ANC headphones are great for low-frequency (bass) sounds. But with cheap headphones I find I can still hear speech. I think new housing uses mass loaded vinyl to prevent high frequency sounds from passing through walls - perhaps heavy, 1lb or 1kg headphones with ANC are the solution for experiencing real silence in e.g. a busy workspace? Does anyone have an idea if material weight or density is a big factor in sound insulation? Along with air-tight sealing.

I don’t think this is even possible. Noise canceling works by creating reverse waves that hit your ears at the same time. You have to be able to calculate how long it will take for those waves to hit each set of ears and be able to direct sound at them.
That's the simple, signal-processing oriented way to noise cancellation. But what if the software/ai is advanced enough to reproduce a sound, but erase a certain aspect of it? Like how photo editing can edit out an object or background? Then the headphones can use a seal to completely block out all noise, and play only the sounds the user selects!
If we could make a seal that blocks out all noise small (and confortable) enough to fit around a headset, we wouldn't need the whole NC setup.
Earplugs below my bose headset work wonder to block out anything short of cataclysmic, but it's hardly practical. And I can't exactly play music with those on...

#43Does anyone here already tried ANC on these new true wireless earbuds ? Does a better better isolation always imply to a better sound quality ?
AirPods Pro certainly has much better bass with ANC on, and I'd say overall sound quality too. It also sounds louder, although I'm not sure if that's just perceptual: higher sound levels are fine to me with ANC off, but are unbearably loud with it on. That's in both loud and quiet surroundings.
I've noticed this as well. When I have ANC on in like a grocery store with music playing at a comfortable volume, then turn it off, I can barely hear the music.

Is it quiet on the outside too?
For a 3/4 ton truck, yes. Compared to a small car, no.
I’m sure most of the noise will come from the size/type of the vehicle (air displacement and styling) and tires. Truck tires are not known for being particularly quiet. The larger the tread, the worse the noise...

#45>wearing active noise canceling headphones for extended periods of time can be uncomfortable and even cause injury Does anyone know what type(s) of injury is this referring to, how long is too long and how widespread/likely it is?
I've been looking on and off for a pair of ANC earmuffs for factory work, but reports that some people experience headaches combined with the pretty high price have caused me to keep putting off the purchase.

Not to people outside your truck though..
Common rail diesels are very quiet compared to older style diesel engines. Some are so quiet you wouldn't even know it was a diesel. And with DEF you won't even smell the classic diesel exhaust smell. The loud smelling ones are due to modifications and probably also from "deleting" the DEF (which is illegal).
It’s relatively quiet but still has that distinctive diesel sound. It’s the latest Cummins 6.7 and for something that puts out almost 400hp it’s pretty quiet. I’m fairly sensitive to noise so between that and the ANC I’m pretty happy.

In general, anything heavy related to headphones = bad.
You can get the equivalent of state of the art ANC performance with a pair of passive IEM's that fit properly.
Try using memory foam tips if you have trouble with tips fitting your ear shape.

Yeah they’re also very poor in terms of aerodynamics by necessity. A tonneau cover helps more than you might think!

Recently I started a job that has me using a headset with ANC (active noise cancellation). It was OK for the first week or two but then I noticed my head hurt. My ears felt full and I had ringing in my ears that was quite loud. I have mild (self-diagnosed) tinnitus but this was beyond that by a significant amount. I'm aware of how noise cancelling technology works it's by creating an opposing sound wave of equivalent…
Try IEM's.

#50Is this a heat engine? Feels like it has to be obeying the laws of thermodynamics and something has to get hot managing the pressure wave density in air. I'm guessing the speaker magnets and coils heat up. Play enough noise, and the system will explode into fire...
Audio is basically negligible in terms of power.
Those massive stacks of speakers at an arena rock show are (in total) perhaps 20kW. The lights use far more.
Earbuds can we well south of one watt.
