Modern control rooms are often carefully planned with appropriate
3-D CAD software. Today this includes the simulation of room modes
and the absorption behaviour of the acoustic treatments.
Modern software solutions can give you a calculation of the resulting
sound field and even make the room audible via headphones. The
best known software currently is EASE® by Acoustic Design Ahnert
Berlin. To ”know” the directivity behaviour of the speaker under con-
sideration the program needs to measure responses in all possible
directions, and it needs these measurements for many different fre-
quencies, as the directivity varies greatly with frequency.
These numerous measurements are combined in a so called bal-
loon, that show the directivity in all directions at one distinctive
frequency. We present the S1X here at four different frequencies
while the complete set of measurement holds 240 balloons. An
acoustician can implement all the measurements into the soft-
ware to preview the final frequency responses and the resultiing
sweet spot area.
ADAM offers EASE® balloons for the monitors of the SX-Series
