I was watching RWBY and noticed Velvet and the end of S2 ep 8 has two sets of ears one normal human and the second is Rabbit. This isn't the first character that has it. all of the cat girls from Asobi ni Ikuyo (cat planet cuties) and Koneko from High School DxD have them too. I was just wondering and this is just out of curiosity but.........

Do both sets of ears work? or is one set real and the other just for decoration?

If both work does it give them better hearing than just one set or does it echo in their head and if only one works which one? and will that give them problems normal people don't have? like inner ear infections, or increased chance of dizziness since the ears are responsible for balancing the body.

I feel like there'd be no functional point in having them of they don't work.
I expect they'd just have slightly better hearing.

why are you asking here? ask the creators :P
But then again that wouldn't be fun

I guess it would mostly apply to them having sensitive hearing like rabbits, cats, n dogs. and im guessing they can get an ear infection in one set of ears while the other doesn't but it still affects how they hear. I remember in TERA the elin race also has two sets of ears, their animal ears and normal ears.

well assuming they have cat and human ears....
higher frequency response from the cat ears. also better directional repsonse from cat ear forward.
i would thing humans might have better all around hearing, directional wise.

then there is the fact that they can hear in 3 (assuming the same cat independent ear movement) vectors, two cat, one human.
basicly a quadraphonic hearing.

assuming you can get data from all 3 vectors, and process it. (humans very rarely process audio signals in the visual cortex, leading to things like human ehco location and the ablity for the totayl blind to play sports, jump on poles, ect)

assuming a cat girl's brain can process it, you would have 3 inputs, you might get things like being able to hit a target blindfolded. humans can shoot blind with only hearing, and get pretty close. thats with bi aural. fixed vector hearing. with quad aural, tri vector hearing, who knows. but alot better hearing. i would assume its like modern sonar, or better. you know, target identification, range, bearing, elevation, reletive momentium.

anyways, that my take on it.

That because a loli needs cat ears for cuteness overload.

The first time I saw a character with both cat and human ears, the first thing I thought was that it must be weird to have four ears...

Evolutionarily speaking I think it is a dead-end. There would be no real advantages gained, except for having a 2nd set in case the first gets damaged, and a lot of disadvantages for the person. Cat hearing is far superior to human. And combined with binocular vision and low light vision than adding human ears gains nothing. Think about it another way; what would be gained by adding a set of human eyes to the already superior cat eyes? Again double vulnerability with no real advantage. Now Holo (Horo?) from Spice & Wolf does not have human ears added to her wolf ones. (Or I don't remember any at least.) Also one would need a much larger brain to process all the signals from each ear and process them into a coherent picture. Personally I think it is from how the character design evolves. First draw a human that is your character than make changes to fit the alien mode: ears, tails, etc. Then they either forget to remove the human ears or decide to leave it. Or maybe it is just a device to remind the audience that despite being Alien they still are 'human'.

Cat ears make cute girls even cuter. I know they're fake, but I don't mind.

"Superior vision" is relative. Yes, cats have better night vision but humans have superior colour vision and see significantly better in daylight as well as having sharper vision across a range of distances. (see article: http://www.livescience.com/40459-what-do-cats-see.html)

Biologically it would be complicated but having a set of forward facing ears coupled with stereoscopic vision would make you a better hunter at close ranges while having ears set to the sides of your head would allow you to better locate more distant sounds. However it would probably be necessary to be able to turn off one set of ears while using the other, similar to closing one eye to focus on a very near object.

Of course, if catgirls have both sets of ears active at all times that might explain why so many are portrayed as being a bit ditzy. :P

The character that's got to be really messed up by this is Inuyasha. From what I remember, he only has one set of ears at a time, but switches between dog ears and human ears depending on what form he's in. That's got to be a bit disorienting.

True real cat eyes are not as good in some respects, but catgirls being upright bipeds eyes would develop on the human model for long range visiion, etc. So I was taking that into consideration. But there is ONE explanation we haven't explored. That the cat ears are NOTHING more than emotional state indicators. I.E the ears do no actual hearing. But I do like and concede the bolded and purple text of yours.

Wutt. ^^^

And even if evolution would take it's course, just because something doesn't serve a practical purpose in survival, there are many adaptations that serve no purpose in surviving yet have evolved. i.e. face blushing, as a sign of emotion, crying while sad, etc
So catgirl ears would probably persist if it helped them "socially" only if the only function is to be an emotional indicator, as it seems to be the cause between all catgirls.
