[QUOTE="Brad Weber, post: 41208, member: 114"] Re: How do the attributes of a room affect the EQ? As Greg and others noted, you may be able to compensate with EQ for some environmental acoustics issues but you can't alter the room acoustics with equalization, the best you can do is to try to minimize the negative interactions of the system with the room. The RTA decay or ringing out the system approaches are beneficial but some system-room interactions are listener/measurement location specific, so you may want to look at more than one location. Also keep in mind that the acoustical environment, from the ambient noise level to the absorption and diffusion present to the temperature and humidity in the space, may vary as the audience varies, so you sometimes may need to initially 'guesstimate' those effects and then tweak them later on. What you might do may also be dependent on what tools you have. You can do some with an octave EQ and your ears, more with a one-third octave EQ, a RTA and your ears and even more with a parametric EQ, dual channel analyzer and your ears. [/QUOTE]
