Description

A SOUND DEFLECTING ASSEMBLY FOR USE IN SOUND ROOMS
TECHNOLOGICAL FIELD AND BACKGROUND
The present invention is in the field of sound rooms (e.g. recording studios) and relates to a device and method for managing sound propagation in the sound room.
Sound room, such as sound studio at times called "recording studio", is a specialized facility for sound recording, mixing, and audio production of instrumental or vocal musical performances, spoken words, and other sounds. The sound studio typically includes a "studio" or "live station" equipped with one or more sound sources (microphones and mic stands) where the sound to be played is originated, and a control station which is a work station including inter alia professional-grade mixing console(s) to mix, manipulate (e.g., by adjusting the equalization and adding effects) and route the sound for analogue recording or digital recording. Recording studios may include an isolation booth, which is a standard small room in the recording studio, and is typically soundproofed to keep out external sounds and keep in the internal sounds, and is designed to reduce the amount of diffused reflections from walls to make a good sounding room.
GENERAL DESCRIPTION
One of the common problems associated with the sound quality achievable in sound rooms relates to back reflections of sound waves, originated at sound sources, towards said sound sources from various interfaces and mainly those of the equipment facing the sound propagation direction, e.g. the equipment typically existing in the sound studio (control station).
In particular, when sound waves generated by a sound source are reflected from one or more surfaces / interfaces of a working / control station, typically directly exposed to the sound waves, towards the sound source, such back reflected sound waves interact (e.g. superpose and/or interfere) with the original sound, thus imposing noise onto the original sound. Consequently, the resulting sound waves reaching the listener have reduced quality due to undesirably low SNR.
In view of the above, there is a need in the art for a novel sound deflecting assembly configured for incorporating it with a support structure / panel (which may or may not be associated with a working/control station) facing sound source(s) in a sound room.
It should be understood that the present invention is not limited for use in a recording studio. Moreover, the invention is not limited for use in a closed space. Therefore, the term "sound room" or "sound studio" or "recording studio" used herein should be interpreted broadly covering closed- and open-space environment in the vicinity of the sound source(s).
The present invention provides such sound deflecting assembly, which is configured such that it deflects the original sound waves coming from the sound source in one or more directions away from the sound source, thus preventing or at last significantly reducing the effect of superposition between deflected and incoming (original) sound waves. On the other hand, the sound deflecting assembly of the present invention is configured to minimize absorption of the sound waves by said assembly, thus attenuating sound information losses of the original sound.
The configuration of the sound deflecting assembly of the present invention allows its incorporation / integration with a support structure / panel of any suitable configuration. Such support structure / panel may be a stand-alone unit to be placed in the sound propagation direction from the sound source(s) to be upstream of various other equipment whose surfaces would otherwise interface the sound and thus present the source of noise affecting the quality of sound to be achieved. Alternatively, the support structure / panel carrying the sound deflecting assembly of the present invention may be part of or mounted on the existing equipment directly exposed to the sound source(s).
Considering for example a typical arrangement of a recording studio, there is a working / control station (carrying electronic consoles) located opposite to a sound source (e.g. loudspeakers), such that it is located in a general propagation direction of the original sound waves thus being directly exposed to the original sound waves. Accordingly, the surfaces / interfaces of the working/control station present the main source of noise affecting the quality of sound to be achieved. The configuration of the sound deflecting assembly of the present invention allows its incorporation / integration with a working / control station of any suitable configuration.
In the description below such station is referred to as a "control station", but this term should be interpreted broadly including any typical equipment used in a sound room directly exposed to original sound propagating from the sound source, as required for the studio operation. Moreover, as mentioned above, such control station generally constitutes (exemplifies) a support structure / panel.
More specifically, the sound deflecting assembly, or at least some elements thereof, can be attachable or integrally made with one or more support structure / panels of such a control station. The sound deflecting assembly, while being of a relatively simple configuration easily implementable with a control station, allows for significant improvement of the sound quality in a sound room.
According to one broad aspect of the present invention there is provides a sound deflecting assembly for use in a sound room at a location in a path of a general propagation direction of sound being originated in one or more sound sources in the sound room. The sound deflecting assembly comprises at least one elongated volumetric structure having an elongated proximal base facet, configured for mounting on a support structure located in said path of the general propagation direction of the original sound, and an opposite elongated distal non-planar surface by which the elongated volumetric structure is to be directly exposed to the original sound. The configuration is such that the elongated volumetric structure, when mounted, by its proximal base facet, on the support structure projects from the support structure, and the distal non-planar surface thereof intersects with said general propagation direction of the original sound, thereby deflecting the incident original sound waves, to which said elongated volumetric structure is exposed, towards propagation directions along axes forming non-zero angles with said path of the general propagation direction.
