What Are Sound Diffusers

Sound diffusers are essential components to any studio. Their primary function is to cancel any sound from reflecting any surfaces they hit. Specifically, these panels are necessary so that you can prevent sound reflection and echoes from coloring your audio.

Moreover, sound diffusers lessen the level of reverberation in your studio. Sometimes, diffusers can reduce any ambient sound as well.

A Little Precaution

As we mentioned, studios will look and sound professionally with the help of diffusers. This is the reason why you are looking for sound diffusers, right?

However, take note that instruments like the pipe organs and piano do benefit from acoustic reverberations. In short, they work well if there are no diffusers. Therefore, you should always consider this thought before installing these diffusers. If you are usually working with the instruments mentioned above or any similar applications, then don't install these acoustic panels.

Specific Applications for Sound Diffusers

Here are the correct scenarios in where you should install sound diffusers:

  • You want to improve the surround-sound and audio clarity of your home theater.
  • You want to reduce the reverberation in large spaces such as auditoriums, churches, and halls.
  • They work well in reducing the noise of crowded areas such bars and restaurants.
  • Diffusers can enhance the quality of listening conditions to your control room and recording studio.

Moreover, you should not mistake sound diffusers for sound absorption components. We call the latter as a means for soundproofing. Therefore, they do not work similarly as diffusers.

Sound absorption materials do not really decrease the level of sound transmission in your studio. Instead, they just elevate the audio quality within a particular space by lessening echoes and decays. Moreover, they can modify the level of reflections, too.

What Tools Do You Need

The materials you need to create DIY sound diffusers are pretty standard. Furthermore, the cost of each of these materials is not that high. As a result, the level of customization that you can do is pretty unlimited.

Here are the tools and materials you need:

  • One 3/4-inch fiberglass board
  • Six 2-inch mineral wool boards
  • Speaker cloth (or any generic fabric)
  • Black gauze
  • Wood glue
  • Spray adhesive
  • Staple gun
  • Scissors
  • Hammer
  • Saw
  • Electric screwdriver
  • Picture frame hanger

 

Steps

There are different designs for sound panels. But apparently, the most common one design is the convex angle. This kind of setup allows the diffuser to bounce the sound in various directions. On the other hand, more sophisticated sound diffusers are using mathematical details. In this way, they can diffuse the sound in an efficient and schematic manner.

1

The first thing that you have to do is to place the thin MDF board above a bass trap.

2

Next, get any leftover wood and put it in the middle of the MDF board. Make sure that you will place it on the top of the bass traps.

3

You should attach the wood by the use of the staple. Specifically, the panel of wood in the middle will serve as the acme of the sound diffuser. In this way, the panel will form a convex shape when you push either of the ends of the diffuser.

4

When you are done placing the board on the bass trap, you can already nail it will the use of a staple gun.

5

Cover it with the speaker cloth that you bought so that it would look nice.

6

Once your panel is ready, you can already decide to which part of your room you will place it.

7

The placement of the sound diffuser to the wall is simple. You just need a picture frame hanger. Specifically, you have to place the hook on the back of the panel. Afterward, you can already hang the latter with the use of a nail.

Additional Tips

  • If you are using thicker materials, you might need to use tools like cordless drills. Using a staple gun won’t work on study materials. You need drills to create holes for sturdier platforms and bolts to attach them together.
  • You don’t really have to spend too much on your diffusers. You can start with cheaper materials, especially if you are just have a home studio. Meanwhile, for professionals, you might want to look for better brands for fiberglass boards. Moreover, you have to invest on the speaker cloth. Although they are expensive, they are really the best for recording and listening applications.

The diffuser will somehow act as a bass trap. Therefore, it is a bonus on your part. You can be confident that the panel will eat up the low-frequency sounds while effectively diffusing the high frequencies.

Meanwhile, the MDF material will reflect high frequencies. On the other hand, the curved design will efficiently scatter the frequencies all over your studio. As a result, you can get better recordings and audio output since there are no echoes that can pass through.

Conclusion

Sound diffusers will actually help enhance the sounding of your room. It is a necessary setup even for those who just want to start an amateur home studio in their premise. You can certainly hear the difference of your recordings once you install these diffusers.

Of course, you have the option to buy one. But if you are tight on budget and can't find a good unit that will complement your room, then you can opt for DIY sound diffusers.
