The red dots represent Vertices (points) that define a Face (surface area). The green lines outline the Audience Areas on which EASE and EASE JR will map many of the acoustical simulations. They are typically placed 3.94 feet above the floor or approximately the same height as the ears of seated listeners. The red chairs are Listener Seats representing specific locations within the room. They are useful in detailed acoustic investigations.

The purple lines show the aiming points of the loudspeakers.

Note that the closed room model defines only the inside of the room, The outside of the room is of no interest to EASE and EASE JR. They are only concerned with the internal characteristics of the room.

Also note that the closed room model shown doesn’t include any windows or doors. EASE and EASE JR are only concerned with those architectural details that are acoustically significant and details, such as windows and doors, are quite often left out. Their relatively small surface areas have little significant impact upon the acoustics unless they are unusually large or there are lots of them.

Many users, however, add these details to dress up the model and enhance their client presentations. How much detail is added, if any, depends upon the user.

Constructing the room model needed for the electro-acoustic simulations is not nearly as difficult and time consuming a process as it may appear to be at first glance.

Both EASE and EASE JR include a wide array of modeling tools that speed up the procedure and turn what appear to be difficult-to-draw items, (such as columns and curved surfaces) into relatively simple tasks.

CREATE SHAPES

Create Shapes allows curved objects, such as columns and round structures, to be created by simply entering the diameter and height and then pressing a single button. Domed ceilings can be just as easily created. The model below was created in less than 3 minutes by adding a domed ceiling to a cylinder.

PROTOTYPE ROOMS

Prototypes Rooms, in many cases, offer an even simpler method. Open the prototype room that most closely resembles the room you are modeling, change the dimensions to correspond to your room and then press a button. It’s that easy.
EASE4.0 and EASE JR 4.0 both include 33 prototype rooms covering a large variety of room types.

DXF FILE IMPORT

DXF File Import can be another great time saver. It allows 3D models constructed in other 3D drawing programs, such as AutoCad, to be imported into EASE & EASE JR. If the room model already exists and it quite often does in the Architect’s files, why create it again.

OBJECTS

Objects, a new EASE and EASE JR 4.0 feature, allows a number of items to be gathered together into a single Object. The Object can then be duplicated, moved, turned, rotated, and otherwise manipulated. This makes the creation of steps, bleachers, rafters and other repetitive items a snap. Create a bleacher section once, for example, and then repeat it as often as needed.
Objects can also be saved and used again and again in other projects.