The elongated volumetric structure can be made at least partially solid (monolithic) or, alternatively, can be at least partially hollow structure. In some embodiments, the elongated volumetric structure is oriented such that a longitudinal axis thereof is substantially perpendicular to the general propagation direction, while being either vertically or laterally oriented.
In some embodiments, the sound deflecting assembly includes an array (one- or two-dimensional) of the elongated volumetric structures, which may be of similar or different shapes.
The elongated volumetric structure has a cross-sectional geometry defining the proximal facet and the distal non-planar surface, where the cross-sectional dimension of the elongated volumetric structure may be substantially the same along the longitudinal axis of the structure. Alternatively, or additionally, one or more of the elongated volumetric structures may have cross sectional dimension varying along the longitudinal axis of the structure defining relatively wide and relatively narrow end portions. In the latter case, the configuration is such that the relatively wide and relatively narrow end portions of the structure are located at opposite sides of the path of the general propagation direction of original sound.
For example, the elongated volumetric structure(s) has/have a polygonal cross- sectional geometry defining the proximal facet and the distal non-planar surface. In some embodiments, the distal non-planar surface of the elongated volumetric structure by which it intersects the path of the general propagation direction of the original sound is formed by the elongated surface of a corner element defined by the polygonal cross- sectional geometry of the structure. The polygonal cross-sectional geometry may be in the form of a triangle, defining the proximal base facet of planar geometry by a base of the triangle. In some other examples, the elongated volumetric structure has the cross- sectional geometry in the form of a segment of a circle or oval, defining a substantially planar geometry of the proximal base facet.
As indicated above, the elongated volumetric structure of the sound deflecting assembly of the present invention is configured to be substantially non-absorbing for sound waves. This is defined by the material composition of the structure and the density material within the structure (degree of porousness). For example, the elongated volumetric structure(s) is/are made of any one of the following materials: rubber, concrete, wood, silicone, as well as may be configured as medium-density fiberboard (MBF) structure.
Preferably, the sound deflecting assembly of the present invention further includes at least one pair of first and second elongated plate-like structures located at opposite sides of the at least one elongated volumetric structure, respectively. The arrangement is such that the first and second plate-like structures of the pair extend along the longitudinal axes of the respective elongated volumetric structure and are inclined towards said elongated volumetric structure defining cavities in between each of these plate-like structures and the elongated volumetric structure for trapping, at least partially, the sound waves entering said cavity.
In some embodiments, the cavity defined as described above includes soundproofing material, e.g. is filled by such material. The sound-proofing material may include one or more of mineral wool, rock wool, fiberglass, polyester, PVC (poly-vinyl chloride), polyurethane foams and plywood.
According to another broad aspect of the invention, it provides a control station for use in a sound room comprising a structure intended to be located in a path of a general propagation direction of sound waves being originated in one or more sound sources in the sound room, and the sound deflecting assembly configured as described above and mounted on said structure such that the elongated distal non-planar surface of each of the at least one elongated volumetric structure is directly exposed to said sound waved propagating in the general propagation direction..
The elongated volumetric structure(s) may be integrally made with said support structure of the control station.

DETAILED DESCRIPTION OF EMBODIMENTS
Reference is made to Fig. 1, which schematically illustrates the configuration and operational principles of a sound deflecting assembly 10 of the present invention. As can be seen, in a typical sound room 100, sound waves SWorig are originated by one or more sound sources 102 (e.g. loudspeaker(s) or any other electronic transducers) and propagate in a general propagation direction D. Further typically provided in the sound room 100 is a control station, which includes inter alia recording console(s) used to add (combine or sum) multiple inputs into one or two outputs, complete with level controls on all inputs as well as routing and monitoring capabilities designed to get signals on and off of one or more recording machines. In order to properly perform all these functions, the control station is located opposite to the sound source(s), and is thus directly exposed to original sound waves where the SWorig.
According to the invention, a sound deflecting assembly 10 is provided being located in the path of the general propagation direction D in front of or within the control station, such that the sound deflecting assembly is directly exposed to the original sound waves SWorig.
