Good to know! We bought a few with integrated 10-year batteries from Home Depot a few years back, but I didn't realize you could get regular lithium 9Vs that last that long in a smoke detector now.
You should replace the smoke detector after 10 years anyway so buying the disposable ones is probably safer.

I have some hearing damage with mild tinnitus and find it hard to follow discussions in noisy environments (bars, very noisy public transport, even some restaurants). Custom fitted flat frequency earplugs are the perfect help for these situations, I always carry them in pocket just in case.
Would you expound on this a little and perhaps mention some brands? I also have issues following discussions in those kinds of environments. I can hear the people talking, but it blends into the background noise and becomes very difficult to isolate the actual words.
Not the cheapest but if you don't lose them the should last a decade.
Let me know if you have any other questions!

I mean, the actual implementation of this feature could have been a few hours work... Let the media center detect airbag deployment on CAN bus, then play a pre-saved quarter second audio sample at a fixed volume. There might be complexities if the audio system is turned off and needs to boot up, but my guess is on all modern cars, the audio amplifier etc. is always turned on, even if the radio appears 'off'.
> the actual implementation of this feature could have been a few hours work... Yeah, but nothing in the car world is that easy. First you need to fit this to all cars. Then you need to test it (not that cheap), document it extensively (safety level, failure states, activation conditions, ...), check that it actually does what it's supposed to do instead of for example worsening it and then you need to get it certifi…
And it's the kind of feature where if it only activates 98% of the time, or sometimes triggers incorrectly, it's not really a problem.
I just want to say that this is exactly the type of thoughtfulness, design, engineering and research that justifies the price difference in something like a Mercedes and something like a Honda. There are so many small triumphs like this in class-leading, high-end vehicle manufacturers that go unnoticed and unsung and allow people with 2019 Accords to say things like "why would I pay $45,000 for that when I get better…
Even the C-class is pretty impressive (I got one and optioned it up because the E class is a bit too big for my city garage). I really, really appreciate just how freaking quiet it is inside when I’m driving downtown and how road noise is low even at freeway speeds. That’s got to be good for one’s hearing. And the safety record is impressive, not a single recorded fatality according to US government records despite i…
I'm guessing an engineer named it the German equivalent of "pre-crash" sound, then someone in marketing decided that "pre-safe" sounds better. It may be better to call it "foreplay" sound, since if you ever hear it you're probably screwed.
Some technical disciplines use "safe" as a transitive verb meaning "to make it safe", either from damage or from damaging other things. I've seen it most often in rocketry contexts - you "safe the rocket" in an aborted launch scenario so it won't go off accidentally, etc. "It is a good idea to add a safety release valve to your launcher. Sometimes it is important to abort a launch and safe the rocket after it has bee…

Another good reason to barbell bench and skip the machine!
Or dumbbell bench with those heavily rubberized weights. Dropping them is about as close to silent as you can get, and the exercises are the ultimate in form-focused weight training.
They're called bumper plates! They're so you can drop a loaded bar without causing everyone to glare at you - and also to help avoid the plates bouncing onto your foot.
But you shouldn't need these on the bench. If you bench without a spotter and get stuck, move the weights to your hip and then sit up and shift them slowly to the floor like you're finishing a deadlift. (I've always called this the 'strongman escape' but it has no formal name afaik)

That's a good idea! I bet if someone were to develop a residential smoke detector that did that it would sell well. (Especially if it had other compelling features like a 10-year battery.)
I’d be happy with one that gives battery alerts at less than maximum volume.

I recall reading that discussion when it was first posted. There was something I didn't understand at the time, and now that it's brought up again, I want to ask: He mentions there being a fairly short window in which an ENT physician can try to treat the damage, after which no treatments will be possible. I thought all hearing damage was permanent, always, notwithstanding the potential new advances in growing the ha…
This comes up fairly often on tinnitus fora. Basically there is some "consensus" that a shot of steroids within a very short window, ideally less than 24 hours, can help. Unfortunately, the most common response to damaging one's hearing seems to be to sleep it off for a week and hope it gets better, making it difficult to conduct a study on early responses. There are studies though, and my conclusion is that it's sti…

The bumper plates are also round, which makes it easier to get a deadlift into position, and makes it land better when doing reps. The first 45 is a bumper plate, then add regular plates from there.
Resist the urge to bounce off the bottom of the rep! :-)

Then go buy the toilet lids that don’t drop with the acceleration of gravity, i. e., “soft close”. Hearing loss or not, I don’t want to hear anyone dropping the toilet lid in the middle of the night.
The culprit was actually a lid on the tank . I've never seen a toilet lid, soft close or not, that doesn't have plastic pieces that prevent full direct contact between the lid and the part below it. They'll deform under pressure, taking the noise level down from unbearable to just loud.
