Cause Of Noise Pollution

There are many causes of noise pollution these days, below are the most common ones that people encounter.

  1. Due To Transportation

Currently outdoor means of transport such as motorcycles, trains,… are increasing and being used a lot. Increasing traffic density on the road causes noise pollution from engines, sirens and brakes.

Furthermore, airplanes are also a vehicle that cannot be ignored. The noise it generates has a much higher level of noise pollution than other vehicles. When you are in a residential area near an airport, you will experience a very high amount of noise at the time of the plane landing and taking off.

  1. By Production And Business Establishments

The second cause of the noise is the noise generated from industrial zones. These noises are caused by the operation of machines and construction works. When the machines are working at the same time, the noise will be extremely loud, making you uncomfortable when living nearby.

  1. Due To Construction Activities

The use of construction machinery is now quite popular. This is part of the loud noise. Machines such as bulldozers, excavators, excavators, concrete mixers,… have caused extremely annoying noises.

For example, in the building where you are building and repairing the road, they will use the excavator to dig the road to make a very loud noise, not only that but also can damage the facilities in your house.

  1. Due To Daily Life

In today’s life, you will easily detect sounds from everyday life. These noises are usually screaming, loud music, phone, music player, etc. The sound is usually not too loud but it happens often, it can affect. hearing. These are often unavoidable in the urban rhythm of living with many people.

  1. Other Reason

Some other sources of noise pollution include: Protests, public events, sporting events. Sources from animals such as the barking of dogs, pigs, and ducks coming from livestock households. Noises from neighbors’ houses, such as loud music, screaming, mower noise, accidental alarms, fireworks. Especially, the sound of cell phones in public places, including classrooms and conferences, is also a source of noise pollution.

Harm Of Noise 

Below are the dangers of not insulating your room and exposure to excessive noise that could cause you.

  1. Brain Damage And Hearing Loss

The brain and ears are very important parts of the human being. When they are damaged by noise, various damaging effects will occur.

When high-noise sounds occur, unnecessary noise waves enter the ear, disturbing the fluid that aids sound transmission between the ear and brain.

This can destroy the tiny signalling cells in the ear, damaging the process of transmitting sound to the brain, leading to hearing loss. Moreover, this can jeopardize children’s memory and reading ability.

This happens when 50% of the communicating cells are damaged. When hearing damage, I need to use hearing aids to help me hear better. 

  1. Increased Risk Of Cardiovascular Diseases

Years of exposure to noise pollution increases your chances of developing heart disease. High noise levels increase heart rate and cause blood vessel constriction, leading to heart attack and increased blood pressure.

For example, the music emanating from the speaker that we often see at weddings, festivals or other parties, the sound will create vibrations for every surface, as well as the human body, thus vibrating your heart, causes damage to your heart.

If you are exposed to noise for more than 8 hours a day, it can make your illness worse, especially for those who have heart disease.

  1. Psychological Disturbances

Once you get used to the noise, it can lead to serious psychological disturbance. Often we cannot realize it and it becomes a part of our life. It will make you easily irritable, anxious, irrational when making decisions, sometimes feeling uncomfortable all day.

In the worse case, your life will become so stressful that you will be detached from society, ineffective at work due to lack of concentration, emotional instability, and decreased confidence in communication. If you are not discovered in time, you will develop a bad personality.

  1. Decreased Sleep Quality

A good night’s sleep will help you feel refreshed, comfortable and rested after hard working days. However, living in noisy areas will result in poor quality sleep. It will make you fall asleep, startle easily, lack sleep, and have difficulty falling asleep.

The consequences of not getting a good night’s sleep are making you bored, tired, and sometimes even giving up on energy-draining activities.

Not only that, but it can also increase the risk of cardiovascular diseases, reduced memory, ageing skin, negative effects on emotions and sometimes affecting the brain if you don’t get enough sleep.

  1. Affecting Communication

When you are communicating in a noise-polluted environment, this is useless, and the noise drowns out your voice, preventing your listeners from hearing what you are saying clearly.

