for 16 hours and even more to make up for two hours of exposure to 100 dB

Blood pressure levels, cardiovascular disease, and stress-related heart problems

put trouble and affect free communication between people

lead to misunderstanding, and you may get difficult understanding the other person

HEARING

soriented more easily and face many behavioral problems

animals may suffer from hearing loss, which makes them easy prey and leads to dwindling populations

Whales and dolphins are particularly impacted by noise pollution

unable to hear these calls due to excessive man-made noise

affects brain responses and people’s ability to focus, which can lead to low-performance levels over time

leads to lower response rates as well as making the mind dull

higher incidence of headaches, take more sleeping pills and sedatives, are more prone to minor accidents, and are more likely to seek psychiatric treatment
