What is Sound?

Before we discuss sound equipment and systems, let's take a look at sound itself. Keeping it as brief and as simple as possible, we'll explain the basics you need for a full understand of the content that follows.

Sound Systems

The part of a sound system that is most obvious to casual listeners who are not involved in the sound business is probably the speaker system that produces the sound output that we hear directly. The speaker system is actually only the last in a chain of several devices that amplify, route, and process the sound signal.The part of a sound system that is most obvious to casual listeners who are not involved in the sound business is probably the speaker system that produces the sound output that we hear directly.

Application 1: Announcements (Conveying Information)

If you go downtown you're likely to hear a variety of announcements broadcast from shops and other facilities. The sound systems that broadcast the information you're hearing have been carefully designed and installed to suit the needs of each individual facility... or at least, they should have been.

Application 2: Background Music (Enhancing the Environment)

Shopping centers, restaurants, hotels ... just about all of these and many other facilities will have a sound system for background music. Let's take a look at the role background music plays in such situations, and what is required of the sound system to deliver maximum performance.

Application 3: Live Events (Sound Design)

At live events and concerts you'll often see one or more sound engineers operating mixing gear in the midst of the audience, and perhaps technicians busily making adjustments to equipment on stage. This is probably the first image that comes up when we think of "sound professionals." It can be a very complicated business, but here are some of the basics.

The Merits of Digital Sound

Ever since the CD appeared as the first digital music medium for consumers in the early 80's, digitization of the audio world has progressed steadily. Commercial sound systems are being designed to take advantage of the numerous merits of digital technology as well. Here's a brief summary of the basics of digital audio.
