Use a painfully loud noise when performing a forced entry
Whenever police need to force entry into a house, they
should turn on a painfully loud noise just as they break
down the door.
All of the police officers would be equipped with noise
canceling hearing protection that cancel out the sound
frequency in the alarm. For that reason, the alarm
probably be a single frequency, so the officers' hearing is
affected as little as possible. The sound might be pulsed
or modulated in a way that can be easily tracked by the
noise canceling headphones. The headphones might also
provide sound amplification of other sounds as well as
communication between officers.
The police officers would have remote control of the
to turn it on and off, as well as it being monitored by the
This is intended to have several benefits.
1) The suspects in the house being invaded will be less
to resist with their hands over their ears.
2) The sounds coming on suddenly might somewhat mask
the sound of the battering ram, making it harder for the
suspects to know for sure if it is them or their neighbors,
and/or which door the police might be coming in. In
general, adding a lot of confusion for the suspects.
3) For suspects who are innocent and completely
by the fact that police would be breaking down their
this system would be widely advertised before being
so it would give some assurance that the people breaking
in are actually police, not just home invaders
impersonating police. They can stand with their fingers
their ears while the police clear the rooms. Then the
police can hit the off button before they put handcuffs
or otherwise remove people's fingers from their ears.
It is somewhat unlikely that robbers impersonating police
officers (which seems to be becoming more common
where I live) would want to attempt to duplicate this
sound. It would require a lot of gear to protect their
ears and would alert the neighbors. The city could even
install a network of microphones, say every half mile or
something so that any such alarm can be detected.
Whenever the police use this for forced entry, dispatch
would be notified, so any unexpected alarms would
automatically bring the police to the site.
These are kinda a similar effect, but a bit more crude... [RayfordSteele, Jan 17 2019]
||I like it, except the "widely advertised before being used"
part. Surprise is better.
||Y'know what really grinds my gears? They've made it illegal here now to have an out-swinging front door.
Yep. Doesn't matter if that second and a half of back-draft was all that stood between life and death in a fire situation... as long as cops can knock that sucker in.
||Another little legal gem just imposed across Canada; the police now have the right to enter your home and force you to take a breathalyzer test up to two hours after having your vehicle reported by anyone for suspicious driving!
Can nobody see how open to abuse that is?!
When I was growing up there was this waitress my mom knew who hated her ex So much that for years she would stalk him and then steal the plates off his car and get it towed.
This would let anyone who knows your vehicle to make a call when they know you are on your way home from work on a Friday after grabbing a few brews to completely and utterly fuck your life over out of spite...
||Anyway sorry for the mini rant.
Uh, audio attacks as they storm the in-swinging front door of my home with flash grenades, tear gas, and laser blinders at their disposal?
Sure why not.
||This invention would require the development of noise-
canceling headphones for dogs, since they're likely to be
involved in any good bust operation.
||Apart from that, it might be useful for breaking
communication within the target building, e.g. "flush the
drugs!" or "release the tiger!".
||I like the part of the siren being drowned out by specific
frequency cancelling headphones. I had a sort of similar
idea for a visual equivalent where a battlefield is lit up
with random synchronized blinding flashes that were in
sync with the soldier's glasses that darkened with each
flash. So the soldiers would be able to see fine, they'd
just see the occasional split second flicker as their
goggles blocked the blinding flashes but the enemy who
was not so equipped would be constantly blinded. They
would be completely random so you wouldn't be able to
time blinking your eyes.
||Add the sonic equivalent, perhaps a deafening shrill horn
that turns on and off in sink with on / off noise blocking
earplugs and you've made the battlefield very hard to get
around for the enemy.
||Could use the blinding thing for law enforcement as well.
||[2 fries] the door-law sounds horrific. Is there a provision in
the law for the additional exterior screen/storm/security
type door? By necessity, they're outwardly opening. My
screen door is steel with an ornate wrought iron-style design
that concentrates around the lock area preventing access.
It's lockable from both sides and would make getting in a
longer process, I suspect you'd be forced to bolt-cut your
way through it. I was also pleasantly surprised that we have
hinges with tabs that interlock when the door is closed, a
good legacy of the neighborhoods past I think.
||Doc, I like the random flash idea. Working in defense
vehicle engineering as I do at the moment, I might
kick it around and see what feedback I get.
||Welding helmets can react fast enough to dim
welding flash without any fancy timing.
||One minute you're sitting on a rock, singing beguilingly. Next
thing you know, a half-ton perforated paddle comes whipping
down and splats you. Ungracious, I call it.
||//Use a painfully loud noise when performing a forced entry//
||Initial worries this might have something to do with Harvey
Weinstein (on reading that) proved unfounded.
||Yep, you can build an exquisitely hard to breech screen door [bs0u0155], but if the main door needs to swing inwards to access it in the first place... and 'out' is the place you need to be, then... in my mind... who the hell has the right to tell me, (on my dime mind you), how to build my own door on my own damn property that I damn well bought and paid for?
||'More' sirens might be good though too.
||// What has any of this to do with flies? // Sorry, I guess
that should have been SWAT, not Swat.
||I thought about the blinding flashing lights thing as well,
but the primary purpose of this idea is to help deal with
the deadly situations that arise because of the need for
police to occasionally force entry combined with the
number of news reports lately that I've seen where
intruders claim to be law enforcement. The big thing
about the loud noise is that it announces the police
presence to everyone. A badge or a warrant can be
faked. While criminals could also use an earsplitting
noise while robbing your house to pretend to be police, I
expect few most would hesitate to announce themselves
this way to the neighborhood and any nearby police.
||If this were primarily for tactical advantage, then yes, it
would be best to surprise people with it (not advertise it)
and blinding lights would be a great addition. The point
of advertising it is so that people know that it is the
Police, and know not to resist. Also the neighbors would
know what's going on. The lights are fine except that the
light would likely not be noticeable a few houses away, so
criminals might not hesitate to use the same technology.
||//should have been SWAT//
||Hey! You spoiled my WIFRT!
||//Doc, I like the random flash idea. Working in

||Well, it's public domain now, let me know if you get
||I'll also take that as an olive branch and of course, I
accept with a respectful virtual handshake.
