2. Parabolic microphone - Wikipedia

   en.wikipedia.org/wiki/Parabolic_microphone

   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 ...

3. Acoustic mirror - Wikipedia

   en.wikipedia.org/wiki/Acoustic_mirror

   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 sporting events. Pairs of large parabolic acoustic mirrors which function as "whisper galleries ...

4. Microphone - Wikipedia

   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.

   sounds from all directions, whereas uni-directional microphones are sensitive to sounds from directly in front of the microphone. The latter include cardioid, supercardioid, and hypercardioid microphones. Specialty microphones are also mentioned: the parabolic reflector, lavalier, machine gun, tie-clip, zoom, and pressure zone microphones.

   eric.ed.gov/?id=ED328209

   This paper describes the types of microphones that are available for use in media production. Definitions of 16 words and phrases used to describe microphones are followed by detailed descriptions of the two kinds of microphones as classified by mode of operation, i.e., velocity, or ribbon microphones, and pressure operated microphones, which include crystal, moving coil, carbon granule, and ...

7. Parabolic loudspeaker - Wikipedia

   en.wikipedia.org/wiki/Parabolic_loudspeaker

   Parabolic loudspeaker. A parabolic loudspeaker is a loudspeaker which seeks to focus its sound in coherent plane waves either by reflecting sound output from a speaker driver to a parabolic reflector aimed at the target audience, or by arraying drivers on a parabolic surface. The resulting beam of sound travels farther, with less dissipation in ...
