    For the majority of humans, there is nothing simpler than listening to sound. You simply, well, listen. When it becomes necessary to describe the listening experience analytically, however, a host of complex equations and diagrams are required to describe even the simplest of sonic events. The benefit of mathematical analysis is that it can yield insights that are not apparent through intuition alone. Acoustic signals are easily measured, and the audio components that produce them have characteristics that can be… View this story

    What Damping Does: The main effect of damping in a loudspeaker is to reduce the SPL produced by the loudspeaker’s diaphragm moving because of its own inertia after the signal stops. The frequency of the sound it produces with this movement will be at the resonant frequency of the moving system. A common term for this is “overhang,” and in severe cases, this can translate into “one note bass.” Types Of Loudspeaker Damping: There are two types of loudspeaker damping:… View this story

    live sound

    Editor’s note: Following is an interesting discussion from the Live Audio Board (LAB) here on ProSoundWeb. It’s been lightly edited for space and consistency only. Question by Sean Thomas: I’m doing some research on buying a new line array system. I’ve looked at 10-12 different brands and models, and have graphed a bunch of specs on paper so I can keep track of them all. I found that one brand is 1,500 watts RMS and 136 dB peak output, a… View this story

    speaker distortion
    Michael MacDonald 02/01/13 11:24 AM,
    Almost everybody in the pro audio business is a specification or “spec” junkie. From folks on the recording side to the sound reinforcement practitioners, we all want every detail of the technical performance of every piece of equipment in a system. Specs seem extremely important, particularly those that represent a numerical improvement from past products, which are heralded as an advantage.  But man cannot live by specs alone. Quite often, those who turn to specifications to answer questions should instead… View this story

    power amplifiers
    Tommy O’Brien 05/24/12 08:11 AM,
    Now that Class-D power amplifiers are common in professional audio, much attention has been directed toward their performance compared to conventional analog amplifiers. Let’s briefly address the question of what Class-D means in order to clear up any confusion, because marketing people have conjured up several fictitious designations. An amplifier that uses its output devices as switches is Class-D. It’s as simple as that. Everything else is analog, so “analog amp” means “not a switching amp.” The phrase “conventional amp”… View this story
