Have Object, Need Category - Pair of Parabolic Echo Mirrors

    Have Object, Need Category - Pair of Parabolic Echo Mirrors

    I've been sifting through the Categories index, looking for an appropriate place to post this. Any ideas?

    Outside a nearby science museum is a pair of parabolic dishes, each about 8' across, about 50' apart, and pointing directly at each other. Whisper into the focus of one and you can be clearly heard at the focus of the other.

    Suggestions for where to post this? Searches for "echo", "mirror", "science", "technology", "math", "reflect", and other words that came to mind left me with no good options.

    I expected that there would be a category of some sort for audible anomalies ... places to hear echoes or other things that reflect sound in interesting ways (tunnels, pipes, etc). Hmmm ... Audible Anomalies sounds like a good category name, come to think of it ...

    Ideas?

    Create a new Group

    I can't think of where this would fit currently. There may be something.

    I wonder how a category like this might flesh out but if it was well written and defined it might make for an interesting cat.

    Unless there's a category already -- and I can't find one, either -- I'd say it sounds great.

    Re: Have Object, Need Category - Pair of Parabolic Echo Mirrors

    I wonder if there would be enough interest in a group for "outdoor science experiments" or "teaching aids out in the field" for lack of better names. It seems intriguing to me at least.  Maybe ask the officers of the science museum, Foucault pendulum, planetarium, and any other science related categories for ideas & suggestions.

    Do you have a picture or link to the item? Maybe it could fall under one of the art/sculpture categories?

    I wouldn't limit it to outdoor, I took a tour of the Capitol, and there was a place where you could whisper and it could be heard across the room.

    Maybe Vortex and Mystery spots?

    I would not use Vortex and Mystery Spots as the title of a new category because of the existing Vortexes, Mystery Spots, and Gravity Hills category.  If you were recommending that category as a possible place to submit, it seems to be limited to optical phenomenon. (though I could see that category expanding to accommodate  others)

    What about Ringing Rock in PA. Would that somehow fit into this category? I'm a few hours away from there and probably wont make it out there this year but its a very interesting place. I wouldn't doubt it if its already been waymarked. Swizzle

    Re: Have Object, Need Category - Pair of Parabolic Echo Mirrors

    Of course this could be included in a waymark for the science museum, but that's not the same as having a category that focuses on the unique attributes of this site. 

    My concern is that there might not be enough sites to support a category devoted to "auditory anomalies" alone.  You would also need to write the category in a way that would remove as much subjectivity as possible, so you don't get the waymark, "Hey, I came across this place and it echoed or made a funny sound."  Or, maybe that IS what you want.  A discovery category.

    Possibly the suggestion of outdoor or public science demonstrations could work.  I know the National Science Museum here in Korea has some that are interesting outside.  Interactivity might be a requirement, or at leas a variable.  Suitable for children.

    Definitely some good possibilities with this!

    I was the expanding I was thinking of. It seems like sound would be a logical expansion to visual.

    Re: Have Object, Need Category - Pair of Parabolic Echo Mirrors

    What about a catagory to do with World War I.  I remember watching a programme about these on the south coast of the UK.  They were early listening devices for approaching aircraft.  They were used before the invention of Radar....

    Send Scooter Bill an email. He's the group leader for Vortex's, etc. I think it fits the category as is. If not, perhaps he can be persuaded to expand the category.

    But these acoustic doodads (in the OP) are not physics gone wild.

    They're engineered around the properties of sound. Engineered.  By people.

    Like Carnegie Hall.

    Not the same as constructing a road in a place where it appears that water runs uphill.

    I don't think that they should be in that category with Gravity Hills.

    I always thought those "Mystery Spots" were fabricated tourist traps.

    Growing up my parents refused to stop at one, because they were a waste of money.

    The first thing I did as an adult driving by was stop and pay. I have to say I felt it was one of my bigger wastes of money.

    Well, maybe the "proving you parents were right..... priceless" comercial

    Would you be referring to the one in Irish Hill, MI?
    It is pretty hokey, but if you bring the little ones it's much more fun seeing it through their eyes. If it weren't for our son, we would have left two minutes into it.
    But you're right, most of them are engineering to obtain the desired effect.
