A bass trap absorbs low-frequency sound in the corners of a room, while an acoustic panel absorbs sound across a flat wall. Bass traps sit in corners between walls and ceilings, and panels mount flat on walls to reduce flutter echo and reverb. Below are 3 corner bass traps and 1 set of flat wall panels.
What a bass trap does
A bass trap is a sound absorbing structure made to absorb low-frequency sound, and it sits in a corner where walls meet walls and ceilings. The JBER traps mount between walls and ceilings and target low and mid frequencies, and the SD SODOCT traps absorb low-frequency standing waves in corners and ceilings. Mount bass traps from the bottom to the ceiling of the corner, or mount 3 packs in one corner of the ceiling.
What an acoustic panel does
An acoustic panel is a flat panel that mounts on a wall and absorbs sound across the wall surface. The AudioSilk panels reduce flutter echo, reverb and distortion, and they mount with removable sticky strips or spray contact adhesive. The panels measure 46 by 23 inches. Use 4 medium or large 3M Command strips per panel for the strip mounting.
Where each type goes
Bass traps go in corners, and panels go on flat walls. The JBER traps mount between walls and ceilings, the TroyStudio traps mount in corners between walls, floors and ceilings, and the AudioSilk panels mount on walls with sticky strips. The SD SODOCT traps mount from the bottom to the ceiling of a corner.
How to install them
Bass traps and panels mount with glue, tape, adhesive or pins, and the method depends on the product. The JBER traps affix with glue, double-sided tape or nails. The TroyStudio traps mount with foam spray adhesive, double-sided tape, or small screws or small T-pins, and the SD SODOCT traps mount with double-sided tape or spray adhesive. The SD SODOCT traps arrive compressed, so put them in a ventilated place for 24 to 48 hours until they expand to normal shape.

Frequently asked questions
What is the difference between a bass trap and an acoustic panel?
A bass trap sits in a corner and absorbs low-frequency sound, while an acoustic panel mounts flat on a wall and absorbs sound across the wall. Bass traps target low and mid frequencies, and panels reduce flutter echo and reverb.
Where do bass traps go in a room?
Bass traps go in corners. The JBER traps mount between walls and ceilings, the TroyStudio traps mount in corners between walls, floors and ceilings, and the SD SODOCT traps mount from the bottom to the ceiling of a corner.
Do acoustic panels need a bass trap too?
A room with low-frequency sound needs corner treatment as well as wall panels. Bass traps absorb low-frequency sound in corners, while panels absorb sound across flat walls, so each covers a different part of the room.