Generally, the sound deflecting assembly 10 is configured for allowing its integration/incorporation with the control station. As illustrated schematically in the figure, the sound deflecting assembly 10 is located on a support structure 20 of the control station.
The sound deflecting assembly 10 includes at least one elongated volumetric structure, generally at 10a - two such elongated volumetric structures being exemplified in the figure. The structure may be (at least partially) solid/monolithic or (at least partially) hollow structure.
The structure 10a has an elongated proximal base facet 12 and an opposite elongated distal non-planer surface 14. It should be understood that the terms "proximal" and "distal" are relative terms, and the distal part/surface of the structure 10a is that by which it faces the sound source location. Typically, proximal base facet 12 is adapted for mounting the volumetric structures 10a on the support structure 20 such that the elongated volumetric structure 10a, when mounted, by its proximal base facet 12, on the support structure 20, projects from the support structure 20. Thus, considering the sound deflecting assembly associated with the support structure 20, the terms "proximal" and "distal" are used with respect to the support structure 20.
Thus, the distal non-planer surface 14 of the elongated volumetric structure 10a intersects with the path of the propagation direction D, and is thus directly exposed to the original sound waves SWorig. The non-planarity of this surface 14 results in that the sound waves SWorig incident thereon are deflected towards propagation directions along axes which form non-zero angles with the general propagation direction D of the original sound waves SWorig. Consequently, interaction between the original sound waves SWorig and the deflected sound waves SWdefl is prevented or at least significantly reduced.
Further, the elongated volumetric structure 10a is preferably configured as a nonabsorbing structure for sound waves. This is defined by the material composition of the structure and the material density within the structure (degree of porousness). For instance, the elongated volumetric structure 10a can be made of any one of the following materials: rubber, concrete, wood, silicone, as well as may be configured as mediumdensity fibreboard (MBF) structure.
The elongated volumetric structure 10a is oriented such that a longitudinal axis thereof is substantially perpendicular to the general propagation direction D. For example, the longitudinal axis of the elongated volumetric structure may be either vertically or laterally oriented.
In some implementations of the present invention, the sound deflecting assembly 10 can include more than one elongated volumetric structure, e.g. can include one- or two-dimensional array of the elongated volumetric structures, which can be of similar or different shapes (i.e., defining similar or different cross-sectional geometries).
Thus, the present invention provides a novel sound deflecting assembly configured for deflecting the original sound waves incident thereon in one or more directions away from the sound source (i.e. deflecting directions non-parallel to the sound general propagation direction). By this, an effect of superposition (interference) between the deflected and incoming/original sound waves is minimized and thus does not affect the quality of the sound being recoded. Furthermore, as indicated above, the sound deflecting assembly is configured as substantially non absorbing for sound waves, thus not affecting the original sound intensity. As a result, the quantitative and qualitative parameters/conditions of the sound being recorded are desirably maintained.
Preferably, the sound deflecting assembly of the present invention further includes first and second elongated plate-like structures located at opposite sides of the volumetric structure(s), respectively. The plate-like structures extend along the longitudinal axes of the volumetric structure(s) and are inclined towards the volumetric structure(s) defining cavities in between each of the plate-like structures and the adjacent volumetric structure. By this, at least a part of the sound waves entering the cavity becomes trapped therein. Such cavity may include (e.g. filled by) sound-proofing material(s).
Reference is made to Figs 2A and 2B, schematically illustrating two specific nonlimiting examples of the sound deflecting assembly 10 of the present invention. In order to facilitate illustration and understanding, the same reference numbers are used to indicate components that are common in all the example of the invention. In these examples, the sound deflecting assembly 10 is shown as including a plurality of the elongated volumetric structures mounted on a support structure 20 which may be a part of a control station in any suitable arrangement.
In the example of Fig. 2A the sound deflecting assembly 10 includes an array 22 of the volumetric structures 10a mounted on the mounted on 20. The structures 10a are configured and oriented in an oppositely symmetrical lateral arrangement, such that the common longitudinal axis L of the elongated volumetric structures 10a is substantially perpendicular to direction D. It should be understood that, generally, the volumetric structures, being either identical or not in sizes and/or shapes, may be solid or hollow, and may be arranged in a spaced-apart relationship in one-dimensional array extending along a horizontal axes.
