Friday, April 05, 2013The Impact That Acoustics Can Have On Sound In Any Room
Pat Brown 04/05/13 08:04 AM,For most humans, there is nothing easier than breathing, seeing, smelling and hearing. We do these things without thought, and even take them for granted. Our senses were given to us to help us exist in a physical universe. They are transducers that allow physical stimuli to be converted into a form recognized by the brain. We are bombarded with stimuli every waking moment, and our brains are continuously processing the information to help us function in our environment. Of… View this post

Monday, April 01, 2013More To Carry: Gig Savers Come In Many Forms
Craig Leerman 04/01/13 06:19 PM,Recently, I detailed a checklist of “everyday carry” (EDC) tools that stagehands should always have on hand at every gig (see it here). It met with such a positive response that I’m going to share additional tools that invariable make me more efficient, and the job a bit easier. While this might seem like a lot to lug around, I’ve found these items to be well worth the added weight and hassle. To simplify transportation, I break them up into… View this post

Friday, March 15, 2013Using All-Pass Filters To Improve Directivity & Magnitude Response
Charlie Hughes 03/15/13 04:29 PM,We are all familiar (or at least should be) with a low-pass and high-pass filter. As the name implies, they pass one part of the audio spectrum while attenuating the others. They are the basis for loudspeaker crossovers. As with any analog filter there is phase shift associated with the change in output magnitude of these filters. Examples of these are shown in Figure 1 (below) as fourth-order Linkwitz-Riley filters. If we were to add the output of these filters… View this post

Monday, March 11, 2013A Rig Of Their Own: Developing A Mobile Church System
Todd Hartmann 03/11/13 07:09 PM,Designing an audio system isn’t always as simple as picking your favorite boxes, throwing some amps in racks, and “firing it up.” While favored loudspeakers might indeed be a starting place, there are vital factors that must be addressed, including the coverage needs of the room, characteristics or obstacles in the room that could be problematic, weight limits with respect to flying components, and so on. Another issue can be the musical “feel” the client is going for. Different loudspeaker… View this post

Friday, March 08, 2013Why Measure A Sound System? A Detailed Look At Where It Matters
Bob Thurmond 03/08/13 02:26 PM,There exists a long list of important sound system characteristics that we have no meaningful way to measure or evaluate. Besides, the really important skill is to be able to listen, identify problems by ear and correct them on the spot, right? But is this realistic or just an elusive dream? Even if problems can be identified subjectively, they still need to be solved physically. Therefore, we must know exactly what, where and how much. These parameters can be learned… View this post

Primer: Acoustic Characteristics Of Live Sound Reinforcement
Tim Vear 03/08/13 02:04 PM,Sound Waves Sound moves through the air like waves in water. Sound waves consist of pressure variations traveling through the air. When the sound wave travels, it compresses air molecules together at one point. This is called the high pressure zone or positive component (+). After the compression, an expansion of molecules occurs. This is the low pressure zone or negative component (-). This process continues along the path of the sound wave until its energy becomes too weak to… View this post
