I am sure you've all seen John's video series on dealing with his rooms, but these (there are 2 or 3?) are exactly what @erik_squires has been helping me with.
In-Room responce measurement with Legacy Focus SE speakers
Evening all,
Odd request or question for folks with Legacy Focus SE speakers. I am doing some VERY casual speaker tests and room response measurements of dads big system. I have Legacy's smaller Studio HD bookshelf speakers, and have a VERY small space and I think they are incredible. In hearing my dad's much larger room/speakers/system (his listening room is literally the size of my tiny home!) with his larger Legacy Focus SE speakers.....I am honestly a bit underwhelmed, especially considering I have the 1/8th size Studios, and in my room/system they sound incredible.
In my home, the Studio bookshelf speakers sound 'mostly' full, warm, very taunt and articulate, and there is the right match of the tone of most all instruments and it's "weight". Like the pluck or strum of a guitar that is percussive, actually has a bit of an impact on your body. However, my dads system lacks this 'impact' or body and weight. Listening at 70-75decibell level is actually grating and feels like your head is being a bit compressed, but it doesn't "sound loud". My dad mentioned he usually doesn't play anywhere above 60ish decibels because of this issue.
Attached (I hope) is a screen shot of REW in room measurement of my system with the Studio HD bookshelf speakers for reference to what I am hearing. In my fathers system, there is a pronounced 100-130hz peak/hump and things sort of trail off rapidly in BOTH higher and lower frequencies. I'm trying to get a similar measurement to illustrate, but thought I would try to get some thoughts first.
Thanks for time!!

OP:
Don’t go buying OmniMic because I use it. REW had similar capabilities, you just have to check the settings when you do a sinusoidal sweep. There’s usually some parameter that say "stop listening after x milliseconds" I’m just not familiar enough with REW. That’s the gating limit. There’s possibly/probably also a way to blend the gated measurements with the ungated for bass. That’s something OmniMic just does out of the box but I’m pretty sure REW has something similar. Alternatively, if you ARE using REW with the gating turned on, it will cut the bass response off. |
I did mention that the frequency response measurements would not help you in this case. 😀 This has to do with hour our ear/brain integrates signal volume over time. That is, the perception of bass, mid, treble levels is an average over time as opposed to an instantaneous measure. With very live rooms like yours we perceive mid/treble as much louder because it’s staying with us longer. The total energy is Direct Sound + Sound from up to 0.6 seconds ago = 1.4x amount of perceived sound (as an example). Our ear/brain mechanism is exposed to a lot more of that energy during a listening session. As we move to cut the reflection times out the total energy there gets cut, and now we hear bass. But oh man do some people have a really difficult time with this concept. 🤣 Also worth noting that studies have shown that having meetings in highly reflective rooms is literally exhausting. Your brain has to spend so much time listening through the reverb that it tires itself out making it harder to concentrate by the end of a lecture or meeting. If you’ve ever gone home after a long meeting feeling totally drained you probably had this to blame. This is why colleges repeatedly invest in sound absorption in lecture halls. |
@erik_squires I the Earthworks Mic. It is not USB, but it does not require a calibration curve because it is dead flat and smoothly omnidirectional. |
@erik_squires "Also worth noting that studies have shown that having meetings in highly reflective rooms is literally exhausting." Yup, I think we have all experienced that first hand in bars and restaurants, and theaters. That's why when my father said "I don't like listening to music above "X" setting----I don't need to listen loud---it's just too aggravating", but I thought 'man I can barely really hear it, and for sure can't FEEL music?!!?', then checked on the DB meter and it was at 64+ DB, I knew it was the room acoustics.
