If you've spent any time looking for information about treating your space, chances are you've run across the term "early reflection point", "First Reflection Points" or "mirror point". These are just semi-technical terms used to describe a phenomenon common to all enclosed spaces no matter what size: that the direct sound from the loudspeakers will arrive at the listener's ears before the reflected sound does. It reflects not just off of the walls to the left and right, but off the floor, the ceiling and everything in-between.

I wanted to do the mirror trick but it requires a friend. 😔

Great video! It was very informative and was created in a way that is interesting and not boring. Thank you for sharing.

@GIKAcousticsLLC 12 лет назад

Thank you. We also have a article talking about early reflections that get a bit more technical.

Glenn, thank you for providing so many education resources! These videos are great

Thanks Zach. Glad you found them helpful.

Always helpful Glenn.

Yes you where ever you can see the monitor in the mirror is where the reflection point is. Let me know how it works out for you.

BRO I BEEN RESEARCHING FOR HOURS AND THIS IS ALL I NEEDED TO KNOW THANK FUCK THERES SOME PEOPLE WHO DONT OVERCOMPLICATE EVERYTHING

Hi Glenn what about the center channel in a home theater should I use an absorption material also for the first reflection point? Tnx

How to find ceiling reflection points?

@elvehornacek 7 лет назад

Great Video. What program did you use to create the room space?

@DjMojsterJaka 11 лет назад

Isnt a bass trap more effective being mounted 4 inches of the wall (if its a 4 inch bass trap)?

@fret2fret221 3 года назад

I genuinely don’t understand the mirror trick. I do this and I feel like I can see the speaker the entire time. At no point do I not see the speaker in the mirror. Someone please help me out here.

@dedskin1 8 лет назад

i would liek to hear a difference of placing the defusers behind the monitors , both PC and studio monitors , li will do the test if there is none on YT

@markparris228 10 лет назад

Great practical video. Is there an ideal listening postion within the room (distance fromm front wall - mix editing position) and (distance from rear wall for vistors listening postion).

@GIKAcousticsLLC 10 лет назад

Every room is going to be different so you would need to test the room to find the best over-all location. I will say if the room is small you might want to start with the monitors close to the wall.

@DoubleDashDiamond 3 года назад

Could someone possible confirm to me that for example if I am using the mirror trick on my left wall... do I eed to see the left speaker in the mirror or the right speaker? Thanks in advance

@PhDBarinas 9 лет назад

Does this apply for recording voice-over?

@ArrogantBaSStard 3 года назад

What if you have an asymmetrical room? The best I can describe my room is like the room in this video but the left wall is about 31 feet away.

@medadrufus 10 лет назад

Just wondering what animation software are you using?

@Lordsallakh 9 лет назад

god bless u!

@dedskin1 8 лет назад

thing is , when im behind my monitors there is nothing there , what reflection ? Only when on high levels i can hear mids and highs behind my setup , but under normal conditions , there is nothing behind the line of my monitors that are positioned the same as on the video, why use bass traps and defusers , i cant here that bass here and there are no mids and highs behind ?

@KEZOSON 11 лет назад

im having trouble understanding the mirror trick. I've been told this trick a few times and never understood it. so i sit in my mixing position in front of the computer - and i have a friend drag a mirror monitor heighth along the left and right wall. would i see the monitors from all angles of the wall?

@77936fief 10 лет назад

would this happen if you completely soundprrof the walls? if it's a perfect square room and it's soundproofed would you still have the echo?

@GIKAcousticsLLC 10 лет назад

Sound proofing is when you stop the sound from going through the walls so yes you still would have "echo". In fact, in a lot of cases when a room is soundproofed it has more reflections for a longer time (longer echos).

@77936fief 10 лет назад

so does it make more sense just to get acoustic padding for a room then?i don't want to make a studio out of the room, i want to make a music room where i can get the most out of the sound...

@GIKAcousticsLLC 10 лет назад

ernst de waal Yes would would want absorption and diffusion on the walls. If the room is small then go with mostly absorption. If you go to gikacoustics.com you can view a bunch of other videos that talk about room acoustics. Look under the education area.

@77936fief 10 лет назад

Glenn Kuras thank you so much, it's appreceated

@Agalliasis1 10 лет назад

I can't see both speakers on one wall. I can only see the left speaker on the right wall and the right speaker on the left wall. This video says that we can see both speakers on one wall if I got it right...

@ersk83 3 года назад

Start in the corner left corner behind the speaker and move it away from the front Wall. When you can see the element of the left speaker thats the first reflection point from your left speaker. Keep movin it until you see the element of your right speaker, thats the second reflection point of your right speaker. Then do the same procedure on your right Wall. If your speakers are close to the side walls the first reflection point is very close to the speaker.

HOW DID YOU CREAT THIS?

@LexBeatz 5 лет назад

He did this with this software: www.gikacoustics.com/room-acoustics-visualizer/ (if u find this extra helping PLEASE SUBSCRIBE TO MY INSTAGRAM lexbeatz1 and to this youtube chanell if u find this extra helping)..thank you!

@IllisiaAdams 4 года назад

Thank you for an informative video :-) I learned some things that I did not know before :-) (It's a shame the voiceover sounds so forced, and the audio quality isn't great)

@RealHIFIHelp 3 года назад

Hmm, interesting.

@jibjibam 3 года назад

Sound is not a laser beam to reflect off one spot. I guess it disperses, spreads, dissipates in a spheric shape starting from the source.

@gikacoustics6360 11 лет назад

Thanks Daniel.. Glad that you found it helpful.

@gikacoustics6360 11 лет назад

Sure spacing the panel from the wall is always a good thing, if you have the space for it. Our panels though have a built in air gap so you can mount them flat to the wall.
