The joined acoustic wall panels define a doorless aperture in the modular acoustic structure, an internal chamber, and a straight acoustic hallway connecting the doorless aperture and the internal chamber via an internal aperture. The straight acoustic hallway absorbs soundwaves travelling between the doorless aperture and the interior chamber. The acoustic wall and/or ceiling panels may include an acoustic absorptive surface and an acoustic reflective surface. The acoustic properties of the interior chamber and/or the straight acoustic hallway may be altered or tuned by changing which of the surfaces faces an interior of the modular acoustic structure. The size of the interior chamber and/or the modular acoustic structure may be adjustable by adding and/or removing acoustic wall and/or ceiling panels. ## Claims ### Claim 1 A modular acoustic structure, comprising: acoustic panels joined together; an interior chamber defined by the acoustic panels; a doorless aperture defined by the acoustic panels; a straight acoustic hallway defined by the acoustic panels that: has a length of at least two of the acoustic panels; connects the doorless aperture and an interior aperture between the straight acoustic hallway and the interior chamber such that the doorless aperture and the interior aperture are non-aligned; and absorbs soundwaves travelling between the doorless aperture and the interior chamber. ### Claim 2 (depends on 1) The modular acoustic structure of claim 1, further comprising a window coupled to one of the acoustic panels. ### Claim 3 (depends on 1) The modular acoustic structure of claim 1, wherein the acoustic panels define the interior aperture between the straight acoustic hallway and the interior chamber. ### Claim 4 (depends on 3) The modular acoustic structure of claim 3, wherein the interior aperture is perpendicular to the straight acoustic hallway. ### Claim 5 (depends on 1) The modular acoustic structure of claim 1, wherein the acoustic panels defining the straight acoustic hallway include an acoustic absorptive interior surface and an acoustic reflective exterior surface. ### Claim 6 (depends on 1) The modular acoustic structure of claim 1, wherein at least one of the acoustic panels is positioned between the straight acoustic hallway and the interior chamber. ### Claim 7 (depends on 1) The modular acoustic structure of claim 1, wherein the acoustic panels each comprise a layer of wood, a layer of polyurethane foam, and a layer of fabric. ### Claim 8 A modular acoustic structure, comprising: acoustic wall sections joined together; acoustic ceiling tiles placed on the acoustic wall sections to form a ceiling, at least one of the acoustic wall sections or the acoustic ceiling tiles include an acoustic absorptive surface and an acoustic reflective surface; an interior chamber defined by the acoustic wall sections; an aperture defined by the acoustic wall sections; an acoustic tunnel at least two of the acoustic wall sections in length defined by the acoustic wall sections that absorbs soundwaves travelling between the aperture and the interior chamber; and an interior aperture defined between the interior chamber and the acoustic tunnel that is non-aligned with the aperture; wherein: changing which of the acoustic absorptive surface and the acoustic reflective surface faces an interior of the interior chamber alters acoustic properties of the interior chamber. ### Claim 9 (depends on 8) The modular acoustic structure of claim 8, wherein the acoustic reflective surface comprises wood. ### Claim 10 (depends on 8) The modular acoustic structure of claim 8, wherein the acoustic absorptive surface comprises polyurethane. ### Claim 11 (depends on 10) The modular acoustic structure of claim 10, further comprising fabric positioned on the polyurethane. ### Claim 12 (depends on 8) The modular acoustic structure of claim 8, wherein changing the acoustic reflective surface to face the interior of the interior chamber increases reflection of soundwaves within the interior chamber. ### Claim 13 (depends on 8) The modular acoustic structure of claim 8, wherein changing the acoustic absorptive surface to face the interior of the interior chamber decreases reflection of soundwaves within the interior chamber. ### Claim 14 (depends on 8) The modular acoustic structure of claim 8, wherein the acoustic ceiling tiles are unfixed from the acoustic wall sections. ### Claim 15 A modular acoustic structure, comprising: acoustic structural modules removably joined together; an interior chamber defined by the acoustic structural modules; an aperture defined by the acoustic structural modules; an interior aperture defined between the aperture and the interior chamber that is non-aligned with the aperture; and an acoustic passageway at least two of the acoustic structural modules in length defined by the acoustic structural modules that connects the aperture and the interior aperture and absorbs soundwaves travelling between the aperture and the interior chamber; wherein a size of the interior chamber is adjustable by: joining an additional acoustic structural module to the acoustic structural modules; or removing one of the acoustic structural modules. ### Claim 16 (depends on 15) The modular acoustic structure of claim 15, wherein the acoustic structural modules define a gap underneath the modular acoustic structure. ### Claim 17 (depends on 15) The modular acoustic structure of claim 15, wherein the additional acoustic structural module is joined to the acoustic structural modules by: separating two modules of the acoustic structural modules that are joined; and joining the additional acoustic structural module to the two modules. ### Claim 18 (depends on 15) The modular acoustic structure of claim 15, wherein removing the one of the acoustic structural modules comprises: separating the one of the acoustic structural modules from two modules that adjoin the one of the acoustic structural modules; and joining the two modules to each other. ### Claim 19 (depends on 15) The modular acoustic structure of claim 15, further comprising joining structures positioned between the acoustic structural modules. ### Claim 20 (depends on 15) The modular acoustic structure of claim 15, wherein the aperture ventilates the interior chamber.
