    Part one in this series is available here. We need to consider the real, long-term sound pressure level capability of today’s sound reinforcement systems to make sure they’re not being operated at levels where the components are stressed or where they won’t sound good. While acoustic design programs do a good job of predicting how the system will perform in a given room, the system designer must determine what the goal is for each application. What SPL Is Not SPL… View this story

    Before beginning the design process for a business sound system, identify what the customer needs and expects: Fidelity Expectations. Does the client want a good, basic system; something a little better than average; or maximum bandwidth and maximum fidelity? Sound-Level Requirements. Will the system be used strictly for background music, or does it really need to rock? Usage. What kind of music will be played through it? For example, if it’s urban funk, then you’re going to have to think… View this story

    db reference chart
    Pat Brown 06/24/14 06:32 AM,
      Increasingly, SynAudCon has been doing audio training for industries outside of mainstream audio. These include fire alarm, security and IT. Practitioners in these fields are being dragged “kicking and screaming” into the professional audio world. The concept most difficult for them to grasp is the decibel. Our task is to convey a working understanding of the dB in the shortest possible time span. In a one or two-day class, there is simply no time for an in-depth discussion of… View this story

    As sound reproduction has transitioned to the digital realm, audio professionals have a wealth of capabilities that were unthinkable in the analog days. Today, loudspeakers with companion digital processors are increasingly a tool of choice, going well beyond just the higher end of the application spectrum. Virtually all types and brands of digital loudspeaker processors offer a rich suite of features, often overwhelmingly so. Some have capabilities that are unique, while others seek to capture the most important functions at… View this story

    Analog? Digital? Both? In professional audio, many choices exist, but there’s not enough time to make the wrong ones. We regularly hear claims floating about, often skewed by particular opinions and interests that tend to color underlying simple truths. The Merriam-Webster Dictionary defines the noun “analog” as being something that is analogous (similar or related) to something else. For example, an analog can be a food product that represents another, such as inexpensive whitefish “krab” intended to replicate more expensive… View this story

    subwoofers
    Craig Leerman 06/06/14 08:49 AM,
    Today’s music and special effects (like explosions in motion picture soundtracks) include a lot of low-frequency content. While larger full-range loudspeakers may have a wide frequency range, it takes subwoofers to really reproduce low end with impact, especially for bass-heavy music like electronic dance (EDM) and reggae. Deployment of main loudspeakers is usually a relatively straightforward matter, but locating and configuring subs presents numerous options and can be a bit of a challenge. Let’s start with the basics. Subwoofers are… View this story

    Hal Leonard Books has published Behind The Boards II: The Making of Rock ‘n’ Roll’s Greatest Records Revealed, which takes readers inside the studio to experience the creation of still more legendary rock gems, following up where the initial volume of Behind the Boards left off. In Behind The Boards II, author Jake Brown covers “Hotel California” by the Eagles; “Should I Stay or Should I Go?” by the Clash; “Rocketman” by Elton John; “Ziggy Stardust” by David Bowie; “Start… View this story

    In a previous article (“Loudspeaker Sensitivity”), I examined the topic of loudspeaker sensitivity and how it may or may not relate to the overall sound pressure level (SPL) produced by a loudspeaker. One of the conclusions of that article is that the SPL produced will be dependent on the spectral content of the signal driving the loudspeaker. Thus, having knowledge of the driving signal (i.e., program material) or being able to make an educated assumption about it may aid in… View this story

    Trap boxes and line arrays get all the attention. And that’s no surprise—they’re big and loud, and dare I say it, glamorous. But the truck rarely rolls without a complement of two-way loudspeakers sporting a 12-inch or 15-inch woofer and a horn. Whether its monitor wedges, drum fill, front fill or just “speakers on sticks,” small 2-way boxes do many of the everyday jobs that make up a typical sound reinforcement day. We take the performance of these boxes for… View this story

    Today’s projection technology provides tremendous flexibility for locating the projector with respect to the screen. There are two techniques, applied individually or in combination, that deliver this installation flexibility. They are: 1) Lens Shift 2) Electronic Keystone Correction For Lens Shift, the primary enabling component is the projection lens. The physics of a convex lens dictate that an accurately focused image exiting the front of a lens will “shift,” based on the introduction of vertical or horizontal movement of the… View this story
