  • “Sudden” doesn’t matter. “Loud” does.

    I don’t see how anything non-Newtonian would be better against sudden sounds. In fact it would be worse, as they’d get more solid and thereby transmit MORE of the noise you’re trying to block out. Or maybe they only get more rigid but their sound transmission properties don’t change at all. Either way, sounds somewhat pointless.

    The only way I can think that something like this would work would be to have a molded vacuum chamber as an ear plug, with a specifically engineered sound transmission bridge inside. With too much energy trying to go through, it would break. But I doubt it would be quick enough to be effective, and they’d also be one time use, and extremely fragile.









  • In a city with no prominent industry, people will always needs healthcare, childcare, food, and maintenance on their belongings.

    Healthcare: doctor, nurse practitioner, nurse, dentist, dental hygienist. Skin and hair care might be stretching the category, but everyone needs haircuts.

    Childcare: teacher, ECE, nanny. Big spectrum here from no training required to professionally registered.

    Food: production, supply, distribution, and sales. So farmer (but that’s capital intensive), food maker (baker, chef, cook, butcher) or distributor or seller.

    Maintenance: vehicles (tires, oil changes, body shop, parts, detailing), homes (carpenter, painter, gas tech, electrician, window installer, roofer, landscaper), appliances (appliance technician), power equipment (mechanic, blade sharpening).

    Probably more, but that should be a pretty decent list to start with, and all should be pretty portable no matter where you go, save for certain licenses that may be specific to a state or province.
