      The reverberation time (RT) is one of the most fundamental room measurements. It gives a broad brush stroke description of the general acoustical behavior of a space, paving the way for the use of other metrics to determine clarity and direct-to-reverberant ratios. Wallace Clement Sabine was the first to formalize the RT into an acoustic metric. His method of measurement involved a program source, a stopwatch and a quiet room. Sabine determined that 60 dB of room decay was… View this story

    This article is provided by   I have a curmudgeonly hate for modern technology. I like roll-up windows and faucet handles and telling stupid electronics what to do, when, and at what volume. I avoid the automated doors at stores in favor of the pull-handle ones. I think there’s something to human beings, to humans BEING, that technology at its zenith can’t beat. In the world of life, this makes me a dinosaur. In the world of audio, it… View this story

    Audio Precision announces the introduction of their Speech Transmission Index (STI) plug-in for APx500 audio test software. Created for engineers developing public safety (police, fire, emergency) communications and public address systems, as well as flight recorder devices, the APx STI plug-in provides measurement capabilities conforming to international standard IEC 60268-16 (2011). Developed as a method for quantifying the intelligibility of speech with respect to a transmission medium—for example a room, an intercom system, a radio link—STI is an objective measure… View this story

      When most people think of sound reinforcement systems, or audio systems in general, they rarely do so with regard to speech intelligibility (SI). It’s usually about the music, with the assumption that if a system sounds good for music, it should work for speech. While this can be true in small, well-behaved rooms, it is seldom true in large spaces. My first sound system disaster was the design and installation of a large, expensive sound system that failed to… View this story

    As audio engineers, we’re constantly presented with choices that involve compromise and give and take. Many of these are budgetary and/or based on realities of what’s available or possible for a given application. Tradeoff, TANSTAAFL and triage are underlying principles to my decision-making process in the design and optimization of sound systems. The concept of the tradeoff is simple: give up something to get something. TANSTAAFL is an acronym created by sci-fi writer Robert Heinlein: “There ain’t no such thing… View this story

    Martin Audio has announced an upgrade to Display, the software brain of the MLA Series. Display is the numerical optimization process that eliminates trial-and-error tuning sessions, so that an MLA Series system achieves the required audience coverage. Based on an acoustic model of array behavior, it gives a prediction of the direct sound produced over the audience as well as areas where sound is to be minimized. It takes the guesswork out of array design, deployment and control ─ generating… View this story
