Skywatchers have been fascinated by 'meteors' radiant glow for years. Early reports show that the sounds of these luminous meteors have been recorded, a rare occurrence due to 'sound's slower speed compared to light. Astronomers studying meteors suggest that ionized tails can produce electromagnetic waves and their investigations show it is in ELF and VLF bands, causing nearby metal objects to vibrate and create audible sounds, known as the Electrophonic effect. These waves travel at the speed of light, confirmed by various measurements. This study details the detection of such signals during the 2017 Geminids meteor shower using a loop antenna and SuperSID monitor, distinguishing signals from local and natural noise. Factors affecting data recording are also discussed. These findings shed light on an overlooked aspect of meteor observations, guiding future research in this field.
