      The most common reference distance for loudspeaker SPL specifications is 1 meter (3.28 feet). The choice is one of convenience – any distance will do. The 1 m reference simplifies distance attenuation calculations by eliminating the division required in the first step:   Loudspeakers must be measured at a distance beyond which the shape of the radiation balloon remains unchanged. The changes are caused by path length differences to different points on the surface of the device. These differences… View this story

    As with the ever-ongoing debates about “tubes versus transistors,” “analog versus digital” and “Mac versus PC,” there’s not likely to be agreement any time soon about “objective versus subjective” when it comes to sound quality. Extremists in the “Objectivist” camp argue that, “if it can’t be measured, it doesn’t exist” while on the other hand, the “Subjectivist” side firmly backs the idea that “human beings can hear things that can’t be measured.” How often has it been suggested, “use your… View this story

    church sound
    Gary Zandstra 10/03/16 02:25 PM,
    This article is provided by Gary   Sitting in the tech booth during a service on a recent Sunday, I had an “a-ha” moment. Not a big one, but still a good lesson. We had traded worship bands for the day with our sister church. Our band was playing at their place, and vice versa. One of our front of house people, Justin, traveled with the band to do the mixing. Just as our service began, I received a… View this story

    Editor’s Note: Here’s an interesting thread from the PSW Live Audio Board (LAB) forums. It’s lightly edited for grammar and formatting. Enjoy. Posted by Ivan I have been out of the direct rental business for 16 yrs now, so I don’t often see riders anymore-but somebody passed this on to me and I was wondering how often you see this-and how is it “checked”. I totally understand the whole “rider game,” but just wondering if anybody has actually insisted on… View this story

    studio acoustics
    Peter Janis 09/27/16 06:45 AM,
    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

    line arrays
    Jeff Berryman 09/20/16 11:39 AM,
    This is a discussion of line array high-frequency output capability, and what it might mean to you. The specific quantity we’re looking at is the frequency response at maximum output power for all drivers. This is the maximum acoustic output of the array as a function of frequency. I will call it the power-bandwidth response. Here’s a question: what power bandwidth must line array elements have in order to deliver a flat frequency response to audience seats? Because of the… View this story

      The human auditory system is equipped with two inputs - left and right ears. This “binaural” processing system provides us with the ability to localize where sound is coming from, something that a one-eared listener would have difficulty in doing. Playback systems may utilize any number of channels to surround the listener with sound, but two channels is always enough to simulate the human listener. Recording enthusiasts have long discovered the benefits of stereo microphones. While not necessarily “human-like,”… View this story
