For the sound outside, you will need to identify the source of the sound in the room. It could be through a particular wall, door, ceiling or window.

Put the blanket over the source of the sound. That way, before the sound gets in the room, the blanket will help in absorbing its energy.

To keep sound inside the room, you will need to put the blankets on all sides of the room.  Most of the sound energy will be absorbed by the blankets before it reaches outside the room.

These panels are generally pretty lightweight and come in a variety of colors to match your decor. Inexpensive acoustic panels, like these foam panels, are easy to install and help to absorb unwanted sounds.

Use a panel that is mostly fiberglass with a thin Mylar perforated facing. These types of panels have the highest ratings in sound absorption values.

Some of the panels already have an adhesive peel. But in a case it is not having, you can use panel mounting tape or spray adhesive to glue the panels to the walls or ceiling.

You can cover all or just parts of the surface, depending on the amount of dampening you desire. This cuts down on the ‘noise’ inside the room.

4. Soundproof Curtains or Drapes

Soundproof curtains can be found in many numbers these days. All promising the same thing. But not all are effective.

A good soundproof curtain is quite heavy and well insulated. This, however, makes them expensive. But not to worry. You can still find decent and cheap soundproof curtains to use for your room.

One way to deal with those small gaps and cracks is to use a soundproof weatherstripping tape. This product is quite cheap and different brands have their prices. But with just about $10, you can get one online or at your local builder’s store.

For a more permanent solution to sealing the gaps, you can also use caulking. Caulking takes a little bit of time but it is also a cheap, efficient and permanent solution. Unlike the weatherstripping tape that you can easily peel off.

These caulks also can be found at different prices and for a little amount, you can get one that will do a decent job.

When it comes to taking care of the door jamb, you can use the weatherstripping tape or get a door jamb kit to seal the top and the two sides of the door.

6. Install a  Door Sweep or Draft Stopper

A door sweep or door draft stopper will take care of the gap between the door and the floor. This way and sound that is escaping or leaking through there will be blocked.

Both perform a similar function of helping you block noise. The door sweep might take time to install while the door draft stopper doesn’t take long to fix.

There are other benefits that come with either of these. They will in preventing insects, bugs, cold air or warm air from entering the room.

7. Fill the Room with Furniture or Other Items

Strategically placing your furniture in problem areas can break up sound waves and cause the sound energy to dissipate far more quickly than it would if you just allowed it to bounce freely around your room.

If you have a problem with sound coming vibrating through a wall then you could place upholstered furniture against the wall to help absorb the vibrations, this can work very well as the sofa or armchair acts as a dampener preventing your wall from amplifying the sound vibration as a drumskin does.

For example cabinets or shoe racks could be placed near the door to break up sound that travels through the gaps in your doorframe.

8. Place Thick Rugs on Floor

Not only do these floor rugs give the room a good visual appeal, but they also help in absorbing echoes and sounds. If the room floor is made of laminate, wood, tiles or even marbles floor, you will notice that these types of floors transmit impact sound easily.

An example is footsteps on heels, an object falling on the floor, hammering, jumping, etc. Immediately they have an impact on the floor, the vibrational sound is going to travel fast through the floor to both upstairs and downstairs.

To minimize this impact sound, installing a carpet or a rug on the floor will help to dampen the impact of the sound vibrations.

9. Puzzle Exercise Mat

Using anti-vibrational pads, you can mount shaky items like the speakers, the washing machine, the dishwasher or any other item that makes sound due to their contact with the floor.

Some of the household items can make some uncomfortable buzz that you are not even aware of. You become aware of it only once it is gone.

Putting these vibrational items on a carpet or rug its good. They will only spoil the beauty of the carpet or rug. There are anti-vibrational pads specifically made for mounting these kinds of items.

They are soundproof and anti-wear and tire. Simple get one and place it underneath the item to make the buzz quieter.

These anti-vibration pads can be found for about $12 per pack of 4. It is enough for one machine, and it really serves its function.

After you have placed them underneath the machine, you will be able to hear the difference.

The subtle buzz of a working machine will be even more muffled now that it has something soft underneath it to absorb the sound.

Your neighbors have the right to enjoy their space as well without been intimidated. Therefore, if the upstairs neighbors are disturbing your peace downstairs, You can soundproof your ceiling by placing noise-absorbing materials such as mass loaded vinyl mat, ceiling tiles, ceiling foam panels, etc.

These soundproof materials will help reduce the impact of the noise from the upstairs but not completely eliminate it.

Alternative Cheap Soundproofing Ideas Using Construction

If the room walls are made of thin drywall, you can consider adding extra mass by construction. extra mass can be added to the existing drywall.

If you are improving the existing wall, you can build a basic wall frame and attach it to the surface, anchor it with studs, then cover it with a new layer of drywall or sheetrock. When choosing the drywall, ensure it is thick and denser to be more soundproof.

Decouple the wall

You do this by separating the two layers of the wall.  Build a wall from two sheets of drywall or sheetrock with as much space as possible between them.  When sound travels into the wall, some f the energy will be absorbed and some reflected.

So the first wall will absorb and reflect the sound before it gets to the second wall.  Decoupling can make worse blocking out low frequencies, due to resonance of the wall, if the gap is only 1 inch or less, use a damping compound like green glue to fill it to counter this effect.

Use sound Clips or Resilient Channels

These soundproof materials are placed somewhere between the studs and the drywall, therefore, providing another layer of sound reduction.

Resilient channel is a springy metal channel designed for soundproofing. Screw this to the studs and drywall using offset screws. This may improve high-frequency blocking at the expense of low frequencies.

Sound clips are the most effective method, absorbing sound with heavy rubber components. Screw them into the studs, insert a hat channel, then screw the drywall into the channel.
