The sensitivity of the Minisense 100 follows a cosine law, when rotated horizontally around its axis,
or vertically around its mid-point. At 90 degrees rotation in either plane, both baseline sensitivity and
sensitivity at resonance are at a minimum. In theory, sensitivity should be zero in this condition. It is
likely that some sensitivity around the resonance frequency will still be observed – but this may be
unpredictable and is likely to be at least -16 dB with reference to the on-axis response. Note that the
sensitivity at 30 degrees rotation is -1.25 dB (87% of on-axis response), at 60 degrees, it falls to -6
dB (50%).
The plots below show the change in sensitivity observed for either:
1) Rotation about major axis of sensing element, or
2) Rotation about mid-point of sensing element.
