SOUND PATTERN
This shows the area of maximum sound level.
The sound extends 360 degrees around the axis of the speaker array.
It gives good sound isolation side-to-side, with very little directionality vertically.
A child in a wheelchair or a pro basketball player will be in the pattern vertically.
It is almost never necessary to “tip” the arrays up or down, there is no directionality up or down.
It is not meant to represent all of the sound emitted from the array
. There will be sound outside of the indicated area, but it will be
at a lower level than the sound in the focal area. It is important to note that our ears are logarithmic. In order to achieve a ¾ reduction
in apparent loudness, the sound energy has to be reduced approximately 99%. In quiet areas with reflective surfaces, this can be difficult to achieve.
If you have any questions, please read our white papers that explain this in more detail.
MA-4 OR MA-5
WHICH IS BETTER FOR MY APPLICATION?
MA-4 MA-5
The MA-4 was originally designed for science
museums to have good intelligibility in a noisy
environment. It is smaller than the MA-5.
The low frequency response is limited, it is
designed for voice, not optimal for music.
They come in various lengths, the lengths are
for looks, to match a screen or kisok dimensions.
All the lengths have the same pattern
The MA-5 was originally designed for digital
Signage as in malls, for voice and for incidental
music. The frequency response is tailored for
good voice intelligibility with acceptable low
frequency response.
They come in various lengths, the lengths are
for looks, to match a screen or kiosk dimensions.
All the lengths have the same pattern.
THIS SHOWS THE
AREA OF MAXIMUM
SOUND LEVEL.
IT IS NOT MEANT TO
REPRESENTALL OF THE
SOUND EMITTED BY THE
ARRAY.
