If you invest in only one acoustic treatment for your in-home studio or home theater, make it bass traps. Corner bass traps are very effective at flattening a room’s low-frequency response and absorbing a range of frequencies, including low and mid-frequency sounds.

Corner foam bass traps are especially useful in home studios, home theaters, and smaller rooms where low and mid-range frequency problems are most common. They may also be used in commercial applications with the right product selection.

The Many Benefits of Bass Traps

There are many benefits to installing bass traps. In fact, if you asked studio professionals, many would recommend bass traps over acoustic foam as the first thing to buy when upgrading your home studio or music room. They are that good at acoustically treating a room.

  • Greater clarity of sound from speakers.
  • Reduced or eliminated echoes and reverberations.
  • Absorption of unwanted mid- to low-frequency sounds.
  • Proper diffusion of sound throughout a room.
  • Dramatically improved sound recording quality.

Bass Traps vs. Acoustic Panels?

If you’ve been doing some reading on the subject, you may have seen the terms acoustic panels and bass traps. Both are panels made of sound-absorbing materials that are either porous or resonant. However, they serve slightly different purposes when it comes to improving acoustics

Acoustic foam panels in 1.5” and 2” thicknesses are effective absorbers of mid- to high-frequency noises. Bass traps have 4” panels – twice the thickness of acoustic panels – and can also absorb low frequencies and bass tones. Both types of panels absorb high frequencies, but bass traps are the better option for treating low-frequency noise.

Usually, bass traps are installed in corners, whereas acoustic panels are usually only installed on flat walls. The benefit of corner bass traps is the sound dampening at the meeting point of two or three points of contact. Low-frequency sounds tend to reverberate in corners, and bass traps solve this problem.

Types of Bass Traps

There are two types of bass traps to choose from, defined by the materials they’re made of and how they dampen sound. We are focusing on porous absorber bass traps in this article, but it can be helpful understanding all the options.

Porous Absorber Bass Traps

These wedges of acoustic foam are simple, effective, cheap, and easy to use. They’re also the most common variety sold for home use.

A porous absorber or foam bass trap generally consists of absorbent, sound-dampening material, a frame, and some sort of covering. Materials often used in porous absorber bass traps include:

  • Fibrous or foam-cell core
  • Wall-mounted frame made of metal or wood
  • Porous fabric cover

Resonant Absorber Bass Traps

This type of bass trap is more complicated, often more expensive, and more challenging to use in comparison. It requires more knowledge of acoustics to design and install in a room.

Resonating bass traps absorb sound at their frequency of resonance. Designing and building resonant bass traps requires a greater understanding of resonance, typically acquired by measuring the room or calculating its modes. A room’s mode refers to the tones of sound that tend to build up inside.

There are two types of resonant bass traps: Helmholtz resonators and panel absorbers. Helmholtz resonators are somewhat old-fashioned, so panel absorbers are more common now.

There are differences in the absorption spectrum between resonant and porous traps. Resonant bass traps have a have narrower spectrum, while porous bass traps have a broader absorption spectrum.

Resonating absorbers are highly effective but require a great deal more time to design and build. You’ll need to know exactly which frequencies you need to block.

8 Best Bass Traps for Home Studios

Read on as we review the best bass traps for home studios, office, and home theatre. You’ll see that each one has dimensions and a noise reduction coefficient (NRC) rating to help you gauge how efficient it is at absorbing sound.

1. Auralex Acoustics LENRD Bass Trap

3. Audimute Acoustic Bass Trap

Audimute Bass Traps

Audimute Acoustic Bass Traps are 4” thick to maximize low-frequency sound absorption. Audimute uses a core of recycled cotton and cellulose fibers, making it the greenest bass trap on the market. They have an NRC of 1.15 and come in various fabric options.

The Audimute acoustic bass trap material is naturally thicker than egg crate-style foam top layers and offers maximum absorption without using fiberglass filling, such as that used in other foam options.

Unlike acoustic tube traps, Audimute’s acoustic bass traps hang on the wall for fuller room coverage. Corner bass trap orders include a Z-clip for mounting, but corner wall mounts must be purchased separately.

Among the eight choices listed here, Audimute Acoustic Bass Traps are among the more aesthetically pleasing. These bass traps come in three sizes: 24” x 24” x 4”, 24” x 36” x 4”, and 24” x 48” x 4”.

Bass Trap FAQs

Still have questions about bass traps? Here are some answers to the most common queries.

How Many Bass Traps Do I Need?

The answer depends on room size, application, and budget. In a small- to medium-sized room, the minimum number of bass traps required is between two and four, ideally with one in each corner.

Bass tends to build up in the trihedral corners of a room where three points meet (wall-wall-ceiling and wall-wall-floor), so this is clearly where the bass traps will be most effective. If floor-to-ceiling units are in your budget, these will provide the most complete coverage

If budget is not an issue, placing bass traps on dihedral corners – at the midpoint of each wall at the wall-floor and wall-ceiling touchpoints – is the next step. Additional bass traps further reduce low-frequency, unwanted sound reflection. You’ll need six to eight bass more traps to cover the dihedral corners.

That brings the total to eight to twelve bass traps.

Where Should Bass Traps Be Placed?

As stated above, place bass traps at the trihedral and dihedral corners of a room. As a reminder, trihedral corners are where three surfaces meet, and dihedral corners are where two surfaces meet.

At a minimum, place two bass traps in the corners located nearest the primary sound source, floor to ceiling. Sound sources may include:

  • Amplifiers or speakers
  • Locations of acoustic instruments or vocalists
  • Home theater soundbars

If you want additional low to mid-frequency sound dampening, additional bass traps may be mounted floor to ceiling in all four corners, as well as on the dihedral midpoints of walls touching either floors or ceilings.

How Thick Should My Bass Traps Be?

Most common, in-home bass traps consist of porous absorbing acoustic foam and rely on passive absorption and friction to dampen unwanted sound. This means bass traps – especially those made of porous absorbing materials like foam or fiber core – need to be a minimum of 4” thick. Ideally, your bass traps will be as thick as 8”.

Active absorption requires using resonant-absorbing, limp membrane bass traps which require expertise in acoustics to design and install. The thickness is not as important as the frequency they’re designed to absorb.

Can’t I Just Use Acoustic Panels?

Acoustic panels absorb and control mid to high-frequency ranges and are generally thinner than bass traps. Bass traps are often two to four times thicker than acoustic panels.

Bass traps treat low-frequency noise, generally installed in corners, floor to ceiling. Acoustic panels are typically flat wall panels, whereas bass traps are more often triangular and designed to fit in trihedral and dihedral corners. However, there are flat panel, corner-mounted bass traps as well.

There are advantages to using either kind of bass trap. Triangular bass traps have more mass for sound absorption, while flat-panel bass traps use an air gap between panel and wall that covers more surface area with less material.

In either case, bass traps are used to augment acoustic panels and to absorb the mid-to-low frequency sounds. Thinner, less dense acoustic panels dampen mid-to-high frequency sounds the best. Using acoustic panels alone is not a viable solution for managing mid-to-low frequency sounds.

When purchasing, or building bass traps, consider thickness, height, and value for money. Take a closer look at any the products on this list, and you’re sure to find one that fits your needs.
