Sound
In Live Event Production
As the
"stuff" of our profession, Sound is an enormous topic on its
own. Although there are plans to add to it in the future, at the time of
writing this section only addresses:
|
|
The fundamental requirements of sound systems: what is
the PA system trying to achieve (what should it be designed to do)? |
|
|
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 sound systems). It enables us to
convert diverse
units of measurement into a single common currency.
Every piece of equipment in a sound 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. |

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? |
|
|
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.
