Pollution is one of the main concerns, the world is dealing with amidst all the problems and issues. However, most of the time, it is air pollution and water pollution that is spoken about. The limelight may not be on Noise Pollution but it also has tremendous negative effects. Noise is a word that has been coined from the Latin term Nausea. Nausea is a health issue that causes a sensation of vomiting and dizziness. Coincidently high pitch noise can result in sickness and even permanent loss of hearing. So, we must take measures for noise pollution prevention.
Introduction to Noise Pollution Prevention
Noise or sound is only bearable to the ears of any living creature up to a certain level. Beyond that, it can cause massive irreparable damage. Researchers have proven the fact that excessive noise can cause changes in biodiversity also.
The intensity of the noise can vary, hence the resultant action also varies depending on the level of noise pollution. To understand how noise Pollution prevention can be successfully implemented one needs to know in-depth about the science behind Noise.
Sound vs Noise – The Correct Interpretation
This is one of the most confusing aspects. Sound and Noise might be related, but they are two different entities. Sound is defined as the form of energy that is transmitted using pressure changes.
Further, musical instruments, human voices are various sources of sound.
Noise in simple terms is called unwanted sound. Anything that is uncomfortable to hear or causes unpleasant sensations is noise. Moreover, the interpretation of when a sound is unpleasant or when it can be called noise is relative.
Based on the time, place, intensity, and length, the deciding factor whether it is noise or sound can vary.
Measurement of Sound
Alexander Graham Bell was the first inventor who coined the term Decibels (dB) as the unit of measurement of sound.
The normal sound a human ear can perceive is generally 1 Decibel (dB). Further, we consider anything over 30 dB as noise pollution. In addition, while if the sound level goes beyond 130 dB, it is a health hazard and can cause irreparable damage.
Types of Noise Pollution
Primarily there are two main reasons for Sound Pollution that can occur. They are:
- Man-Made Noise Pollution – These include a wide range of noise disruption that occurs as a result of man-made noise like, vehicles, honking, Air traffic, construction, fights, loud music, and various other household noise.
- Environmental Noise Pollution – These are noise emitted as a result of environmental issues like Earthquakes, thunderstorms, Volcanic eruptions, howling of animals, etc.
Primary causes of Noise Pollution
Noise Pollution can occur as a result of numerous causes like:
- Increased Industrialization
- Increased Construction activities
- Social Gathering
- Traffic Congestion and honking
- Air traffic noise
- Natural Disasters
Effects of Noise Pollution
Noise Pollution can cause numerous problems that are irreversible and irreparable at the same time. The need for Noise Pollution Prevention is alarmingly arising because of these effects. They are:
- Hearing Impairment
- Mental health Issues
- Insomnia and other Sleep Disorders
- Cardiovascular ailments
- Performance issue in biomedical devices like Pacemakers
Methods of Noise Pollution Prevention
We can prevent noise pollution if we implement a few regulations and rules strictly. These rules include:
- Controlled traffic noise emission
- Limiting the volume of music and mics in social gatherings
- Planting a large volume of trees to create a natural sound buffering surrounding
FAQ on Noise Pollution Prevention
Question 1: What is noise pollution prevention?
Answer 1: Noise Pollution Prevention measures we take to prevent excessive noise. Thus, one of the most economical and long-term solutions to Noise Pollution prevention is planting a large number of trees. Because they are a natural source of Sound Absorption.
Additional implementations include Vehicular maintenance, maintaining an optimal volume, using noiseless appliances, etc. Moreover, noise Pollution Prevention can help in reducing numerous health issues from occurring.
Question 2: What are the 4 main causes of noise pollution?
Answer 2: The main causes are:
- Constructions and Mining
- Celebrations and events with loud open-air music
Question 3: How is noise pollution harmful to humans?
Answer 3: Noise-Induced Hearing Loss (NIHL) is one of the primary issues caused due to excessive noise. Further. other health issues that can elevate due to Noise Pollution include Increased Blood Pressure, Abnormal Heart conditions, Insomnia, and Psychological Stress
Question 4: Which are the top 5 noisiest cities in the world?
Answer 4: The noisiest ones are:
- Guangzhou, China.
- New Delhi, India
