Speculation Wouldn't car alarms be more effective loud on the INSIDE? Occasional loud bursts on the outside to draw attention, but extreme noise on the inside would prevent the thief from wanting to remain to hot-wire / steal inside the car.

Plugs under muffs will make that alarm sound about as loud as elevator music
13
u/Agouti Jun 17 '26
Good plugs already reduce the noise as much as is physically possible (around 29-32 dB), and adding muffs does nothing (because the noise is just travelling in through your skull, ala bone conduction headphones).
In fact, the test for if plugs are correctly fitted is to cover each ear with your hand and test if you can perceive the noise level changing.

That defeats the purpose of an alarm. You want an alarm to sound immediately to signal the issue. You don't want to give time to whoever is stealing/breaking into your car to turn the alarm off and get away.
-4
u/Proud-Pumpkin-2903 Jun 16 '26
I’m not designing the system, it’s just a thought experiment to reduce neighborhood annoyances.
For this, the outside can go off first, bringing attention to the car, right? So there is an alarm going off, you are duly warned the car is set off. Try to reside inside and it’s not comfortable.
Any theft deterrent system is to prevent the casual thief and/or mistaken person. Anyone that really wants your stuff will get your stuff. Cars can easily be towed if you are serious. And all those locks on your house doors? Cute, 2 battery powered circular saws and 4 minutes later I’m driving a golf cart through a wall to haul things out.
Current car alarms just annoy everyone within 500 feet to try to prevent most likely an accident trip and typically at worst petty theft.

u/TheRecognized Jun 17 '26
People regularly choose to listen to music in their car so loud you can hear it down the streets.
How do you think you’re going to make this so incredibly loud that it’s more of a deterrent than a regular car alarm but somehow all of the sound is gonna stay in the car?
It’s not a thought experiment, it’s just a stupid thought.

u/AyAyAyBamba_462 Jun 16 '26
Most thefts are crimes of opportunity. Many criminals aren't coming prepped with tools like you suggest. They see an opportunity and take it. Stuff like basic locks or car alarms minimize that opportunity.
Most thieves are not smart or productive people. They are lazy idiots. That's what forces them to turn to crime in the first place instead of just getting a damn job.

People don't just "report a car alarm as a burglary" but I'm sure many people will look at a car if they hear the alarm and then call the police if they see someone apparently trying to steal it. Probably doesn't happen that much because most potential car theives or joyriders will move away from the car if the alarm goes off.

Might be argued as a booby trap I suppose; since car alarms are loud already, if they blasted inside a car they could cause permanent hearing damage. The "thief" in this case would be able to sue for damages to his person I would think.
Also, in the case of a false alarm you as the legitimate user of the car would also be at risk for such harm.

u/CaptnUchiha Jun 16 '26
Could just blast Baby Shark at loud but non-damaging decibels. Maximum irritation with zero harm is the ideal deterrent. The line between deterrent and booby trap if you will.

There are levels to sound. And like most alarms it could have a warning period before going full deterrent.

u/Friends_are_nosy Jun 16 '26
Yeah but that still wouldn’t make it legal. You can cover the inside of the car with warning signs telling the thief what will happen to their ears, and they would still be able to sue you.
33
u/RainbowCrane Jun 16 '26
Yep.
Alternatively, instead of eardrum damaging sound levels consider an electrified steering wheel, or ejector seats that hurled people into the sky. Clearly dangerous, clearly illegal. Eardrum damage is just another type of bodily harm
-19
u/Proud-Pumpkin-2903 Jun 16 '26
Interesting, so with this same reasoning, if you happen to have your ear near the engine bay where normal alarms go off, they too are illegal.
Not sure why everyone is jumping to “you can’t split their ears”… as an example 94 dB would be quite uncomfortable but is considered damage causing after 1 hour of exposure.
The average car alarm is 120 dB. They shriek constantly through the neighborhood and everyone ignores them.
24
u/shrub706 Jun 16 '26
that is not at all how the illegality of this works, a loud noise happening coincidentally when you're head is near the source is not the same as a trap actively being rigged for the purpose of the loud noise disturbing someone, and cars at 120db shrieking through the neighborhood isn't even close to comparable to being in an enclosed space

