Patented Oct. 4, 1932 This invention relates to studios or compartments :intended to be used for picking up sound impulses and translating them 'into energy'lfor recording or for -radio broadcasting purposes. f i "A'Instudios of this character itis impor- Itan't"`that the sound impulses, as heard by the performers within the room, should'possess naural naturalness and must not `be blurred or'fconfused by improper reverberation. It is common practice in such studios tol provide means which will absorb all sound impulses which may be reflected back to the pick-up device.- AThe means, however, at present employed so completely absorbs reiiected sound waves'that an unnatural effect is produced within the studio and this unnaturalness is a moreor less annoying or disturbing agent tothe performers. j

One object of this invention is toprovide a studio of the character described wherein means are providedl to render the sounds created within the studio, with aural naturalness to the performers. 'l f Another object of this invention is to provide' a Vstudio 'ofthe character described wherein means are' provided to give proper amplification to the sound impulses 'as they impinge on the l'pick-up device. f y

I"Another object of'this invention is to provide, in a studio of the character described, upon the floor, ceiling and certain walls of thestudio, means yfor absorbing certain sound waves toprevent a too prolonged reverberation. I i A further yobject is to provide a studio as described, Whe-rein the direct sound Waves o-rji'mpulses are suitably amplified to the pick-upl device and means are provided to impart resonance to the said sound waves.

A further object is to provide a studio of the character described wherein ample provision is made for Ventilation land the 'exclusion of extraneous noises. A, y. These objects are attained by the means illustrated in the accompanying drawing,

which form a part of this application and in which: s

Figure 4 is a detail view, in section; of a Ventilatingy outlet inthe ceiling of the studio. IFigure `-51is detail plan showingafsection of a wall of the studio having a Ventilating corridor around the walls 'of said studio. i

Figure 6 is a longitudinal 'section of a studio showing a slight modication which will be hereinafter explained.' fe f: Figure 7 is a plan view of same. v"All the illustrations are diagramatic inasmuch as no lattempt is made to show any detail of'construction.. x l Referring in more detail lvto, the parts, 1 designates a room in which the surfaceof the floor and ceiling, 2 and 3 respectively, are I a smooth, approximately parabolic surface 7.

The floor 8 of said recess is alsovof rigid construction and is finished With a smooth soundreiecting surface f ci 'ff/ivm .Following the contourvof said recess, but arranged a fewr inches therefrom is a shell 9 of suitable wood construction, which, with the Wood floor 10, forms a performersnich 11; the said shell and floor are capable of sympatheticvibrations. ,a

The floor 10 of said niche 11 is raised,a few inches, above the rigid floor 8 to form aniairspacevor chamber. 12 which, with the air space 13 behind the shell 9, forms va reso.- nating chamber, open at the ends 14 and'l.

A pick-up device 16is placed at the approximate focal point to the parabolic shell.

The said niche 11, which will hereinafter be termed a sound-niche is not limited to the size, of .the end of the studio, but may ybe upon the pickup device Will pass on to vthe sound absorbing surfaces and no reflected sound Waves other than those from the soundniche Will strike the pick-up. W

The resonance imparted to the sound Waves 'or' impulses Will give a greater degree ofnaturalness than has heretofore been possible.

The pick-up device may be rigidly mounted upon a rigid base block as l7 and the pedestal portion may be incased with sound absorbingmaterial. v

1 'Openings 18, providing means of ingress and egress vare provided and are shielded against sound ingress by means of partitions or Walls 19 and 20 which are constructed of or are covered with a sound absorbing material and function as baflles to prevent the ingress of extraneous sounds and the egress of studio sounds.

An air outlet 21, (Figure 4), may be provided in the ceiling Which leads to a chamber 22 having an outlet 23, and series of baflles 24 and 25 interposed between the outlets 2l and 23. The Walls of said chamber and outlet passage 21 and said baflles 24 and 25 areconstructed of or covered With suitable sound absorbing material. 1 v Y A similar chamber having baffles properly insulated against sound reflection is provided at the air inlets which maybe located at either side of the sound-niche asat 26 and 27, shown in Figure 3. ..1

Other provision for ventilation may .be provided by means of a corridor 28, (Fig ure 5), Which may parallel one or more sides of the studio.V 7

The said corridor leads from any point outside tliestudio to the studio entrance opening 18, and interposed between these tWo points are series of staggered partitions 29 and 30. The Walls of the corridor and all of the baffles are constructed of or are covered with a-sound absorbing material. AVWindoW 31 opening to the outer atmosphere may be provided in the said corridor.

In Figures 6 and 7 a modified form of sound shell is shown and is applicable to small studios.

In this form the sound niche has a straight back Wall 3l and beveled ceiling and side lWalls 82 and 33, respectively. The floor,

ceiling and Walls of this modified soundniche are constructed of resonating Wood and the rigid Walls of the recess around the soundniche and the floor of same are iinished with a smooth sound reflecting surface.

The illustrations show a rectangular room but a studio constructed along the lines herein set forth may be oval shaped or circular in plan, inl which case :the sound niche may be placed at anyipoint in the, Wall.- Furtlier the ceiling may be boweled or of any desired shape or -contour provided same is insulated againstsound reflection.

Various modifications may be employed in this invent-ion Without departing from the "spirit and scope of saine and it is therefore notintended tolimitsaid invention to the particular yembodii'iients shown and described.
