Frequency Response: What’s normal in an untreated room? (measurements) - AcousticsInsider.com

Have you ever looked at the frequency response of your room and thought:

Is this really what my room sounds like?

Is it really THAT bad?

It’s so easy to get worried that there might be a serious problem that you don’t know anything about.

How is there any way to trust what you’re hearing if this is what your speakers sound like!

In this video I want to go through a few examples of what a typical frequency response looks like in a small, untreated room.

I'll show you what you need to be aware of to understand what you’re looking at, the two main things to watch out for, and what to ignore.

And I want to give you a simple trick you can use to figure out what it is you are actually hearing.

This channel needs more recognition. No audio voodoo what so ever, only genuine info based on empirical scientific measurements. Superb stuff.

[rockedje]

Would be nice to show measurements before and after treatment! I love your videos by the way👍

Man! the narrow dip thing and the psychoacoustic measurement saved my life, I was becoming insane with the 59hz that didn´t change (or sound any different) even applying EQ to the output of my computer, thank you!

Although I am not building a home studio, I am more into the HT. This is really an excellent explanation how to *correctly* interpret the graphs in REW! Awesome!

[zpurpz]

Have only used Rew a few times myself. Now im ready to go back and approach this room with more confidence than last time! Thanks :)

Extremely useful.This video answers some questions about my REW measurements, that mirror the examples Jesco gives here.

Thank you! In case that you have a different takes from different positions, is there a way to export an average to IR wav.format or only one measurement per channel (mono o stereo export)? Thank you.

Would you be opening to do a video on how to acoustically treat a small mixing room where there’s a slanted ceiling? I can hardly find information on this. Our room has a ceiling where the ceiling slants up from mixing desk. Our room’s dimensions are L 144” x W 74” x H 98” (front of mix position) to 120” (back of mix position, door is located here too). Thanks!

Hey - good stuff. How would you tackle the unbalanced dip between left and right speaker @12:43? E.g. DSP the low end frequency of the left seaker up a couple dbs to match the right? Thanks for the great content!

[MattSalamone]

Thanks for sharing. How about a video on reading the other graphs, such as clarity? There's not much info from REW.

Can i just use my recording mic for this test? (Neumann tlm 103) or should i get a specified one

[azevedo]

still intrigued about the big deeps on lower frequencies ? what if have a 55hz huge deep, even if narrow you ll totally lose the fundamental tone on a open A note on bass (for instance) should n t i be worried about that ? what s the solution ? changing the listening position ? (sorry about bad English)

Room modes, reflections, standing waves, comb filters?

[AGVersace]

I'm downloading the guide right now. I like how you approach the topics. Thank you for sharing the knowledge.
I need to share the room I make music in with my flatmate because she needs a space to WFH. Noise is not a problem for her. so to give both of us a little more privacy, we were thinking of building a divider in the middle of the room. Is it a good idea to build it like a massive bass trap? The room doesn't sound bad apart from standing waves at 110hz. The goal would be taming the standing wave and the decay of the room. My side would get more acoustic treatment of course.
Should I make so particular calculation for placing the divider to achieve such goals or can I build it exactly in the middle of the room?

After following your instructions. I got much better result with my audiophile system. My Rew measurement for my untreated L-shape room is too good to be true. Only +-2db fron 80Hz to 20khz and i got strange upward trend line for SPL curve😅 is this normal or definitely something wrong with my measurement? I measured 3 times with same result. I follow instructions on rew website, measured both my L+R channels. Tools i used: Icon upod pro soundcard, Mic isk at 100 (these tools are popular in my country)

[zeroice]

How does the volume of the sound affect this chart? Will the peaks or dips change depending on the volume/output of the sound source?

[superjoseco]

is there any software (plugin) that would help me get a decent mix, without external treatment if my room sucks. For example EX mix 2 from toontrak, or any other one. Please, if you would be so kind to answer this to me, would be very much appreciated.

[ziyuchow]

You can add some example pictures or small videos to the video screen, which is easier to understand

[miguelbarrio]

Do you happen to know if a similar psychoacoustic averaging exists in Fuzzmeasure? Thx.

[周泽均]

what kind of measure mic do you use, any recommendations?
