Search Results for ‘reflections’

Hi all, So I recently moved my system into a new/bigger room, and am in the process of treating it to improve the sound (2 channel music specifically). Basically, at high volumes the Polk A7s make my ears bleed -- these are fairly detailed monitors, but shouldn't be that bad at reference...

Hey there - very new REW user. Took my first measurements ever last night. :whistling: My question: how would you use REW to identify & measure primary reflections in mid- and high- range? My understanding (from elsewhere) is that reflections in the mids and highs are the main culprit in...

I have some early reflections coming from the floor at ~2ms and ceiling at ~5 and 8ms. The IR graph below is from my center channel which is on a stand under a large projection screen that's fairly close to the floor. I realize speaker placement is sub-optimal. At what point do early...

Now that we have been through two rounds of speaker evaluations at Sonnie's, much of my very old experience with stereo speakers and systems is coming back to me. While the products have improved dramatically over the past couple of decades, several things still remain true. First and foremost...

Hi folks! I've been over at the REW forum for a week or so getting a somewhat accurate reading of my room, and now I'd like to talk to you about how to improve the sound. I have a rectangular room ALL IN WOOD except for the ceiling which is plaster. 6.91m x 4.94m x 3.5m ceiling. Here is a pic...

Hello reading various sources (http://www.hifizine.com/2011/12/listening-room-reflections-and-the-energy-time-curve/), I understand that the ETC plot with these peaks shows the existence of strong reflections.. 1) Is this a correct conclusion? 2) Are there any means to treat these...

Hey there! I'd like to start off by saying that I'm a bit relieved already even before I post my questions. This forum seems to be a bit easier on the brain when it comes to suggesting room treatment specifically. I'm not going to mention names but other users on other forums are WAY to...

Here's a helpful beginner article from Geoffrey Morrison on dealing with annoying screen reflections on your TV: http://howto.cnet.com/8301-11310_39-20097604-285/how-to-rid-your-hdtv-of-reflections/?tag=mncol .

Hello, first post... Have been working with REW all day and have made a lot of progress. I am starting with a 12' by 12' by 8' cinder block room, so I have a lot of work cut out for me. 8 massive super chunks in the corners has helped the low end a lot. Questions 1. I have a 25dB dip at a...

Hi there ! I've made some measurement today. I just want to see the effect of the first reflections on my desk. So I mesure on axis at 1 meter the response with REW with and without some foam on my desk (I have only 2 pieces of 25cm² polyeurethan foam 2cm thick...). Here the result where we...

I had the opportunity to see several plasma tvs. Panasonic V10 and G10 and a Samsung 550. The lights from the ceiling of the store could be seen on the screens, however on the Panasonic screens, each light appeared double, or each light had another one in the back of it. According to the sales...

I am planing on building some broadband traps for first reflections and wondering if they should be open on the sides or if it would be ok to enclose the sides with pieces of moulding. I read somewhere that they are more efficient if the sides of the panel are not enclosed but I have not been...

I wondered if it is still necessary or desirable to Toe in the left and right speakers if your first reflections have sufficient absorption

Hi there, I recently bought acoustic treatment from GIK (4 tri-traps and 3 244 panels) and the differences the tri-traps made was night and day in the low-end. However putting two 244 panels behind my main speakers made them sound much, much better. Everything I put on the system, whether it's...

Greetings All, This may be off topic but it seemed as good a place to start as any ... In a building that is very lively, is there anyway of identifying where the echoes are coming from? Is there a device that can be pointed at a surface and used to estimate how much of the sound is coming...

We all know that too much sound reflection destroys the sound image. While getting rid of ALL reflections (like in a anechoic chamber) will makes the room sound 'dead'. Obviously we need SOME sound reflections in our room in order to achieve the optimal sound experience. What would be the...

Well, I created a thread here a while ago about general acoustics, and I'm still working out ideas for treatments. As many of us do, I have a number of other "projects" that are keeping me busy at the moment. Anyway, frequently, while listening to 2-channel music, I'm bothered by a tendency in...
