A parabolic microphone is a microphone that uses a parabolic reflector to collect and focus sound waves onto a transducer, in much the same way that a parabolic antenna (e.g. satellite dish) does with radio waves. Though they lack high fidelity, parabolic microphones have great sensitivity to sounds coming from one direction, along the axis of ...
The pipe which held the "collector head" (microphone) can be seen in front of the structure. An acoustic mirror is a passive device used to reflect and focus (concentrate) sound waves. Parabolic acoustic mirrors are widely used in parabolic microphones to pick up sound from great distances, employed in surveillance and reporting of outdoor ...
A parabolic (or paraboloid or paraboloidal) reflector (or dish or mirror) is a reflective surface used to collect or project energy such as light, sound, or radio waves. Its shape is part of a circular paraboloid, that is, the surface generated by a parabola revolving around its axis. The parabolic reflector transforms an incoming plane wave ...
The microphone would face the reflector surface and sound captured by the reflector would bounce towards the microphone. A parabolic microphone uses a parabolic reflector to collect and focus sound waves onto a microphone receiver, in much the same way that a parabolic antenna (e.g. satellite dish) does with radio waves.
A parabolic loudspeaker can be used to test the sound-damping characteristics of materials used for soundproofing. A parabolic loudspeaker is aimed at the material under test, and a parabolic microphone is used to pick up the sound detected on the other side of the material. The difference between the emitted sound and the picked up sound is ...