Working with noisy machines, for example, directly affects your social life and makes your day seem longer than it really is.

  1. Affects The Structure Of The House

When loud noises are heard, vibrations are generated to the surfaces. This vibration can damage your room structure such as tilted rooms, cracked walls, …

For example, noise caused by road repairs. When the road repair machine is in operation, it will cause noise and the engine will cause strong ground vibrations so your home may also be affected.

Ways For How To Soundproof a Room from Outside Noise Effectively

Way 1: Change The Surface

  1.  Install Soundproof Curtains Or Thick Curtains
how to soundproof a room from outside noise

The use of these soundproof curtains not only helps your home to reduce noise but also can help your room become more unique and beautiful. This can be the optimal choice for families who are renting a house or apartment because they may not be able to change rooms or replace the whole door.

If your house has been built with soundproof walls, the curtain will enhance its effect more.

  1. Paint surface coating absorbs sound
how to soundproof a room from outside noise

You can go outside to building materials stores to ask them what paints absorb sound. Follow the paint instructions on the box, but most of them will be the same as normal paint, but the paint will be thicker.

  1. Apply Styrofoam soundproof stickers
how to soundproof a room from outside noise

Some acoustic panels are manufactured with a single layer of glue. Use 3M spray glue to attach the panels to walls and ceilings if they don’t already have adhesive. You can cover all or part of the surface, depending on how much sound insulation you want. This will reduce the ‘noise’ emitted from the room and produce a better sound, especially when you use the room as a vocal practice.

Use soundproof panels with a main composition of fiberglass, coated with a thin layer of Mylar with holes. This type of soundproof material has the highest absorption of sound compared to most other types, but also the most special and expensive. This product is worth your investment more than any other product in the market.

You can find 3D soundproof foam stickers from material stores or on e-commerce sites. Soundproof foam is composed of 2 layers, the base layer and the surface layer, in which the soundproof layer is made of vinyl or foam.

You can measure the door size and then cut the sponge to that size with a knife. Use the glue to stick the foam on the door.

  1. Use Bookshelf
how to soundproof a room from outside noise

You can make walls thicker and make better sound insulation with bookshelves. Cover the wall with shelves of books and books to create an effective sound barrier. In addition, your room will become a very beautiful library room.

Way 2: Install The Gaps In The Room 

Step 1: Check For Openings With A Flashlight

how to soundproof a room from outside noise

Turn off all the lights on both sides of the door, then ask someone on the other side of the door, and close the door. On this side, you use the black pin around the door and on the surface of the door, then record the places where light passes. Don’t try to fix all the gaps on the door, but instead, choose the largest, largest gaps for improvement.

Step 2: Fill The Openings In The Door

how to soundproof a room from outside noise

Use a glue gun and fill in any gaps you just discovered. Then wipe off any excess. Filled spaces absorb sound and prevent it from passing through your door.

Step 3: Installation Of A Door Sill Or Door Sweep

Check to see if there are any gaps between the door and the floor. If the gap is large enough, choose to install Door Sill or Door Sweep so that the sound does not pass through the place. In addition, you should also install rubber gaskets around the door to limit the sound passing through the junction between the wings and the frame.

Step 4: Place The Rug In The Entrance To The Door

how to soundproof a room from outside noise

If the door opens on a tile or parquet floor, a very annoying sound will be heard. Minimize these sounds by placing a rug in the entrance area, which helps you keep the house clean while absorbing the sound coming from under the door.

Step 5: Replace The Glass Panels

how to soundproof a room from outside noise

If your door is decorated with glass, choose tempered glass panels or laminated glass to make it difficult for sound to move from one space to another. On the other hand, you should also choose frosted, non-transparent glass panels to ensure the privacy of family members.

Way 3: Install Of Soundproof Doors

how to soundproof a room from outside noise

Soundproof doors may be the best option for effective sound insulation. Currently, on the market there are many different types of soundproof doors and each type has its own advantages and disadvantages, so depending on your needs, there is the most reasonable choice.

