1 sight + sound + space = ambience

2 Two senses, one sensation Intimate, Open, Subdued, Lively, Articulate, Engaging, Balanced, Serene These terms could describe the visual aesthetic of an architectural space. Yet these same words also could apply to the acoustical ambience of the same room. Ideally, a room s appearance and acoustical signature work together to common effect. Eye and ear sense a symmetry when a room s aural and visual sensations are in harmony. Achieving this effect, consistently and creatively, is the goal of Libra a vibrant new approach to the art and science of acoustics from Meyer Sound Laboratories. Patented design for spaces large and small The Libra Acoustic Image System is a patented design that ensures results precisely tailored to the venue requirements. All Libra panels meet specified sound absorption characteristics. Libra is constructed with a robust, three-inch extruded aluminum frame with welded corners for uncompromising sturdiness. The frame is specially designed to maintain optimum tension for the high-resolution printed image throughout the life of the panel. The printing process uses only the highest quality inks to ensure the stability of color, contrast and image detail over time. Libra panels are available in four standard sizes from 4' x 5' (1.21 m x 1.5 m) up to an extraordinary 10' x 14' (3.04 m x 4.26 m). Custom sizes are also available. airports retail atria restaurants & bars offices meeting &

3 Artistic Direction: Deborah O Grady The artistic director for Libra is renowned San Francisco Bay Area photographer Deborah O Grady. Known for her stunning landscape photographs, O Grady has exhibited her works at a number of West Coast museums and conference centers. In addition to offering her own images, many on an exclusive basis, O Grady is curating an extensive library of images from associates and other sources. Her valuable consultation will ensure that images selected for Libra will support all other architectural and design elements for optimum visual enhancement of the space. Holistic Sound: Three Elements Libra is the first passive acoustical system from Meyer Sound, a company renowned for more than three decades as a technology innovator in sound reinforcement and active acoustics. Meyer Sound s direct reinforcement systems can be found at Vienna s Musikverein concert hall, in Broadway and Las Vegas productions, and in concerts with artists as varied as the The New York Philharmonic, Rod Stewart and Metallica. Meyer Sound also developed the Constellation acoustic system, a suite of technologies that applies advanced digital processing, ambient sensing microphones and multiple miniature loudspeakers to create variable acoustic signatures with stunningly natural effect. Notable venues employing Constellation include the Svetlanov Concert Hall in Moscow, the Kanbar Forum at San Francisco s Exploratorium, and Nokia Theatre in Tallinn, Estonia. With Libra, Meyer Sound becomes the only company to offer a holistic approach integrating all three elements of sound in enclosed architectural spaces: direct reinforcement, Constellation active acoustics and Libra passive acoustics. conference rooms museums residences manufacturing facilities

4 restaurants, bars and hospitality Restaurants and bars present an extraordinary acoustical challenge. Operators strive to strike the perfect balance between a lively buzz and sufficient intimacy and separation to enable intelligible private conversation. The balance that works at the bar may be inappropriate for tables across the room, and a buzz that is overbearing for a noon business lunch may be insufficient for the late night lounge crowd. With Libra and, when appropriate, Constellation, Meyer Sound offers an acoustically innovative and visually striking solution. for good local intelligibility. When necessary, the effects of Libra can be supplemented by appropriate carpeting, furnishings and acoustically absorptive ceiling treatments. For hospitality venues that wish to vary the acoustical signature of the space, Meyer Sound offers a special variant of the Constellation acoustic system. Working with a relatively subdued acoustic baseline, Constellation allows the operator to dial up the buzz in a subtle manner that maintains an energetic room ambience while still allowing intimate private conversations.

5 Cafés & casual performance spaces The café demands an acoustical signature that is controlled but never lifeless. And when the café doubles as a casual performance space, extra absorption around the stage area and on opposite walls is critical to allow patrons to either listen to the music or carry on intimate conversation. Unlike dedicated performance spaces, where the auditorium is darkened, these casual performance spaces usually maintain ambient lighting at all times. Libra provides the idea solution for rooms where the visual ambience always shares the limelight with the acoustical environment. Berkeley Repertory Theatre Cafe, Berkeley, California

6 Offices & meeting rooms Focus and clear communication are essential when taking care of business. In open office spaces, a relatively dead acoustic dampens unwanted distraction from nearby activities. In boardrooms and meeting spaces, a balanced approach controls excessive reverberations while allowing some early reflections to support intelligibility. In both cases, Libra affords ample options for realizing the desired acoustical effect while complementing the architecture and enhancing the mood desired by the designer.

7 The exceptionally large panels exclusive to Libra allow the designer to make a bold statement to set the mood in an entire room. The large Libra panels can be particularly effective on wall spaces left vacant behind drop-down video screens. Meyer Sound Luna Conference Center, Berkeley, California

8 residential Libra panels are also at home in residential applications. Larger rooms used for entertaining groups benefit from a moderately lively acoustic realized through judicious placement of smaller Libra panels as needed. Home theaters that also double as socializing spaces can benefit from quite large Libra panels, as effective cinema sound demands almost complete absence of room reverberations.

9 Institutional & light industrial Both visual image and acoustical control are critical across a wide range of institution and industrial activities, including scientific research labs, medical facilities, and light fabrication and assembly operations. Acoustical control beyond that mandated by occupational safety regulations improves communication among employees and lessens worker fatigue. The end result is improved productivity. Libra panels provide the added benefit of an inspiring and uplifting visual experience. The quality of Libra imagery reflects the importance a company places on the quality of the workplace experience.
