Definitions

  • This invention relates to acoustic architecture design for recording rooms and more precisely, architectural design for prefabricated acoustic studios where techniques of mechanical and non-mechanical devices are applied for acoustic manipulation in music recording.
  • Hexahedron 6-faced polyhedron, synonymous: cube. Volumetric 6-faced figure, 1 superior, 1 inferior and 4 lateral faces.
  • Corners (1) of a hexahedral room are the 8 edges that are formed with the near encounter between their 3 walls at 90°; walls that conform their architectonic structure. It is defined as corner (2) of a hexahedral room as the result of the near encounter between 2 planes or walls at 90°.
  • the corners (1) of a hexahedral or cubical room act as a convergent funnel where the reflection of the sound bounces repeatedly in a short, quick and confused manner; making these zones of the room acoustically critical.
  • the 90° x 90° x 90° corners cause acute sound turbulence where waves suffer ruptures in their flow and rhythmic reflection creating background noise.
  • the Heptagon From the graphic of the regular 7-sided polygon inscribed within a circle or heptagon, the polygon is divided into two equal parts drawing a perpendicular line from the centre of its base, a line that agrees with its superior angle. One of the halves of the heptagon is taken and rotated on its axis 7 times, fixing one half to each point multiple of 51. 43°. Seven concentric meridians in this three-dimensional figure are formed, the basis for the construction of the Irregular Heptagonal Polyhedron - Acoustic Quartz. ( Fig. 2.1 ).
  • each meridian vertex is horizontally joined to its contiguous vertex, this operation results in three horizontal line sequences that conforms the body of the IHP-Acoustic Quartz. ( Fig. 2.2 ).
  • the architectonic structure of the IHP-Acoustic Quartz consists of 45 tubular links that hold 119 beams together.
  • the studio's 23 pipe-like links ( Fig. 9.1 ) also offer the possibility of manipulating acoustics from its interior thanks to its hollow corners and their generous 28 cm. orifice diameter. These links allow for the evacuation of excess sound pressure through the studio's 22 corners, as well as to acoustically manipulating with regards to sound reflections.
  • the structural links of the IHP-Acoustic Quartz are distributed in the following way:
  • the architectonic structure of the IHP-Acoustic Quartz is composed of 22 concentric walls housed within a sphere ( Fig. 4 ); they are distributed in the following way:
  • the IHP-Acoustic Quartz consists of grill-style flooring, a studio designed as a habitat for sound. Due to its polyhydric design we have subjected our to the conditions of the natural spherical sound expansion phenomenon. The conception of the expansion of sound (PointSphere) forms the basis of our studio's architectural design that prioritises the sound's natural necessities as opposed to those of a human dwelling.
  • the grill-style flooring is located midway up the IHP-AQ structure. ( Fig. 8.1 )
  • the IHP-Acoustic Quartz grill-style flooring does not act as a solid floor. Its holes or perforations allow for the passage of sound waves through it; the sound of a musical instrument can travel towards the inferior zones of the studio. In our studio, musical acoustics do not encounter any obstacle in their spherical and free expansion ( Fig. 3.1 ). Sound waves descend until they reach the water base; a zone in which sound is recepted by water. *Aquaphonic Acoustic Action. ( Fig. 12.1 ).
  • the -Healthy Corners- of the Acoustic Quartz All the corners of the IHP-Acoustic Quartz have a generous and obtuse angle of + - 128°.
  • a corner (1) is defined as the 22 edges formed by the interaction of 3, 4 and 7 walls.
  • Each corner in the IHP Acoustic Quartz is distributed in the following way ( Fig. 6.1 ):
  • the IHP-Acoustic Quartz corners have 42 obtuse angles of + - 128°.
  • a corner (2) is defined as the 42 angles formed by it 22 concentric walls in pairs:
  • the IHP-Acoustic Quartz has 23 tubular links whose function as studios' hollow corners allow for acoustic manipulation.
  • the excess sound pressure at the interior of the room can be evacuated through these corners and we are able as well to attenuate sound turbulence relating to the corners:
  • the architectonic structure of the IHP-Acoustic Quartz is characterized in that its form and its construction links can be adapted to the necessities of users: thanks to its links it is possible to alter the size of the structure, and therefore vary its volumetric area ( Fig. 13.1, 13.2 and 13.3 ).
  • the prototype of the IHP-Acoustic Quartz constructed in Quito-Ecuador measures 7.90 meters in diameter.
  • the IHP-Acoustic Quartz has a polyhedral design consisting of a heptagon, a 7-sided polygon; this is why the studio does not present any parallelism between its 22 concentric walls housed within a sphere.
  • the IHP-Acoustic Quartz grill-style flooring allows this spherical reflection phenomenon to occur in the whole volumetric area at its interior.
  • the architectonic structure of the IHP-AQ consists of 45 links holding 119 beams distributed in the following way ( Fig. 14.1 to Fig. 14.14 ): Construction: 23 links supporting 49 beams. Grill-style flooring: 8 links supporting 42 beams. Structural triangulation: 14 links supporting 28 beams. Total 45 links supporting 119 beams.

  • the industrial application focuses on the manufacturing of the 45 IHP-Acoustic Quartz links; allowing the client to easily construct the recording studio and to enjoy priviledged acoustic conditions.
  • the 45 IHP-Acoustic Quartz structural links can be made through artisan welding or conventional techniques using iron or steel smelting in moulds for their serial production.
  • the IHP-Acoustic Quartz recording studio is available to the client as follows:
