Too often home studio owners try to correct the acoustics of their own shooting room or control room by spending money unnecessarily and worsening the room acoustics. I often see being completely full of pyramidal sound-absorbing, among other things of thin size of 2 or 3 cm, this is really a horror, this type of panels absorbs only the high frequencies which, among other things, must remain in part for make the room sound alive. We often forget the most important part which are the low frequencies that must be eliminated through the bass traps that have various shapes, the most common are triangular and must be placed in the corners of the room. There are mainly 2 types of bass traps, i bass trap a broadband connection ei membrane bass trap resonant in addition to helmholtz resonators which have a very similar concept of absorption.

Broadband bass traps

Acoustic Foam Broadband Basstrap: Broadband bass traps are the classic sound absorbing panels that you can usually see in the corners (in various shapes), they are triangular and made entirely of acoustic foam or polyurethane foam. If you don’t have precise angles you can opt for cylinder-shaped bass traps, also called tube traps or pipe traps. This type of bass trap does its job and costs little, below you can find a bass trap model that costs about 16 euros with a size of 30x30x80 cm. The shape is not important, the thickness is important, so the thicker the panel, the more you will be able to absorb the lower frequencies, also the type of material used can increase the absorption power.

The broadband bass traps in rock wool or glass wool: If you want to increase the level of sound absorption you can opt for bass traps made of mineral wool, the most common bass traps are made of rock wool or glass wool. Unfortunately these bass traps cost much more than their acoustic foam counterparts but are suitable for those who want to do a more professional acoustic correction for various reasons. First of all, the mineral wool bass traps are usually covered in acoustic fabrics such as cotton and polyester that allow not to have an aggressive absorption with high frequencies, remember that when you put too many panels in a room, you risk making the room become dead, so start saving some high frequencies so that you don’t have to remove some panels later to regain some liveliness in the room.

One solution could be to use bass traps coupled to wood, there are many companies that create this type of panels, if you want to empty your wallet you can turn to Gikacoustics which offers the Alpha CT angular bass trap.

Where to buy professional glass wool bass traps?

Pik broadband basstraps ( see price or buy ) have an excellent value for money, are covered in high quality acoustic fabric and have a wooden frame filled with high density glass wool at a cost of 49 euros per 104x53x10 cm panel. These panels if placed in the corners are able to increase the absorption of low frequencies. If you want to absorb the bass in a more massive way, we recommend purchasing the tubetrap panels that you find below.

Here are other more expensive but not better mineral wool bass traps:

Bass traps are not only angular ones, there are also flat ones that can be placed directly on the walls, preferably near the corners, but the advice is to act directly on the corners. While it is very easy to do damage on the mid-high frequencies, it is much more difficult to do damage when working on the absorption of low frequencies, you can also exaggerate, the absorption will hardly be excessive, also this will allow you to reduce even the frequencies above the point that a few more panels will be needed to absorb the last remaining annoying frequencies, so it is advisable to intervene on all possible angles, they are not the vertical ones, even on the horizontal ones between the wall and the ceiling.

If you have difficulty inserting the corner panels due to obstacles or other reasons (for example you have a radiator that prevents you from putting the panels), you can opt for a cylindrical bass trap that you can build with little money by following these instructions in English while if you want to get nice cheap and high quality tubetrap without trying to build it we recommend the Pik tube trap at a cost of 99 euros against the 150 euros of the Hofa tubetrap.

With the broadband bass traps, the first reflections, the standing waves and the echo effect are reduced, in fact their only limit is the fact that they absorb all the frequencies, so in case your room already sounds dead of freq . high, you have to opt for membrane bass traps that are more selective absorbing only the low frequencies leaving almost unchanged the mid – high frequencies. We recommend that you use free acoustic analysis software such as the REW Room EQ Wizard coupled with a measurement microphone such as the behringer ecm8000 .

Resonant membrane bass trap

Membrane bass traps, if purchased, cost a lot, but they can be built very easily but be careful because they must be tuned to the frequency you intend to absorb. If you are not an expert we recommend using broadband bass traps as it is very easy to do damage by absorbing frequencies selectively. We recommend using these panels only if after using too many absorbent panels you realize that it is necessary to remove some broadband panel to get more high frequencies in the room, in reality this need arises especially when only acoustic foam absorbers are used but if designed well your acoustic piano from the start, you can save yourself from using these panels. In order not to exaggerate with the absorption of frequencies, acoustic speakers usually made of wood are also used, which instead of absorbing break the sound waves and spread them in the room in a balanced way. Surely you are wondering, where to buy membrane bass traps? I think it is useless to give you the link due to the high prices, but if you want to get hurt you can buy them on the website of gikacoustics , there are also other manufacturers that sell the various types of bass traps, for example auralex, vicoustics, realtraps, primacoustic, etc. but unfortunately if you want to save you have to build them.

How to build bass traps?

If you want to build membrane bass traps you can click on this guide, if you want to build tube traps you can click on this guide and finally, if you want to build simple but more suitable broadband bass traps, we recommend watching this video.

Where to buy the materials to build bass traps?

To create the bass trap frame you can go to any DIY in your city, there are also online sites that allow you to get tailor-made wooden slats. If you are looking for rock or glass wool and acoustic canvas by the meter to cover the bass traps, take a look on amazon:
