Although any form of noise can be annoying, low sound waves are among the worst. a quick answer:
When it comes to blocking low sound waves, the best option is a combination of mass and weakening materials. Low materials need more materials to block the highest frequencies, but the use of many sound tests solves the problem.
In this article, I will analyze specific information about why low frequencies are another problem that must be solved together with the most effective solutions.
What are low sound waves?
Low frequency sound waves generally cover the range of 100-150 Hz and are, for example, the type of waves that come from a stereo subwoofer. However, many noise sources generate serious frequencies.
Sound wavesThey are caused by vibrations, either by air or through solid materials. For sound waves, it needs a remedy to travel, so there is no noise in a vacuum.
HertzIt is a frequency unit and the noise has a wave standard that corresponds to different frequencies.TomásIt is the measurement unit that refers to how the human ear listens to a sound wave.
Higher sound waves work at a higher frequency, while serious frequencies correspond to the lowest slope noise.
Sound waves consume energy when they travel and this energy is gradually lost because sound waves allow air particles to vibrate. Therefore, sound waves cannot travel indefinitely.
Low sound waves can increase more than high frequency waves because they do not consume so much energy. They transfers less energy to the environment with which it travels, which means that it can achieve longer distances than the high wave frequency.
This applies to traveling through air and solid materials. High frequency sound waves are more easily blocked by heavy materials because they lose their energy faster.
Low frequency waves, however,Cause less vibrations in the materialAnd so it can happen more easily. Therefore, they need heavier and thick solid materials to block them effectively.
Although this logic helps when noise such as fog horns have to cover huge distances, it is not very useful when it comes to sounding evidence against unwanted low noises at home.
There are many low frequency sources, which include:
- Road traffic (cars, buses, trains, etc.)
- Appliances (washing machines, dryers, boilers, etc.)
- He lied
- construction sites
- Appliances and credits, etc.
Fortunately, it is possible to combat many of them with soundproof solutions. However, the effectiveness of their options depends on the proximity of the source and its volume.
Verify the noise source
The first thing to do before experiencing soundproofed solutions is to find the noise source in the best possible way.
Although you cannot define exactly if you leave your home, it should not be too difficult.
- You are leaving your home listen to the walls and windows to see if the noise is driving.They can even vibrate a little.
- Otherwise, see your home in search of devices used. It can be a washing machine or dryer or a teapot.
- It is easier to check them by turning them off and seeing if the sound stops.
- Otherwise, the source can be a bit more difficult to verify, Comob.Tubes.
- Is it a neighbor? Is the noise source on one side of your house?
The more effectively the noise source can limit, the better the sound insulation solutions will be.
It is important that such evidence against bass can be expensive, so you probably want to be as efficient as possible.
Find the noise source in something like a boiler or a certain device reduces the necessary work.
This is how it blocks low or low noise axes
Here are some options on how to block low or low frequency sound waves:
1. Add the dry wall as a sound barrier
The bass can vibrate even more through solid structures. Therefore, adding more mass reduces its ability to create it. Although the dry wall is not the heaviest material, it is immediately available and cheap.
If the noise source is on a single wall of your house, add one or two layers of additional wall to increase the mass and the thickness of the surface.Green tail(Amazon link)Teach the layers an additional sound of the sound.
You can buy an soundproofed drying wall for this exact final. It continues an additional layer damping material and more mass. In this way, it can reduce the amount of material that must be maintained on the wall.
2. Peel the wall
A more effective option as long as you have time and skills is forBy the wallApply basically means isolating both sides of the other wall, which means that sound waves are avoided.
You can use staggered nails or double nails, which contain a high density insulation layer in the middle. Duplicate prisoners require more work and basically interpret the entire wall.
However, when it comes to low frequencies, this is probably the best option because they can be worried about controlling the waves. You can find a simple tutorial videoWhat dissociatesFor more information.
If you have no resources to dissociate a wallresistant channelsInstead, they isolate the gypsum panel of the nails and basically offer the same results for less money.
Combine channels resistant with adequate cavity wall isolation and must have a very effective solution for block frequencies.
3. Isolate each wall cavity
The wall cavities are the enemy of a sound noise. The empty space can contain sound waves and is perfect for reverberation, which can increase sound waves. Therefore, the low point of the sound system of itsNeighbor seems to be so high what it is.