Way 4: Using Soundproof Texture

This approach is very effective but will be a bit complicated if you do it by yourself. I recommend that you need about 2 to 3 more people to help.

Step 1: Use Thick Material

how to soundproof a room from outside noise

The thicker and denser the material, the better it absorbs sound. Consider using drywall 1.6cm thick instead of thinner.

If you want to renovate the existing wall then build the basic wall structure and attach it to the surface, connecting it to the existing studs. Cover with a new plasterboard.

Step 2: Separate The Two Layers Of The Wall

When sound enters a material layer, part of the energy is absorbed and some of the energy is reflected back. Increase this effect by building walls from two layers of drywall or plaster, the greater the distance between them, the better. This is called the method of building a removable wall.

Step 3: Locate Studs

how to soundproof a room from outside noise

Most walls have a row of studs that connect the two layers together. The sound easily passes through these studs, largely ruining your sound insulation effort. When building a new wall, you should choose one of the following methods of riveting:

  • Catch two rows of studs, each catch on each inner side. This is the best method of sound insulation but requires enough space to allow space between two rows of nails.
  • Attaching rivets in a zigzag means rotating each rivet on the inner sides.

Step 4: Use Soundproof Clips Or Troughs

how to soundproof a room from outside noise

They are placed between the rivet and the drywall, adding sound insulation to the wall. There are two main options:

  • The soundproof clamp is the most effective method, absorbing sound with heavy rubber parts. Fasten them to the wall with rivets, insert the chute and then catch the drywall on the clamp chute.
  • Elastic gutters are resilient metal troughs designed for sound insulation. Attach the chute to the wall with studs, then attach the drywall to the trough with corner screws. This method increases high-frequency sound insulation but reduces low-frequency sound insulation.

Step 5: Insert The Noise-Proofing Compound Into The Gap Between The Wall

how to soundproof a room from outside noise

This material can convert negative energy into heat. You can use damper compounds between layers of walls, floors or ceilings. Unlike other methods, this absorbs low-frequency sounds. The damper compound is therefore well-suited to suppressing music with bass, and for soundproofing in home cinema rooms.

On the market, this product is also known as an anti-noise elastomeric glue or adhesive. Some types need days or weeks of “maintenance” to maximize their performance.

Step 6: Sound Insulation With Other Materials

how to soundproof a room from outside noise

Soundproof with other materials. The soundproof compound is one of the soundproofing materials that are suitable for all purposes, in addition, there are many other soundproofing materials such as fibreglass or soundproof foam.

Step 7: Seal The Gaps With Soundproof Sealant

how to soundproof a room from outside noise

Even small gaps or gaps can ruin your soundproofing efforts. Soundproof sealants can fill the gaps with sound-resistant elastomeric material. You should seal cracks and crevices around walls and windows.

Water-based sealants are easier to remove. If you use a solvent-based sealant, check the product label to make sure it doesn’t damage your material.

If the sealant doesn’t match the color of the wall, choose one that says you can paint it. Consider using a conventional sealant for small slots, as soundproof sealants are more difficult to operate.

Step 8: Soundproofing Of Floors And Ceilings

how to soundproof a room from outside noise

Floors and ceilings can be soundproofed using a variety of wall methods. The most common is to install one or two more layers of gypsum walls and suppress the glue between these walls. Take a simple step by covering the soundproof mattress on the floor, then cover it with carpet.

You don’t need sound insulation for the floor if there are no rooms below.

The addition of plasterboard and damping compound to concrete ceilings does not offer much benefit. Instead, you should install plasterboard and leave gaps with concrete ceilings, or fill them with fiberglass.

Step 9: Install Soundproof Panels

how to soundproof a room from outside noise

If the room is completely built but the soundproofing is not good, you can use soundproof panels. The market has the cheaper varieties, but the more expensive can be more effective.

Be sure to mount these panels to the wall with screws or other strong bonding structures.
