Would you like to see sound? There’s a way. This isn’t like true, complete visualization or an technological form of echolocation. Acoustic cameras locate and visualize sound itself. It can useful in application like determining sound leakage, manufacturing, and ensuring that your soundproof recording space is, in fact, soundproof. More from Bobby Owsinski’s Blog:
You might have never heard of the term “Acoustic Camera” or even connected the two words together before, but it really is a useful tool now employed in a variety of applications all over the world. It’s an imaging device used to pinpoint where sounds are coming from, and consists a microphone array along with a normal optical video camera and special processing to capture sound in a way that we normally don’t think about.
…most acoustic camera’s use 24 to 64 microphones in a circular array with a small optical video camera in the middle. If you check out the videos below you’ll see that you can immediately see any hotspots for frequency or level that lets you exactly pinpoint where a sound is being generated.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
