Like, is there any info on the FTB rooms? |

Or just some practical examples of real rooms with energy time curves and the means used to achieve the responses seen? Have found decent base level information, but not much practical examples. It's been a while since the papers I've read was written and the world may have moved on to new territories since then. Or perhaps this is basically it, and the rest is up to hands on experience and clever imagination? |

Am planning to replace some of the rear wall diffusers and reflectors with 1D diffusers made of wood. The current 2D diffusers are plastic not so fantastic. |

This will send more energy back and concentrate the return to the horisontal plane, hopefully letting me get rid of the currently specularly dominated Haas trigger/ISD termination. The level of the rear wall return isn't loud enough without those reflectors, as seen in the first ETC graph above. The specular Haas trigger is doing miracles to the perception of the room! It's really amazing how much clearer and more enjoyable everything sounds now. Though I'm sure a diffuse ISD termination will be better! |

Does the overall level of the verb looks good? Do you wizards see a graph like that and think "way too short 'verb" or "way too much!" or..? Perhaps you see something else that's worth pointing out? Any critique is welcome! It's a modest DIY effort with limited funds, though I do of course strive to make it the best room possible. The treatment is entirely modular and it's fairly easy to move things around and try different setups. |

Only in my computer and Silvia's (the other engineer working with me). Lately Silvia has been slowly compiling all our data about FTB, but I don't see us having the time to write a book/article about it honestly... And it would feel a bit pretentious too. |

But you're most welcome to drop by and have a coffee (or two!). I'll be happy to discuss whatever general questions you have about it. |

So there is a big need at one point to put things in perspective again and cut the crap.[/rant off] |

ETC, ISD, Waterfalls... Sure they're important. But what makes a great room? I can tell you: 'flat' rooms are boring. If you can get a room to be within 10/12 dB you're there - and it's already hell difficult to get there (you wouldn't believe the damage a console or workstation desk does for example). The closer you get to *perfection* the more, in my experience, they become dull and lifeless. |

Maybe there is something about the way the hearing process functions that we are overlooking? |
Thomas Jouanjean wrote on Fri, 09 July 2010 17:00 |
One question I asked myself when I started was this: how do the speakers "see the room" and how does the engineer "perceives" it? How do we react to different types of environments / How does the listening environment influences our perception of sound? Here's your pointer. |

Stick to the 2D ones if you can. |

I don't know of any wizards here. I know a couple engineers. There are no sacrifices of chicken or related animals in the design process |

It's more the pictures than the graphs that got me thinking about your overall geometry + ceiling. Did you work on one and if so, to achieve what goals? |
