BYU on Instagram: "BYU Physics and Astronomy students using sound to blow out birthday candles on a BYU 150 cake??? “To blow out each candle, we generated 180 decibels of sound at each candle location. For reference, a rock concert is about 120 decibels. So, this is about a thousand times louder than a rock concert at each of those candle locations.”"

sosolomon22 on Instagram: "Observed the holes in the walls and ceilings of some halls and spaces uniformly spread and specifically placed across large surfaces? The holes in acoustic wall panels are for sound absorption. They trap sound waves, and the sound energy is converted into heat as it passes through the holes into an absorbent material like fiberglass or mineral wool behind the panel. This process helps reduce echo and reverberation in a room, leading to better sound quality. #acousticsr
