Acoustimac separates fact from myth about Egg Cartons.

Jan. 24, 2011 - PRLog -- He said that someone told him they would absorb the noise from the sound and help the room sound better. It looked unusual, but we all thought it was working fine.  
One day, our drummer got tired of looking at them and decided to tear them down.  We played there a few days later and noticed that the egg cartons weren’t really helping all that much. I mean they did something, that much we knew.. but not nearly as much as we thought.

When it came time to cut our first demo at a recording studio we noticed something about the studio walls; they were covered in strange asymmetrical shapes.  We asked the sound engineer who worked there if those were for absorbing noise (like we thought the egg cartons were). He told us that they were sound diffusers used to make the sound in the room more airy and wide and that they provided no absorption at all.  

The engineer pointed at the walls and corners and showed us some large boxy shapes that he said were absorbers and bass traps (The whole time we thought they were speakers) and are what really make the big difference.  He also said he paid a fortune for them.

When I got back home that day I started digging around on the web and realized an important distinction, there is a big difference between sound diffusion and absorption.
To diffuse a sound wave is to break it apart and send its arcs in different directions thereby making the sound wide and airy.

You see, reverb and slap-back comes from sound waves bouncing off of flat surfaces. With diffusers, your walls are no longer flat and the waves don’t really bounce but deflect and veer off into many directions because of the uneven and angled surfaces found on diffusers. That’s when I realized that the egg cartons at our drummer’s studio were acting as diffusers, well sort of.

Absorption is more important than diffusion. That’s where acoustimac comes to the rescue! Using Mineral wool, fiberglass or Acoustimac’s new eco friendly Ecoustimac insulation, you are essentially soaking up the sound waves on both high and low frequencies. This eliminates the wall reflection which in turn reduces the reverb in the room, making the sound more natural and tight.

So should I use diffusers or absorbers?

The answer is both if you can afford it. If you can’t then sound absorption is more crucial than sound diffusion. You can achieve some diffusion at no cost by placing bookshelves, and smaller pieces of furniture in the room. All of these pieces have hard, sharp corners and all will help diffuse the sound.

For sound absorption, acoustimac offers an array of inexpensive acoustic panels and bass traps. All 100% hand crafted right here in the USA.  Shop a la carte or save money with Acoustimac’s pre-designed room packages.
