Acoustical Bass Traps for Low Frequency Control

Low frequencies are particularly difficult to absorb due to their long wavelengths. Bass traps are designed and constructed to absorb these longer waves and control unwanted room resonances.  Thicker absorbers offer broadband absorption extending to lower frequencies.  These are available in many shapes, sizes and material compositions. Other materials use flexible membranes to attack low frequency resonance.  The term “bass trap” can be considered counterintuitive since some devices eliminate low frequency room cancellations, allowing the bass to be heard.
