Location, Location: Loudspeaker & Microphone Placement Basics

ProSoundWeb: Some worship music mixes are a real breeze – there’s no feedback, the instruments and vocals are well balanced, and the levels are comfortable for the congregation from front to back.

But other times, it can be an audio nightmare – the loudspeakers are belching pure feedback, the folks up front are sustaining permanent ear damage while those in back only hear only mud, the minister and/or music director are not pleased, and you’re in the hot seat.

I learned a lot from reading this article. I just entered the sound mini of Stagecraft and this article was informationally insightful as well as easy to read. I think people often forget that the smallest adjustment to equipment can make all the difference. Whether its for a performance at a church or a concert, the advice this article provides is useful for all people who do/need to know about sound. I never knew that loudspeakers should be hung to disperse high frequency sounds, or that microphones have a directional patterns. These little details that I’ve done unknowingly for some performances at CMU (I got to hang a sound arracy for A Bright Room Called Day) are basics that I might have already done, but it’s good to know it’s an actual rule of sound. I also think that placing loudspeakers in front of performers is something we do inherently at CMU and now that I know it’s an inherent rule, it makes so much more sense.

This article was incredibly informative! The author has this ability to describe what they are talking about in-depth without going over a layperson's head. Often, I believe that we as a society jump to solve all of our problems instead of addressing the root of the issue. As the author writes, though, "all of the advanced signal processors, compressors, and limiters in the world won’t help if loudspeaker placement errors lead to a system with inherent sonic errors." Often, just a bit of thought as to placement of speakers in a sound system can address many SI and other clarity issues. By ensuring even coverage of the audience, even if it takes a bit more effort, a sound designer / technician can guarantee a better solution for everyone! Some of the tips that the author suggests include elevating the speakers and ensuring they have an appropriate throw of sound for the space.
