Acoustic wall assemblies with dual-wall geometry and active noise-impeding properties, and / or methods of making and / or using the same

摘要

Certain exemplary embodiments relate to an acoustic wall assembly that utilizes active and / or passive sound echoes to achieve a noise canceling function, and / or methods of making and / or using it. In an active approach, sound waves within a given frequency range are detected by a sound masking circuit. In response to detection of such sound waves, an air pump (e.g., a speaker) is used to pump air into the wall assembly to actively mask the sound waves detected through echoes or the like. The wall assembly may include one, two, or more walls, and the walls may be partial or full walls. In a passive approach, sound waves are interrupted through features (e.g., holes, slits, etc.) formed on and / or within the wall itself. These techniques may be used together or separately in different exemplary embodiments.
