This is a concept of antinoise applied to the domain of smell.
This will be a tailormade perfume which completely cancels out a only one specific odour giving a perfectly neutral odour.
One will be able to have a custommade perfume to cancel out his/her body odour.
Note that this is not about
deoderents; Deoderents are different. They remove the odour causing bacteria in the sweat itself.

But you'd have to walk around in a fog of the stuff, which would have disadvantages. [mouseposture, Jul 05 2011]

mmmm... the English language and science. [-] |

How does this work?
Smell works by odorant molecules binding to
receptors in the nose. How do you "anti" that? |
|
| |
(Yes, obviously, devise a non-smelly molecule
that binds to and blocks those specific receptors.
Won't work, as just about anything binding to the
receptor will stimulate it in the same way as the
odour molecule.) |
|
| |
[-] unless you can come up with a plausible
mechanism. |
|
| |
The problem I see with this is that if you come up with something that could neutralize my manly and virile stench, the other sundry stenches will be competing for attention (sneakers, the natural fragrance from yesterday's chili cook-off, etc)... [ ] |
|
| |
If you smell like H2S you're probably going to attract
the odd "undesirable", like volcanic vents and rotting
eggs, I imagine. |
|
| |
In the domain of colors, black is exactly opposite of white. They cancel out each other. |
|
| |
Similarly, In case of sound (pressure wave), high pressure is exactly opp. low (or negative) pressure. |
|
| |
I am theorizing that in the domain of smell, it is plausible that, for a given smell, there is an exactly opposite of that smell; Both of these smells, when smelt together, will be odourless.
Which means this Anti-smell will generate opposite electrical waveform at receptors at nose. |
|
| |
How to find an anti-smell ? |
|
| |
Hypothetically, one way could be this :
Using oscilloscopes, analyse the wave form at nose receptors, which a given smell generates. Then find a smell from thousands of smells available (as Edison did for filaments) which generates opposite waveform pattern. Voila, that is (anti)smell we need. |
|
| |
there was an "ozium" or ozone spray which did this |
|
| |
//In the domain of colors, black is exactly opposite of white.// |
|
| |
Not really. One is the absence of the other, not it's opposite. (Which varies, for additive color schemes [light] black is the absence of white, for subtractive [inks/dyes] it's the other way around). There is no such thing as a dark light source that you can shine on an object to cancel out a white light source. |

Deode-rents? To anti-smell your apartment? |

//I am theorizing that in the domain of smell, it is

|
| |
Just very no. That's not how it works. You have
distinct receptors for different compounds (each
receptor picks up a collection of similar odorant
molecules). |
|
| |
What you're saying is like saying "If I hit the just
right spot on your left foot with a hammer, it will
create the exact opposite of the pain signals you
get when I stick a pin in your arse. All I have to do
is to find the exact combination and they'll cancel
eachother out." |
|
| |
A lot is already known about the olfactory system. |
|
| |
[spidermother] Since you expressed exactly my
own
opinion, I'll now
argue the opposite: |
|
| |
From your annotation, I conclude that the
substance
which is the oppsite of *every* smell is ...
aerosolized tetrodotoxin. |
|
| |
(Actually, nasal lidocaine spray exists. And
probably does impede olfaction <link>) |
|
| |
//Fine, but smells don't generate a waveform at nose receptors// |
|
| |
May not be right at the receptor, but later along the "line" to brain ? |
|
| |
All sensers utimately communicate with brain using electrical impulses. |
|
| |
Am I the only person here who thinks that this is one of the greatest ideas EVER? |
