Directional Characteristics
The directional characteristics of FT3432 is a measure of its dif-
fering sensitivity for sound waves arriving from various angles.
Since the electret condenser microphone used in the FT3432
is a pressure-sensitive type, it should be equally sensitive in
all directions. However, refraction and cavity effects cause a
certain microphone directional response at high frequencies.