In this example, each elongated volumetric structure 10a is associated with a corresponding pair of plate-like structures 30 located at opposite sides of the structure 10a. The plate-like structures 30 are, by their one facet, mounted on the support structure 20 extending along axes substantially parallel to the longitudinal axes L of the volumetric structure(s), and project from the support structure 20. The plate-like structures 30 are spaced from the volumetric structure defining the above-described cavities 15, each between the plate-like structure and the adjacent volumetric structure 10a. Although not seen in the figure, the plate-like structures 30 are inclined towards the volumetric structure 10a defining cavities in between each of the plate-like structures and the adjacent volumetric structure. As described above, the cavities 15 may be filled with one or more sound-proofing material(s), such as mineral wool, rock wool, fiberglass, polyester, PVC (poly-vinyl chloride), polyurethane foams and plywood.
In the example of Fig. 2B, the sound deflecting assembly 10 includes a plurality of elongated volumetric slid structures 10a arranged in lateral and vertical arrays 22 and 24. Also, a pair of opposite plate-like structures 30, configured as described above, is provided at opposite sides of and spaced from a region of the support structure 20 on which the structures 10a are located, defining the cavities 15.
Referring to Figs. 2C and 2D there are illustrated two specific non-limiting examples of configuration of the elongated volumetric structure 10a suitable to be used in the sound deflecting assembly of the present invention. The volumetric structure 10a has proximal facet 12 (typically substantially planar facet, enabling its attachment to a support structure) and distal non-planar deflecting surface 14.
In the example of Fig. 2C, the volumetric structures 10a has a polygonal cross- sectional geometry - triangle in the present example. The distal non-planar surface 14, by which the elongated volumetric structure intersects the path of the general propagation direction of original sound, is formed by the elongated surface of a comer element 19 defined by the polygonal cross-sectional geometry of the volumetric structure. In the example of Fig. 2D the volumetric structures 10a has cross sectional geometry in the form of a segment of a circle or oval.
As also exemplified in Figs. 2C and 2D, and can generally be implemented in any other suitable configuration of the elongated volumetric structure of the present invention, the volumetric structure 10a includes at least one and preferably a plurality of inner cavities/grooves 18 arranged in a spaced-apart relationship along the volumetric structure. The cavity /groove 18 extends from the outer non-planar surface 14 towards the inside of the volumetric structure, possibly up to the proximal facet 12. Although in the example of Fig. 2C the cavities are shown as being arranged symmetrically with respect to the edge/top of corner 19, the invention in this configuration is not limited to such symmetry condition.
In any suitable configuration of the elongated volumetric structure of the invention, it may have the same or varying cross-sectional shape/geometry along the longitudinal axis of the structure.
Reference is made to Figs. 3A and 3B which show two different views of the exemplary sound deflecting assembly 10 of the present invention. The illustrations are self-explanatory: The sound deflecting assembly 10 is configured for mounting on / integrating with the support structure 20 (e.g. support structure / panel of the control station), and includes the elongated volumetric structure 10a and first and second elongated plate-like structures 30 located at opposite sides of the elongated volumetric structure 10a and being inclined towards the structure 10a to form cavities 15 therebetween. The elongated volumetric structure 10a includes an elongated proximal base facet 12 by which it can be attached to the support structure 20 and distal non-planer surface 14 by which the volumetric structure 10a is exposed to the original sound waves.
As described above, the cavities 15 between the plate-like structures 30 and the volumetric structure 10a causes trapping of at least a part of the sound waves directly entering the cavity 15 as well as reflections of these sound waves from the facets / surface portions of the volumetric structure 10a and the plate-like structures 14. The sound deflecting assembly 10 may further include soundproffing material(s) located in the cavities 15 filling the space between the plate-like structure 30 and the volumetric structure 10a.
Fig. 4 exemplifies a control station 110 carrying a sound deflecting assembly 10 integrated therein which can be used in a sound room 100. The control station includes a support structure 20 by which the control station is exposed to sound waves originated in one or more sound sources 102 and propagating along a path of general propagation direction D. The sound deflecting assembly 10 includes an elongated volumetric structure 10a and preferably also elongated plate-like structures (not shown) at opposite sides of the structure 10a as described above.
Thus, the present invention provides a simple and effective solution for improving the qualitative and quantitative parameters of sound being recorded in a recorded studio. The sound deflecting assembly of the present invention can be mounted on / integrated with a support structure being part of any station / console typically used in the sound room.
