Guest Post: Charcoal Based Low Frequency Absorption

Mike Sorensen (@mikesorensen06) is a master cabinet maker, structural engineer and the author of the sound diffusion audio blog. I think you’ll find his research on activated carbon for acoustic absorption very interesting.

If you’re going to make a great recording you have to find a solution to the room acoustics. Like the black sheep of any family, room acoustics are somewhat left un-talked about given their unsexy nature. Yet they are key to helping you produce the best sound from your recordings whether in the live or listening room.
Some people think that throwing up a bit of foam here, dampening the sound there and generally shutting the door and turning off the extractor fan will do it but alas no. There is a big science that goes into it and I want to share some of my years of experience with you today so you can start to consider some of the treatments and how they work in conjunction with your studio space.

Diaphragmatic Absorbers
Diaphragmatic absorbers are powerful, low frequency, absorbing technologies. One must build a solid, sealed box that has a front wall that can “move” in reaction to sound pressure waves. This front wall movement slows the wave down, so that it can enter the inside of our sealed cabinet. Yes, the cabinet is sealed without any air holes. Low frequency waves that are 40 and 50 feet long do not care about some 1/4″ air holes in any type of absorber. With low frequencies we are dealing with waves of energy not rays.

Bass Guitar Recording

Bass doesn’t always get the attention it deserves in a recording situation. I see a lot of home recordists rush through bass recording, only to later be frustrated with the bass when it comes time for mixing. It’s really too bad because it’s the foundation of the song. A great bass will groove tight with the drums and support the guitars. Fitting it in the mix will take minimal effort and you will be loving life.

A great recording starts with a great source. When it comes to tracking bass guitar, the source is comprised of many factors:


  • Technique and playing position – Playing with a pick or with fingers or thumb. Intensity, Playing close to the bridge, in the middle or close to the neck. Choose what is appropriate for the song
  • What is played – playing bass lines that serve the song and don’t clash with the drums or guitars rhythmically or melodically.
  • Tuning – Check the tuning often


  • Strings – new strings usually sound best and give you the brightest tone to start with.
  • Electronics (Pickups and EQ) – The pickup selection and tone settings
  • Wood and construction – The wood used in the neck and body really effect the sound. Maple and Ash are bright and punchy, mahogany is thicker and darker.

In Flames in the studio 2011

In Flames is a great metal band from Sweden. On their YouTube channel they’ve posted 6 short documentaries on the progress of their 6th studio album. There’s not a lot of techniques to see but there is some discussion of the production and lots of nice gear to see and hear.
