    In a city with no shortage of museums (New York City), the Intrepid Sea, Air and Space Museum is truly one of a kind. Founded in 1982 as a final home for the historic aircraft carrier USS Intrepid, the museum’s treasures now include the world’s fastest commercial jetliner, the British Airways Concorde; the first space shuttle, Enterprise; and the USS Growler, the only American diesel-powered strategic missile submarine open to the public. More than a million visitors every year tour… View this story

    Auralex Acoustics has introduced SoniCell acoustical panels, a cost-effective 1-inch treatment with high absorptive properties that provides a way to improve speech intelligibility in environments needing Class A fire-rated materials. Light weight and easy to handle, SoniCell panels are available in either white or a charcoal gray color that blends into many dark open architecture commercial ceilings. The panels are well suited for environments such as nightclubs, restaurants, gymnasiums, recording studio live rooms, multi-purpose rooms, industrial facilities and more. Specs… View this story

    studio acoustics
    Peter Janis 04/30/14 03:12 PM,
    This article is provided by Primacoustic   Just like large big commercial studios, smaller and home studios suffer from acoustical interference that can make it more difficult to mix, especially when surrounded with the sound effects and ambiance that now typifies today’s stereo and 5.1 surround sound mixes. In professional studios, the walls are strategically treated with fabric-covered absorptive panels on the sides, front, rear and sometimes on the ceilings. The key to improving intelligibility (or our ability to discern… View this story

    If one could listen to only the direct sound of a loudspeaker, the world would be a very different place! Unfortunately, free field listening, where you have no reflections, room modes or ambient noise, is hard to achieve in everyday life, so we listen to loudspeakers in real rooms. The interaction of a loudspeaker system and a room can be very complex to understand, model or measure! One way to measure this interaction is to measure the impulse response of… View this story

    sound
    Neil Thompson Shade 03/31/14 01:28 PM,
    Let’s have a look at sound particles, acoustic pressure, propagation medium density, particle velocity, acoustic energy, volume velocity, and acoustic impedance. Abstract concepts? Nope—far from it. All are related to the physics of sound propagation in an elastic medium that result in changes to the displacement, pressure, density, temperature, and velocity within the medium. In other words, this is at the basis of everything we hear, the scientific essence of sound. Sound Particles. Sound requires a medium for the transmission… View this story

    At the Berner Rathaus (English: Bern Town Hall) in Switzerland, voice intelligibility has been greatly improved with the installation of two steerable Meyer Sound CAL 64 column array loudspeakers. The system is implemented in the Grossratssaal, the acoustically challenging main legislative chamber of the 15th century Gothic structure. Project design was handled by Daniel Zurwerra of Suhr, Switzerland-based Virtually Audio. “Voice reinforcement in this space is challenging for several reasons,” recounts Zurwerra.  “First, the reverberation time is more than two… View this story

    Saint Louis University’s newly opened Center for Global Citizenship is both a practical initiative to bring several campus services under a single roof, and a strongly symbolic move that represents the school’s commitment to its internationally diverse student body, drawn from 101 nations around the world. When this wide-ranging group assembles in the new Center, it receives powerful and highly intelligible sound provided by RoomMatch loudspeakers and PowerMatch amplifiers from Bose Professional Systems. TSI Technology Solutions, a division of TSI… View this story

    measurement
    Pat Brown 03/13/14 02:42 PM,
    Many audio field technicians are now in possession of measurement systems that can be used to assist the listening process in equalizing sound reinforcement systems. But, they’re often surprised to find that the measured system response correlates poorly with subjective impression of how the system sounds. In other words, the system can sound good when it looks bad on the analyzer, and it can sound bad when it looks good on the analyzer. As a result, some users have become… View this story

    Opened in 1998, Benaroya Hall in Seattle hosts one of the last concert halls—the S. Mark Taper Foundation Auditorium—to be built in the U.S. that was entirely devoted to the acoustic delights of a full orchestra; as such it has in recent years fallen foul of the irresistible movement towards multipurpose concert venues. As Mark Turpin from acoustic consultants Jaffe Holden (Norwalk, CT) points out, “You can’t build concert halls like that anymore; it’s just not financially viable.” The nub… View this story

    How many sound systems are in use? Many millions, for sure, and they’re found in all types of venues and for all kinds of programs. So one would think we’d know exactly how to do it by now. But there seems to be plenty of examples to prove that we don’t. Why should this be? What is it we don’t yet understand? Do we even know enough to know what we don’t know? Perhaps we should start by trying to… View this story
