Just what is a decibel? What does it mean to turn it to 11? If you’re dancing inside the Ministry of Sound as the six Martin Audio ground stack speakers offer the most profound experience of, say, Chemical Brother’s Let Forever Be, just how many decibels are pummeling your body? Here’s more from Ethan Hein:
The first thing to understand is that zero decibels does not mean silence. Instead, it refers to the quietest sound that humans can hear, which is roughly equivalent to the sound of a mosquito from ten feet away. All other decibel levels are multiples of this reference intensity.
The next thing to understand about decibels is that adding them means multiplying the actual sound power levels. Playing your instrument one decibel louder means that you are putting out one and a quarter times as much sound power as you were before. Playing your instrument one decibel quieter means that you are putting out about four fifths as much sound power as you were before.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
