THE SOUND
OUT FRONT
T
he wave

ront curvature cannot and should not
b
e useless: in
p
ractical a
pp
lications that re
q
uire
a
curved array it is logical to have curved wave
f
ronts. In most practical applications with a curved
a
rray, i
f
the emission o
f
each single element is

at,
i
t creates energy vacuums in the polar response,

ver
y
often banalized so much that some have
gone as
f
ar as stating that vertical arra
y
s

stems
can generate cylindrical wave fronts, with great
p
rot in terms of sound propagation. We now
n
eed to state clearl

that a sound source o

dimensions, such as an array, cannot generate a
c
y
lindrical wave front, except for a ver
y
limited

requenc
y
range. Furthermore, a h
y
pothetical
p
erfectly cylindrical emission from each module
of the arra
y
is to be desired onl
y
when the arra
y
is
m
ounted per
f

.
If we were to analyse the emission according
to the vertical axis of a perfectl

we would immediatel
