The Physics of Parabolic Microphones: Frequency Dependence of Gain

October 13, 2023

Introduction Parabolic microphones are known for their extreme sensitivity, and the origin of their acuity isn’t difficult to guess. It is the most obvious thing about them, which can also make them a liability for field use, namely, their considerable size. Just as a large amount of weak light is captured by a telescope’s parabolic … More The Physics of Parabolic Microphones: Frequency Dependence of Gain

I Went Parabolic and Now There is No Going Back

July 17, 2023

Edit: I recently added an article on the physics of parabolic microphone gain: LINK. When I was twelve I discovered astronomy and made my first optics purchase, a cheap, awful refracting telescope made by the K-mart subsidiary Focal. I knew I needed a more serious instrument, and soon became obsessed with something called the Dynascope … More I Went Parabolic and Now There is No Going Back
