As an instructional aid, and / or for professional use, I
propose to mount LED(s) on microphones and/or
loudspeakers, where the visible polar pattern of the
LED(s)
match the polar sensitivity or dispersion pattern of the
electroacoustic device.
For Instance, an omnidirectional mic would
feature a
frosted LED uniformally visible from any direction, while
a
cardioid mic would feature a directional LED matching
the
polar pattern of the mic. Similarly, figure-8 mics would
show the polar lobes from each side, but none from the
polar minima.
Loudspeakers would be similarly enhanced, and either
could be equipped with frequency-selective lighting (red
for low frequency omnidirectionality, through green,
yellow, blue, etc., matching the frequency-dependent
polar
response of the transducer.)
Powered by phantom power or AA batteries.

A scanning laser would be better. |

This sounds like a very good idea. |

Hang on a sec. Wouldn't all those LEDs block the
sound? |

As long as the LEDs are small compared to the
wavelength of the highest frequency of interest
(20kHz, ~1.7cm) there should be no significant
blocking. |