Fill the cavity with a bit firmlyInsulation made of glass woolIt is an excellent way to solve this problem. Fibers are packed in a random pattern in a thick and thick material, which is perfect for this work.
The density of the material has an effective effect on the sound waves and prevents them from walking through the wall. The empty space also fills, which reduces echo and reverberation.
Although this option alone may not completely block serious frequencies, it combines them with some resistant channels, or dissociation does a good job.
4. Use an isolation box for small devices
If the low frequency source is a small device, P.B.a computer or even a boiler, aIsolation boxI could solve the problem.
Although they have been absorbed at home to receive acoustic treatment, they are something good for this. Confirmation was projected with solid isolation, and we need it.
An isolation box must deliver approximately 30 dB of noise reduction and contribute with serious frequencies of the pillow.
However, its size means that it is not a practical solution for larger or higher devices. This is an affordable solution for small problems, such as: b.High devices fans.
5. Create a DIY window plug
Although the sound of sound is probably not all its noise problems, this can make a big difference.
The windows are one of the weakest areas of the house when it comes to noise infiltration. This is mainly due to the fact that they are thinner than the walls and, therefore, facilitate noise.
A simple solution for this is to create its own soundproof window plug. For this you need:
- Some saw wood
- Vinyl
- Acustic foam
- Green tail
- Some
- Measure the size of the window, including height, width and depth. MANTING Centimeters or two clarifications between the plug and the window.
- However, it must also be approximately 1 inch on the sides to create a tight seal to create the structure of the window. Consider this in its measures when creating the table.
- Measure the MDF parts of the same size as the back and sides. This is the basis of its frame.
- Cort a piece of MLV as large as the table.
- Paste the green glue or other connection material.
- Cort a piece of acoustic foam of the same size and paste a space around the edge to repair the sideboards.
- Set the sideboards and the clove out of security. It must fit into the depth of the window structure and leave a small amount of approval.
- Ensure some handles on the back and the end.
This is a very effective solution to block the bass frequencies that come from Windows because it gives this weak area a dough and a shock absorber sounds.
In addition, the small gap between the plug and the window creates dead air, which contains the sound waves and prevents it from hugging it.
However, the main disadvantage is that it fully blocks the light. For this reason, I probably only want to use it at night, but at least sleep better.
6. Use nursing curtains
Curtains Para Juzgar DomIt should not be your main choice if you block serious frequencies, but it will definitely help.My recommended sound insulation curtains.
Real mainly in weak areas such as doors and windows, but can also hang them in front of the walls if necessary.
They differ from normal curtains because they have an additional layer damping material, which makes them thicker.
It is true that they are better to block the most frequent sound waves, but they will also make a difference in bass. You will not more with quieter serious sources.
Go as thicker as possible to achieve the best results, but do not expect miracles. I say you are a very economical solution that is not particularly invasive.
7. Be sure to seal all the holes in the house
You should never ignore how important it is to adequately seal all the holes and cracks in your home. Although you do not ask alone, this will still make a difference.
Sound waves act as heat: they can enter the smaller rooms and escape.
In addition, a crack between a wall and a window creates the most vibration potential, which can increase frequency waves.
Its 2 best friends for this work are the elimination of the weather and the acoustic seal. The weather street is designed to be sealing small holes around doors and windows to improve thermal insulation. However, it also works well to soundproof.
The acoustic boiler is a great material that converts sound vibrations into thermal energy. The opposite of the normal cunning is much more elastic, which means that the building changes over time.
Combine this option with several other sound creation solutions and must have a very effective barrier against serious frequencies, regardless of where it comes from.
8. Install some serious traps
BassThese are specially developed foam pieces that work against low frequencies. His structure and composition differ slightly from normal acoustic foam and generally sit in the corner of a room.
However, remember that it has been designed in such a way that it prevents the low escape from a room instead of entering it. They imply the lower waves to reduce the echo and reverberation so that it is not the solution it is looking for.
However, it will be useful if, for example, someone at home plays high music (or television) and wants to work in a nearby room.
Buy a 4 package and put it in the corners of the room. If this combines this with some heavy curtains, it has a solution that effectively blocks the bass from an adjacent room.
Some last thoughts
When it comes to blocking low sound waves, their best options are dissociating and adding much more dough.
As already mentioned, this is because the bass can travel even more through fixed surfaces that really avoid the dough.
Fortunately, when trying one or more of the previous solutions, a house must effectively end to sound against low frequencies.
