xkcd • View topic - "Loud Sex" Discussion
Alt Text: Spherical or parabolic reflectors would of course lead to aberrant behavior.

Yes!
It's hilarious!

I kind of wish I had a roommate who had loud sex, just so I could do this.
Actually, more importantly, I wish I had a girlfriend who wanted to have loud sex so as to concoct the aforementioned revenge.
In any case, this got a chuckle from me.

Bonus points to the first person to prove that an ellipsoid reflects sound waves emitted from one focus towards the other focus.
However, shouldn't it be an ellipsoidal reflector rather than an elliptical reflector, or do they mean the same thing?
Or is it elliptical rather than ellipsoidal because the world of xkcd is 2-d?

Yes! Totally brings back memories of those dishes they had at the science museum where you could whisper into one and someone else would be able to hear it at the other dish, even though they were several yards apart.
I found those things so much fun.
Now I know how to put them to use as an adult!
Floop.

There's a major problem with this plan...
The situation is symmetric.
Any noise the neighbor makes at that point will be equally inserted into the sexcapades.
However, I will concede that with the state of science education in the world, odds are extremely good that the neighbor won't realize this and take deliberate advantage of it...
Say, with an air horn or other such, ah, unsexy choices.

Re: Symmetric
That would only work if it were a complete ellipse, or if the other person had a matching reflector.
Since it's only a small section of the ellipse, and it's only on one side, the sound increase that our heroes will experience is negligible.
(In other words, sound going in almost all directions from the left will go to the other side, but from the right, only the waves that are traveling in the general direction toward the left will be amplified.)

Ellipsoidal instead of parabolic because of the short distance involved?
(and how much does scattering from the walls affect this?) Why do you assume that I exist?

Too bad the directivity will be lost as the sound waves pass through the walls.

Yes.
Ellipsoids reflect waves from one focus towards the other focus.
Paraboloids reflect waves from one focus to the point at infinity (or vice versa) which is a good approximation to the actual position for very distant objects such as stars and planets, but not a very good approximation for near objects like the person in the adjacent apartment.

But from the right, only the waves that are traveling in the general direction toward the left will be amplified.
If the sound is already directional, then all the waves are already headed for the reflector, hence my airhorn example.
Sound only radiates uniformly from a point source in Physics I problems.
This is totally exploitable by the neighbor.

those are parabolic because they require the concentrator at the other end.
The sound in between the two is horizontal.

Ah.
Forgive me. I lack skillz beyond those obtainable in Physics I.

I think the real benefit of this scenario would be the next day, walking around public places and whispering sweet nothings covertly into stranger's ears.
As covertly as anyone with a huge elliptical can manage, anyway.

I'm sure you could technically achieve the same results with out the girl;
It just wouldn’t be as fun.
I like how you can actually see the words reflecting of the dish.

All I know is high school physics would have been MUCH more interesting if we reflected sex noises instead of candlelight.
Caliman, I must also express my appreciation of Josh's aviator.
I've heard he's a very skilled pilot.
I'm sorry, I had to do it...

In my experience, having a girlfriend and constructing an elliptical reflector are mutually exclusive events.
Maybe it's because all my girlfriends have been chemistry nerds though....

The walls would serve to disperse much of the sound.
This would be far more effective if done in the room with the neighbor.

XKCD GIVES STEP 2!!!!
1) Get loud girlfriend
2) Install an elliptical reflector dish <---- STEP 2 IS NOT "????"
3) PROFIT!
This is truly a momentous occasion.

The sum of the distances between the foci and any point on a surface of an ellipsoid is the same for all points on the surface.
Since the distance by any path from one focus to another is the same for all paths, the time sound takes to travel from one focus to another is the same for all paths therefore all waves arrive at the second focus in phase.
Since they are in phase they constructively interfere causing the sound to be as loud as it was when it was produced.

I'm unsure as to the "Profit" section?
Is this profit entirely made up of vengence?

Quote: : Why does the protagonist suddenly have hair when he is having sex?
He had hair before, it was just slicked down.
And it got messed up during sex.
On a side note, I could really go for some loud, messy-hair sex right now.

Just what I needed before work.
Hilarity! Oh, and now I'm also thinking about loud sex.
Anybody ever had sex so loudly that the person next door thought was a burglary or ...
Erm, an.. "attack" ?
Still, awesome in comic-land.
Not as awesome in RL, but a great strip.

No, but I once was applauded from the other side of a wall.
Well, technically I suppose it was my girlfriend who was being applauded, but I felt like I deserved the applause just as much as she did.

Hmm, the reflector dish needs a slight tilt.
According to the shown diagram, the sound barrage will miss, if Loud Neighbour lays her head on her pillow.
BTW, I particularly like the arrow label "Loud" in panel 3.

It's these very subtleties, that I miss the first time around, that really make XKCD for me:)

As for the subject at hand, this comic does indeed win the internets.
Life in a box is better than no life at all, I expect.
You'd have a chance, at least.

Being scientifically minded enough to build the reflector int he first place they clearly preempted the problem and...
Um... moaned... backwards.

Surely our protagonist can be relied upon to compensate for this?

I was saying to a friend the other day how I thought XKCD wasn't as good as it used to be.
I didn't really like the braille, dating pools, insomnia or the Robert Frost comics.
This one is really great, though.
I hope we get to see more like it.

Why can I not see this comic on the main site?
I think I've broken my Interwebs.
I had to remember that the comic is posted on the forums just to see it.
This is worrying me, and I really don't need stress right now, my brain is full of worrying about uni and trying to work out why sound from one focus of an ellipse should always go toward the other focus.
Damn science.

I think a lot of the xkcd is so good because it touches subjects you thought you were the only one thinking about.
Walking on specific floor tiles, thinking about things such as curse levels, hamster balls and running up escalators.
I could relate to insomnia and colored lights...
And the dating pool!
