    Good little feature activated in Austin by . I suspect we’ll see more companies use Bluetooth ‘pairing’ tap-go...

    Air travel will eventually rebound - but primarily on the consumer side. Business travel will forever be reduced by 1/3rd (at least) - the time wasted by business travel for 1 meeting will be looked at as ridiculous vs video conferencing...

    these pressure waves then float through the air and a bit goes into someone else's ear - that then passes by 3 tiny bones & into a sac of fluid - that then transmits the electrical impulses to the auditory nerve then into the brain to be decoded. Amazing...

    And how we talk is a miracle we take for granted... The brain has thought, translates to pattern of pressure waves, lungs send air out of body that vibrates vocal cords in just the right way, we move our mouth/tongue to create just the right shapes of high/low pressure...

    Turns out that how most of us think about ‘sound waves’ is often wrong - they are not ‘traverse waves’ (like they’re typically depicted) but instead ‘longitudinal waves’ (more like how earthworms move)

    You can actually also go negative on the dB scale - world record is a Microsoft quiet room at -20 dB (where you can hear the blood pumping through your own brain). MSFT uses this room to test devices - and nobody can withstand it longer than 55 mins.

    Mini-example of the force of a natural shockwave:

    The actual dB scale 'ends' at 194 dB since there is no sound louder on Earth's surface. At this point - the energy no longer moves 'through the air' and starts 'pushing the air' - creating a shockwave

    Sample dB levels: * rainfall: 50 dB; * noisy restaurant: 70 dB; * loud-ish music on speakers: 80 dB; * electric drill: 95 dB; * football game: 115 dB; * thunder: 120 dB * Saturn V: 135 dB * shotgun: 140 dB * Hiroshima/Nagasaki bombs: 200 dB * 1883 Krakatoa volcano: 310 dB

    Side note - ‘The Scream’ was inspired by the event - the painter, Edvard Munch, painted it after seeing the Krakatoa-caused red skies all over the Western Hemisphere a year after the eruption.

    To put it into scale - the sound wave annihilated the island, the killed 36k people, cracked a foot-thick concrete wall 300 miles away, rupture sailors eardrums 40 miles away and could be heard 3k miles away (basically from in NY to CA)

    A random thread on sound: The loudest sound in mankind’s history is likely the 1883 Krakatoa volcano eruption - 310 dB
