2. Soundproof the space between the joists

Needless to say that the space between your floor joists make a huge difference when it comes to noise passing through.

Empty space between these joists acts like a resonating box on the guitar. Preferably, you should fill this space with something. But what helps soundproof it?

Well, of course, there are mineral wool batts. It will show a great power in dealing with both airborne and impact noise.

How shouldn’t it when its density goes up to 2.5 pounds per cubic foot. With 2 inches of pure soundproofing material, you will easily block even the loudest noises.

In order to install it properly, and fill the gaps between the joists fully, you can use a knife to cut these batts to size and place it in between until there’s no space left.

The more you cover- the more effectively you will soundproof.

For those in need, the following video can help you realize how mineral wool batt works and how to install it properly. As you can see, this can be a really cheap solution to your problems.

Of course, it all depends on the size of your floor.

If we take into consideration the normal sized room of 10x10, you will need no more than $200-$300 to deal with the noise problem.

3. Use soundproofing tape

Before installing the subfloor you should probably tap the top of the joists with some soundproofing green glue tape. This is a highly affordable way to prevent the noise.

It will effectively deaden the noise produced between the subfloor and the joists while you are walking.

Yes, sometimes the main source of the noise might be just you.

Walking on the floor when there is a gap between it and the subfloor might be really annoying for your ears. 

However, here is the solution and once you finish it; you will have no such problems.

4. The subfloor is a great solution- try it!

I mean, every layer improves the insulation. With that said, there is a solution to build a subfloor. As it name says this one goes under the visible floor.

It requires to be attached firmly on the joists. For that, you should use screws or nails. There are few dominant materials used for the subfloor.

For example, you can go with plywood, OSB, and MDF panels.

They will drastically increase the insulation; they reduce both, impact and airborne noise.

If you are aiming for a cheaper solution, you should go with OSB and plywood. Plywood is the most affordable one.

Otherwise, if you are craving for the quality, and for even better-guaranteed insulation, then you should go with MDF panels.

Add some green glue, and these materials should work out great. This method of soundproofing is, frankly, the safest one and the most certain to achieve some results.

Of course, that triggers a bit bigger investment and effort needed, but all in all, it is a highly valuable solution.

5. Use green glue

You might be wondering how some glue can impact soundproofing, reduce noise, etc. Well it most definitely can.

Especially it works if you use it for the right purpose. This is the best impact noise blocker.

It will cut vibrations and bass in half. For example, if you use green glue on the subfloor, you will prevent the vibrations.

With its amusing power, the green glue will attach all the parts with enormous strength and leave no possibility of vibrations due to unsteady attachments.

Most of the vibrating noise is caused because there are some unsteady parts that dingle beneath you. Therefore, spread green glue across the subfloor.

Once done, you can use some panels to cover the area. Screw them down and secure steadiness.

After everything done, you can enjoy your attic peace, work or sleep undisturbed.

6. Put soft material on the floor

Once you have soundproofed your attic floor and done everything that you can, there is just one thing to do in order to prevent every single noise.

You need to prevent echo noise coming from yourself, and the footsteps noise. This can easily be done- two birds with one rock. Just get some soft rug like this or interlocking floor tiles.

Both are great echo deadeners and it depends only on your preferences which one will you pick.

Soft rugs are well-known, but not many know what interlocking floor tiles are. ​

These tiles are actually wood mats with great thickness, and high density, which will block not only the noise but keep the temperature a bit higher than it would regularly be.

It is extremely easy to install them, as they are like puzzles. The simplest puzzles ever seen.

Preferably, you should cover as much area as possible. The more you cover, the less echo and footstep noise will be produced.

Rug pads are kind of more popular option, but when it comes to soundproofing both are credible solutions. Nevertheless, they are great thermal isolators and will save a lot of energy.