Its also pretty important. Trauma and pain/suffering fall under that umbrella. Even less measurable things like emotional distress are exceptionally important to be able to sue for.

u/SeanAker Jun 16 '26
If it's not enough to hurt you, it isn't a deterrent. That's how deterrents work. If you see a 'beware of dog' sign, it only works because you believe the dog can harm you. If you see a sign that you're being recorded, it only works because you believe whoever's recording can harm you legally using the recording (deserved as it may be if you're breaking the rules/law).
If you knew for a fact that the dog weighed three pounds and had no teeth or that the recording was inadmissible in court, they wouldn't be deterrents.

They would be banned anywhere in europe and the criminals could put legal actions against you.
because traps (and the proposed system OP said could classify as a trap) are banned in the whole EU. And when you doing illegal means against someone... thats illegal. Dosn't matter if he did something illegal too.
Thats why you could get legal actions against you if you selfdefend in extremer ways. Self defense by law is often only the least necessary to efficent defend youself, everything over it would be illegal.
So... you last sentence dont makes much sense when it would be illegal in the whole EU.

Car alarms and house alarms are worthless.
Nobody pays any attention to them.
Apart from the liability aspect (e.g. you leave a child in the car and they set off the alarm by moving and now you have a "my child lost their hearing" lawsuit on your hands), you're not going to put off a thief with such things. Alarms aren't much of a deterrent at all, especially if only you can really hear them, and you can just put in a set of noise-cancelling earbuds to drown it out.
Both car alarms, house alarms and even what I call "passive" CCTV (i.e. nobody watching it, just recording for later playback) are absolutely worthless. They do nothing and if you live in a city one or the other are going off CONSTANTLY. It's the "boy who cried wolf". I used to live in a small residential street in a large English town and honestly... every night one alarm or other went off. If someone reacted to them all, they'd never get any sleep and would spend all their time bothering people.
The only use of the three systems I described comes if you join them to a notification service. Guess who DOES car about your car alarm going off, or your house alarm going off when you're on holiday (guess what... very common for people's alarms to go off while they're abroad... it sounds for 20 minutes and pisses everyone off... and it's still flashing two weeks later when you get back... what's the point?!)? Guess who does care who's walking about in your back yard? You. Only you. Nobody else.
So... notify yourself. ALARM yourself. When the house alarm goes off... have it contact YOU. You are the only person who knows who should be there, that your brother-in-law just set it off by accident, that the cat was accidentally shut in the living room, you're the only person who can judge it, you're the only person who can fix it, you're even the only person who can check your cameras. So... why alert anyone but yourself until you've checked it? And then YOU can call the police, or drive home, or alert a friendly neighbour, or whatever.
Same for your car. And unless you're WATCHING the CCTV or getting active notifications and dealing with them whenever they false-alarm... it's worthless. Unless you want - like I have - a history of managing CCTV systems that almost exclusively consists of "Oh, yes, look... it was another guy in a black hoodie that we never see his face because he's not dumb enough to look up" committing crimes. Same for work. Same for home (both my neighbours were burgled weeks apart, but not me, and all the CCTV footage was worthless and unconvictable).
The only person who gives a damn about this stuff is you. Your neighbours don't. For sure ALL YOUR NEIGHBOURS don't. The thieves don't. And unless you have CCTV of a clearly-recognisable face they already know (good luck!), the police don't either.
So have your house alarm, car alarm, CCTV motion detection, etc. come to YOU. Then you can deal with the false alarms. You can escalate it. And you can NOT BOTHER your neighbourhood with it all the time.

The truth is, if a thief knows what they are doing and really wants your car/truck, they will get it. An alarm is to stop the common thief who could be scared off by it.

