[QUOTE="Ivan Beaver, post: 72863, member: 30"] Re: The Future of Acoustic modeling The Danley 3D model is NOT an acoustics model. I guess you need to determine exactly what you mean by "acoustic modeling". To me it means building a room (down to every 6" or less if possible) and then looking at reverb time-reflections and so forth. Now if you are talking about a simple coverage map (which the Danley 3D provides), then that is a different story. One thing you HAVE to be careful of when looking at a 2D model-is the fact that it is NOT providing anywhere near an accurate coverage map. It ONLY provides a "coverage" in the plane of the loudspeakers. So it you have loudspeakers mounted in the air and pointed down-,the you will not see what the coverage is on the floor-but rather what the SPL is as you "look through" the sound field. This is often VERY different than what the coverage is on the floor. 3D is a lot more involved than 2D. 2D has its advantages, but as usual-it all depends on what you are looking for in a model. You FIRST have to determine what kind of answer you are looking for-THEN choose the proper tool to help you. It is like choosing a screw driver. FIRST you have to determine what KIND of screwdriver you need-THEN look at the other options. You could have the best phillips driver out there-but it is worthless if your screw has a slot head.. Unless you are good at grinding. So yes- using a 2D model-and a good bit of knowledge/experience and different views, you can kinda get an idea of that the coverage is in a real 3D world. But this is NOT for the average user. As with any model, you HAVE to understand exactly what the model is telling you-or you will make WRONG assumptions. [/QUOTE]
