Parabolic Microphone Dish (Customizable)

Creating a parabolic bowl shape model involves configuring the interior shape as a precise curve with a focal point exactly at the top of the defined microphone. The microphone points forward, limiting the pickup area but achieving effective sound collection. A higher total height enables building a larger parabola and placing the microphone elsewhere - just flip its orientation to face backwards. When utilizing small cylindrical microphones that reach exact specified lengths, individual adjustments are essential due to variations in device size. An android-based splitter paired with an amplification app transformed my microphone signal into amplified input via headphones for optimal listening experience. Its effectiveness was particularly evident during family gatherings: the cup's gentle placement on chests detected heartbeat signals clearly and strongly surpassed standard stethoscope capabilities.
