Room Nodes

[pittsburgh]

I just finished a wiring project and got asked to make the room that I wired sound better. There are some definite room nodes between 320-360Hz. The owner of the studio wants to address the issues of the room, I'm sure there are more than the nodes, without significantly decreasing the decay time of the room.

Where do I start? I guess it would be nice to be able to see frequency response for the room. What kind of test equipment/DAW plug-in stuff do I need?

Thanks for the help,

There is an announcement at the top of the forum about what to do to assure getting as many responses as possible.
The announcement leads to this post (click here). Actually, several people, who are experts on this forum, will most likely not reply if you don't do what is written in that post. Many others who are very helpful, will most likely not reply out of respect for the moderators' wishes.

Regarding room analysis, you need a good analysis mic (eg Behringer ECM8000), a good pre-amp with flat response, a good audio interface for your computer, and a program called REW (Room EQ Wizard). REW will pretty much do the entire analysis for you (once you learn how to use it), and show you graphically everything that is wrong with it.

If you post the REW graphs here on the forum, along with detailed accurate diagrams of the room, and some photos, then folks here can probably offer suggestions of how to fix it.

Thanks for the info. I got referred here from someone at PDIY.

please update your profile to include your location. if the problem frequencies are that high - using some slat resonators or perforated metal absorbers should be able to target that as broadband and preserve the HF component.
