Sound In Live Event Production
As the "stuff" of our profession, Sound is an enormous topic on its own. Although we plan to add to this section in the future, at the time of writing it only addresses:
PA System Design |
The fundamental requirements of sound systems: what is the PA System trying to achieve (what should it be designed to do)? |
The Decibel |
The Decibel is a basic mathematical tool for comparing sound levels (either in the form of sound pressure, or in other units of measurement commonly used in PA systems). It enables us to convert diverse units of measurement into a single common currency. Every piece of equipment in a PA system has an effect on signal level (either overall, or at a particular range of frequencies). The decibel is used to describe what is happening to signal level, irrespective of the unit of measurement. |
Loudness |
Everybody has heard something that was "too loud", or struggled to hear something that wasn't loud enough. What is loudness? How should a sound system affect it? |
The Law |
What does the law have to say about sound? |
If you wait long enough, this page may itself have more to say about sound: what it is made of (how air and ears combine to produce our experience of it), and how its physical properties make some enclosed spaces (rooms, speaker cabinets) work better than others for PA systems.
