Summary
One topic that comes up quite often on Audio Branding is audio technology, and how far it’s come over just the last few years. Whether it’s choosing the right sound equipment, deciding if you should record with noise cancellation turned on (and just for the record, you shouldn’t), or taking advantage of advanced recording options like 3-D audio and Dolby Atmos, there’s a lot to consider when it comes to sound. But you might be surprised to learn that the science of sound optimization is a lot older than surround sound, or stereo recordings, or even audio recordings at all. Sound has been a part of our lives for as long as we’ve been around, and it turns out that we’ve been finding ways to boost sound quality and reshape the acoustic landscape around us for just as long. From ancient Roman amplifiers to prehistoric boulder harmonies, our ancestors explored the possibilities of sound in ways that scientists today are still trying to understand. Creating just the right sound experience can be a big enough challenge for modern-day concerts and movie theaters. How do you do it when you don’t have any microphones or speakers? This was the problem faced by Greek and Roman architects, and the science of archaeoacoustics, of how sound was shaped and used in ancient times, hasn’t entirely unraveled their solution. According to the ancient Roman architect Vitruvius, they used “acoustic jars,” or “echea” in Greek, small brass cups built into the walls between each of the seats. He didn’t invent them, though, so we aren’t sure who originally came up with the idea. These echea were believed to resonate and amplify spoken voices, boosting their sound for each listener like a set of personal speakers. They were arranged according to precise mathematical rules that differed depending o…
