What do the settings on the equalizer mean?

Answer 1

Sound travels and reaches your ears in the form of waves that distort the air. You hear the sound when the waves reach your ears and cause your eardrums to vibrate. It is the frequency of this vibration that determines whether you hear the sound as a "high" sound (e.g., "treble") or "low" sound (e.g., "bass"). Every equalizer divides an audible sound source into separate wavelengths, or "bands" of audible sound, so that you can adjust individual bands to improve the overall sound of whatever source you're listening/applying the equalizer to. Consider the "bass" and "treble" adjusters on the typical auto or home stereo as a very simple equalizer. When you turn up the "bass," you are maximizing a broad range of the lower frequencies in your sound source. When you turn up the "treble," you are maximizing a broad range of the higher frequencies in your sound source. The more individual bands you have on your equalizer (they come in many different sizes and configurations), the smaller portion of the audible spectrum of sound each individual band controls, and the greater level of detailed control you have over the entire spectrum of audible sound going through the equalizer.
