🏴‍☠️🎶 Psychologists explain that the steady beat of #sea shanties functioned as a biological metronome for sailors. The rhythmic coordination allowed groups to time their physical efforts while creating a shared experience that reduced #stress during difficult labor.

MIT News: MIT engineers’ virtual violin produces realistic sounds. “While there are software programs and plug-ins that enable users to play around with virtual violins, their sounds are typically the result of sampling and averaging over thousands of notes played by actual violins. In contrast, the new computational violin takes a physics-based approach: It produces sound based on the way […]

🌱🔈 #Tomato and #tobacco plants produce high-frequency clicks when stressed by dehydration or physical injury.

These ultrasonic #sounds reach volumes comparable to human speech but remain inaudible to people. #Research suggests that air #bubbles forming and popping within the #plant vascular system create these #acoustic signals.

🌋🔊 Scientists estimate that the 1883 #Krakatoa eruption reached 310 db at its source and produced a pressure wave that circled the globe several times. The sound was so powerful that it was heard over 4,800 km away and damaged the hearing of sailors far from the #volcano.

TIL that a seashell can form a Helmholtz resonator with low Q factor, by amplifying many frequencies, resulting in "rushing sounds of the sea FX
Helmholtz resonators are important for me in PA Audio Engineering, studio Engineering and pure Physics

Subwoofers have Helmholtz resonators. We use Helmholtz resonators to remove standing waves in acoustic ENV:

In every and all stringed instruments, response curves of instruments consists of a series of Helmholtz resonance modes in association with the size and shape of the resonance cavity including vibration damping from absorption by the resonance cavity material

Inside a Big Cat’s Roar

The roars of big cats — tigers, lions, jaguars, and leopards — carry long distances. In part, this reflects the animals’ size: large lungs exhale lots of air through a large voice-box, whose vibrations resonate in a large throat. But size alone does not make the roar. Below are examples of two big cat voice-boxes. On the left is the nonroaring snow leopard; on the right is the voice-box of a roaring jaguar. The red boxes labeled “VF” mark each cat’s vocal folds. Nonroaring cats have triangular folds, while roaring ones have thick square or rectangular vocal folds. These rectangular folds are more aerodynamically efficient, allowing them to produce a wider range of output levels. They’re also more resilient to the intense forces of a roar, thanks to the cushioning effect of fat deposits inside them. If interested, you can learn more over at Physics Today.
