KLOVER MiK Parabolic Microphones at EAA Airshow

Custom KLOVER MiK 26 parabolic microphone at EAA airshow (960x720)

One would normally think that recording audio of airplanes at an airshow would be an easy task.  The planes are very loud and you are out in a wide open space.  It should be easy.

These past two summers, we have worked with Steve Oakley, an audio engineer working with the video department of the Experimental Aircraft Association, to capture clear audio during the AirVenture airshow in Oshkosh, WI.  We developed a dual layer version of our KLOVER MiK 26 (26-inch) parabolic microphone to isolate the microphone from the PA system located behind it.

Steve has posted a video describing his experience with the custom parabolic mic.  The audio makes it clear how well the dual layer parabolic isolated the aircraft from the PA system.

While at the airshow, we also tested our small, KLOVER MiK 09 (9-inch) parabolic mic.  The primary question was if the small unit could capture the low-frequency sounds of the war planes.  It proved to be very effective at the low frequencies.  We analyzed the video and found the captured audio goes down to 40 Hertz.

Wireless Lapel Mic vs. Small Parabolic Mic

Why would you use a small parabolic mic instead of a wireless lapel mic?
When faced with the task of recording an interview, most people will turn to a lapel (lavaliere) microphone for capturing the audio. The small microphones are seen every day on television, and they are often used without our seeing them.
