What does the frequency response of such a mastering room look like?
Hmm - simple question, long answere:

So far we have only done the measuring and during that we checked some of the resulting graphs on the laptop. WSDG will now carefully evaluate the data and then we will see (when we receive the final documentation) if we missed anything... BUT, so far what we have seen and heared looks and sounds exceptionally good.

This may not be scientifically correct, but to me it seems there are two types of frequency responses that matter - one is regarding the room itself, which we averaged (=different positions of the omnidirectional speaker each with 2-3 meaurement mic positions and 4 measurements on each mic position). This is what was done for RT 60 measurements. Of course they also made sure no single measurement was out of whack...

The other is the specific frequency response of the monitoring system in it's final position (since we are using free field speakers) with the main focus on the measurements at the listening position (single measurements, not averaged).
For our mastering room this means: monitors go down to 16Hz! Some minor dips and peaks in the bass (very controlled and much less than a typical control room according to WSDG) and a VERY smooth mid and highrange - no visible (in the impulse or frequency response) or audible early reflections, no resulting combfiltering. To put in words: Deep and focused Bass and a great soundstage (wide, detailed - strong phantom center) - A GREAT SOUNDING ROOM!!

The graphs themselves don't look entirely different than what you might find in a manufacturers spec sheet, but they usually don't say much about how it sounds anyways. There are rooms and speakers that measure flat and still sound like sh*t...

Also - these rooms are really quiet. No computers, hardrives or anything with a fan or noisy in any other way are inside the room. Isolation is great, therefore no noise will ever mask the sound comming from the speakers which helps the sound quite a bit... We measured Noise Criteria (NC) with a VERY low self noise 1/2" measurement mic (since 1/4" measurement mics have too much self noise for this kind of measurements), but the self noise of the mic was still too high to measure NC... We were still only measuring the self noise of the 1/2" measurment mic.
