The first set is raw and the second set is corrected for the inaccuracies of the Radio Shack SPL meter. It has two set of one-third octave test tones. I have two different SPL meters and that helped a little. The biggest problem is the unreliable SPL meters.
WHAT WEIGHTING DOES TRUERTA USE MANUAL
There are basically three types of problems when you do manual equalization: Initially, I tried to use one-third octave test tones and two SPL meters (a digital Radio Shack purchased over fifteen years ago and an American Recorder Technologies SPL meter purchased a couple of years ago) to equalize the room. Additionally, I needed something that would have a reasonable cost as I had no intention to end up in a divorce court.Īfter some search, I ended up buying the Behringer UltraGraph FBQ6200. For this reason, I decided to search for a manual equalizer that can handle the entire audible frequency range.
Additionally, bass frequencies may not be the only problems in this room as it is a relatively large room. It is not exactly the ideal room to deal with.
I recently upgraded my two-channel room with a tube pre-amp, a CD player with superb DAC, a better turntable/cartridge, and two super tower DIY speakers with 15" amplified subwoofers. Unfortunately, many SPL meters are not very reliable across all frequencies and doing the work manually is tedious and subject to error. One option is to use an SPL meter and a lot of patience. Using these manual equalizers by ear alone is not sufficient.

As a result, we see an abundant numbers of one-third per octave graphical equalizers in the pro market. Dialog intelligibility, reverberation, feedback, and other higher frequency problems become much more important.

Most of them have to deal with much larger rooms such as movie theaters, auditoriums, and indoor stadiums. Professional users have a different problem.
Because the most important problems in small home theater rooms are experienced in the lower frequencies, it is best to use equipment that can handle one-tenth to one-twenty fourth per octave equalization for frequencies below 200Hz. Additionally, some users may use manual bass equalization with equipment such as the Velodyne SMS-1 or sofware programs such as REW or TrueRTA and calibrated microphones. In the vast majority of home theater rooms, equalization and speaker level setting is handled by auto calibration programs such as Audyssey. The third solution is equalization, particularly equalization in the lower frequencies. Another solution is to use bass traps in the room. One solution is to use multiple subwoofers (two or four). At some locations, the bass will be too loud and at some locations, it will be very difficult to hear any bass. The main result of these room modes is that the bass will become uneven in the room.
