Acoustic wall assembly having double-wall configuration and passive noise-disruptive properties, and/or method of making and/or using the same

An acoustic wall assembly, comprising:

• inner and outer walls that are substantially parallel to one another, a gap being defined therebetween;
• and
• at least one set of reverberation-generating elements sized, shaped, and arranged in the inner and/or outer walls to selectively generate pressure waves in the gap to disrupt, via a reverberative effect, noise in a predetermined frequency range that otherwise would pass through the acoustic wall assembly.

A method of making a sound-masking wall assembly, the method comprising:

• having inner and outer walls that are substantially parallel to one another, a gap being defined therebetween;
• and
• forming, in the inner and/or outer walls, at least one set of reverberation-generating elements that is sized, shaped, and arranged in the inner and/or outer walls to selectively generate pressure waves in the gap to disrupt, via a reverberative effect, noise in a predetermined frequency range that otherwise would pass through the acoustic wall assembly.
