GIK 244 Bass Traps vs Foam bass traps with REW measurements!

We put two products to the test: our GIK 244 Bass Traps against large Foam Bass Traps.

Foam is a cheap porous material that’s lightweight and easy to work with. Both Polyurethane
and Basotect foams are made into acoustic treatments. Plenty of people have attempted to use packing foam as acoustic treatment and some companies make full sized corner pieces and market them as bass traps.

The truth about foam as an acoustic absorber is that you get what you pay for. Foam can be useful in absorbing mid and high frequencies but falls short in absorbing the low frequency sound that plagues so many studios and music rooms.

What about those large foam corner traps I mentioned earlier? Even those larger pieces of foam aren’t effective at treating bass frequencies the way a proper Bass Trap does.

This has to do with two reasons: “gas flow resistivity” or the airflow resistance within a unit of thickness & and purely size. Foam is hard to find in larger sizes where mineral wool can be used in larger treatments.

The structure of the fibers within a block of foam don’t allow air to pass through as easily, compared to the fibers in something like mineral wool or fiber glass.

Because the fibers of foam don’t let the sound waves penetrate throughout the entire mass of the block as easily, so foam isn’t going to be as effective.

We’ve actually run a test comparing 8 244 bass traps to the similar area of acoustic foam.

Keep in mind, this test is a product to product comparison, not material to material. In this test we used a 24in GIK panel vs a 17in foam block as foam is not available in directly comparable sizes.

The results are compared to a measurement taken of the room without any treatment. With the foam, we only see small changes in the frequency response and hardly any improvement in the sub 100Hz range. With the 244 traps we can see drastic changes around 65 and 100 Hz. Looking at the waterfall graphs, there’s a huge improvement in the decay time at 65Hz when compared to the foam.

Using our patented flex range products we can tailor how much high frequency or low frequency absorption goes into each panel on the 244 monster and soffit bass traps. This let’s you hone in on the frequencies that are causing issues, by customizing your panel's performance."
