Room Acoustics
Everyone has heard this term, but you probably won’t deal with it in the terms of live sound until your live sound jobs get a bit bigger.
Did you know… that the room is part of the sound? Well it is.
Since all sound waves pass through the room to the listener, the room has a change to have an affect on the sound. There are many room factors that affect the sound: Size, Ceiling height, floor and wall material, and your audience (when they’re in there) all affect the acoustics of the room. The room may add bass frequencies to make it sound muddier that it really is, or add high frequency information, or all kinds of different things. CORRECT THESE PROBLEMS WITH A MASTER EQ, NOT THE THE MIXER CHANNELS. This is because you want the mix coming out of the mixer to sound the most like a professional record, or well the most un-influenced by room acoustics. This is because… well it’s kinda hard to explain… you want the main outputs of your mixer most un-influenced as possible… it’s just good practice AND if you are using the Equalizers on the channels to fix acoustics, the Equalizers are now less able to shape and fix the sound of that channel.
Room acoustics and also can lead to feedback. If you have a room that has a spike at, for example 1,000 hertz, you are more likely to experience feedback in that area. If you feel the room and the feedback are linked, reduce that frequency on the Main EQ or if it's just that channel, the channel EQ.
Be sure that your subs and tops are balanced properly (that is if they are separate). If not the sound may appear muddy and it really isn’t, your subs are just up to high making it sound muddy. This causes you to use EQ more than you have to, which makes the sound less-natural and uses up your Equalizer bands.
