Speech Intelligibility: Gathering Additional Pieces Of The Puzzle

ProSoundWeb: 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.

This article does a really great job of outlining the dangers of ego in the technician's world. Brown thought he knew everything he needed to know about sound system design and set up because he knew how to set up a system for musical output. Many people get stuck in the egotistical trap of "Well, I do not know the solution to my problem, so the solution does not exist." While for some, the solution may take up too many resources (time, money, people, etc. see Kevin, I pay attention in class) to be feasible, often the solution exists and all it takes is the initiative to find it. Brown's research into speech intelligibility greatly enhanced his knowledge and therefore his usefulness as a sound systems designer and technician.

Even within the realm of purely music oriented sound systems, like the article said, the quality of the sound produced is always judged subjectively. The term "warmth", when applied to music can have so many meaning and possible fixes that the person evaluating the sound may not know what they want. It is up to the system designer to use their knowledge of sound and the physics of sound responsibly to find a solution to problems that arise, and not just say, "Well I think the system sounds fine, so the person giving me critique must be wrong."