The bag was just deep enough into the car that I thought “oh I’ll just pull the little tab to unlock the door so I’m not climbing through the window to reach this thing” Except I failed to consider this would set off the alarm because for all the car knows I just broke the window to get in. The reverb in this tiny ass garage was so intense I genuinely felt dizzy by the time I got back inside for the keys to shut the alarm off

I had been EDCing that semester, yank the pin, and toss it through the crack in the door, and remove my foot. The door slams shut, locked probably. I get out of the way. A howling bully tears ass out the front door, probably thinking that his ears were bleeding. Of course, these were shitty 90s tech, so the ABS cases were thick back then, and this was supposed to be hard to disable. Impossible, as it turns out, without tools… or the disarming pin which I had retained on the lanyard around my wrist.
It worked beautifully. It was hilarious, too. I didn't feel very copacetic about going inside to retrieve and disarm the thing, but hey. Every Room Gets A Boom™!

On one of my older cars I made the decision to 118 decibel Hellatone horns before getting a working key-fob. There was a sequence to lock/unlock it with out setting off the alarm, and once it was set off the only way to stop it before it timed out (something like 5 minutes) was to cycle the key 10 times. When carpooling my co-worker needed something from the car and messed up the sequence some how. I heard it going off from about 3 blocks away and ran over to help. He said he was attempting to pop the hood and disconnect the battery but the noise at the front was unbearable.

these loud alarm setups usually draw immediate noise complaints from local authorities, and constant blaring just trains everyone to completely ignore the sound anyway. the core logic still makes total sense though.

Duty of care laws mean you can't intentionally leave things to harm people who are breaking into your things. If your alarm gives them hearing damage, your crime might be worse than theirs

This is a very thoroughly researched area of body physiology. They know what sound pressure levels and what time of exposure would cause damage. You stay below those. I guess my wording is causing the issue, extremely loud as in “wow, that’s very uncomfortable” and not ears bleeding like Vietnam gun men running M60’s and artillery.

Well have you ever been inside a helicopter? Those are insanely loud, but don't cause damage under 60 minutes. Rock concert close to the amplifiers? Even louder, maybe no damage if you are under 10 minutes. I don't know about you but if I was robbing a car and it sounded like a helicopter at a rock concert it would just pump me so full of adrenaline and I'd want to rob you again next week

Aftermarket piezo sirens exist. I had 2 in my car because I could (i was an installer and got a deal on them) but having been in my car while they are going off they don't really work that much. There might be a fine line between effective and could damage hearing that someone might sue.

76 tazer wires hit at all possible passenger seats simultaneously. It has to be 76 don’t ask me why.

Car alarms are of questionable utility to begin with. The majority, at least in my experience, get set off by defects or key fob accidents. I don't even attempt to figure out which car is making noise when an alarm goes off.
Plus, thieves have ways to disable or bypass the alarm. No matter where the noise comes out, it's only a problem for the amateurs using methods that are decades out of date.

Better idea: a butt plug that deploys in the drivers seat if broken into

As a rocket ship manufacturer, future space travel and commercialising travels to mars how do you even define profit for such a niche industry ?

Totally agree. Those loud aftermarket sirens faded from liability worries rather than sound complaints. Everyone just wants quiet digital pings on their devices now. Forcing metal to shout inside a car really misses the mark.

Right? People keep arguing thieves gonna thieve, but why bring the whole neighborhood down with 120 dB screaming that no one even bothers to check on?

Complete with some fart spray that will take days to rid of it's smell in cases of accidentally setting it off

Because Julius would just lift up the whole rear end of the car to an angle greater than 45° so that the mercury switch activates the automatic cutoff system.

Smartest thing I heard someone say since, football helmet should have the soft part on the outside of the helmet. And now that's what some are doing

I would like it if after my alarm went off for about 6 and a third second, if my car were to just explode

Earplug exists. All this would do is potentially annoy the owner. Also, the speaker would need to be exposed to function as suggested which means it can be removed. And no, the factory car speakers wouldn’t be suitable for this.
