38% rule - I always skip the first 38% of youtube vids because that's where the real content starts.

It really is a bit annoying how long these videos are. There is good information, but goodness let's get it out a little quicker. When I do finish a video, I'm always asking myself what took so long to get to the point and feel a bit confused. I appreciate the channel. Just my input.

nice one. after going down the rabbithole of fixing bass problems i decided to just put my table back where the room sounds best. so i inadvertently used some of your bass hunter technique, and i can recommend it!

Find a song with a good amount of sub bass. Bring it to your daw, find the tempo, loop 2 bars where the bass is good, move around the room….

Would a listening test like this work better by playing some sustained synth notes, like a basic sine wave, at various low end frequencies, say E0 (20.6Hz) through E2 (82.4Hz)? Might be easier to detect changes as you move around when there is a constant level, same frequency, sound emitting.

On the first diagram, you actually pointed to 7.5 feet of the length of the room, which is 31%. 38% is at 9.12 feet (9 feet 1.44 inches). I'm guessing the 7.5 feet is better? The 38% mark or a little past 9 feet is close to the 4th standing wave (yellow) null. Unless the 4th axial mode doesn't matter much? If that's the case, then the 38% position is fine? (in the 2nd diagram, the person is sitting very close to the 38% position). There's only 3 axial modes showing in the 2nd diagram. Added: Oh I see using the Bass-Hunter technique, that is probably just the best way to find the listening spot.

Very interesting how the axial mode is skewed across it's length, due to the delta between the front and back wall boundry density. Great video 👍

@@chinmeysway Yeah maybe one of those things you don't really notice. My current setup has a door in the front right corner and the left is solid wall/plaster. Still sounds fine and imaging is good. I listen at very low volumes anyway so I don't excite the room too much.

Does my room sweet spot change when I change speakers? Like if I do the bass hunter method with the monitors I got now and then switch to a different one do I need to do it all over again?

Do you assume that the speakers are positioned at the wall or slightly off (roughly 30cm 40 cm)

I always put the speakers at the mid point of the length of the room and both speakers touching the side walls. Based on measurements, this seems to excite less modes. And based on listening test, this placements always has wide soundstage with good clarity.

What’s your take on active bass traps like the PSI Avaaa or using a quad subwoofer array, where you have 2 stereo subs on the front wall playing in phase and two on the back wall playing 180 degrees out of phase to cancel out room modes and eliminate humps and null spots?

It's a thing. Pairs of subs in the correct place essentially interact with the room modes with inverse polarity, so can cancel out certain room modes.@@chinmeysway

To use his bass hunter technique. You must find the sweet spot with the room empty and that becomes your listening position. You then place your speakers in respect of that seating position.

so why not 38 % from the side wall as wel l- ? on the same logic - looking at your diagaram the mid point looks problematic

Finding the best position by ear is nonsense as you do not have a proper reference just the sound you used to listen which could be completely off, so take several measurements is muuuch better way how to do that..
@zerobject
@zerobject Жыл бұрын
Maybe it's best to combine measurements with listening impressions then. At least this is what Jesco showed us in his earlier videos.
@KaneDWilliams
@KaneDWilliams Жыл бұрын
He is saying to take multiple listening tests, with various pieces of music. If measurements was easier, he’d say to do that as he also takes measurements whilst adding treatments. Remember, this is only about listening for a balanced low end, not the entire frequency range.

The 33 and 38 percent rules are not universal to all rooms. In a room that is 30 feet long, at 38% the Listening Position would be 11 and a half feet from the front wall and your studio monitors would be 7 and a half feet from the front wall. It would be ridiculous to have your studio monitors and your Listening Position that far away from the front wall! No studio would ever do that. In contrast, if you had a room that was only 7 feet long, at 38% your desk and studio monitors would be crashing into the front wall! In a room that's only 7 feet long, your only option is a Listening position at 45.8%. If you map all of these things in a CAD program you can clearly see that 33 and 38 percent ONLY work for rooms within a specific length range. And to be technical... the midpoint distance between nulls is not 33% it's actually 32.8% and 38% is actually 39.6%. Most smaller room lengths will have a Listening Position at 45.8%.
