Adam Shulman 02/13/12 07:46 AM,The term optimization stems from the French word optimisme, meaning “the greatest good” or “the best.” Historically, the sound reinforcement industry has employed the term in the context of sound system tuning or alignment, but it was not until recently that the use of the term optimization has taken on a more literal and formalized meaning. It’s important to be familiar with the concept of numerical optimization (most simply, the determination of input values to obtain a function’s maximum or… View this story

Pat Brown 01/23/12 02:15 PM,It is difficult to describe how something sounds. The terms are vague and subjective, and often have different meanings to different people. Sound is meant for listening, and the listening process is the most power diagnostic tool for the audio technician. Measurement systems yield lots of data, but it can be difficult to interpret. It makes perfect sense to combine the hearing process with the measurement process, allowing the benefits of each to be exploited. The process of convolution allows… View this story

Mike Sokol 01/12/12 09:30 AM,This article is provided by How-To ASSIST Technical Training. If you’ve attended a HOW-TO Sound Workshop, you’ve heard me play examples of loudspeakers out of polarity. You can lose bass response, cancel your vocals and cause general phase mayhem in your sound system. Well, here’s a cheap and easy way to test for proper wiring inside your loudspeaker cabinets before you install them up on the wall and without running any audio signal through them. See below for Thumper,… View this story

Gary Zandstra 09/26/11 04:45 PM, 0 CommentsRecently I’ve been discussing the more technical side of sound pressure levels as well as elements of musical style and our perception of levels, but there’s another aspect I’ve been thinking about with respect to this topic. When does sound level come into play to make a Sunday morning service a performance rather than a participatory event? Dann, the senior pastor of the church I serve at, has on a couple of occasions said, “I think we went past participation… View this story

John Murray 09/01/11 02:05 PM,When last we left off, you had just acquired a 3-D, FFT -based measurement system and were ready to use it to tune a sound system. (Click here to view the previous article.) So let’s get to it! The first thing to do is place the calibrated measurement microphone on a mic stand in the middle of the listening area, turn on all of the system’s loudspeakers and turn up the test signal, just as is done with a real-time… View this story
