Audible glide angle

[riggerrob 643]

Different people absorb data in different ways.
For example, I absorb data rapidly if its presented as angles. Have you ever noticed that the better automobile speedometers display city speed limits with the needle near horizontal and highway speed limits near vertical?
I absorb data slower if it is presented as "beeps" per second.
I absorb data slower if it is presented as "changes in pitch" (musical tones).

Pure numerical data is almost gibberish to me.

Would it be fair to say that you absorb data slower generally when it's auditory, or can you think of an audible indicator that is not rate or pitch change in a tone? One thought is the method where the device dictates the glide angle to you as a number, but I assume this would fall under the category of "pure numerical data"?

A visual signal would be interesting to experiment with, but I don't think is practical for me at this point.

I was looking at the techincal data on the SportVue used in the Altimaster Titan, and it looks like the LCD screen which is being projected in front of you is of the "custom-tooled" variety and not just an array of pixels. This has the advantage of higher resolution, but comes as a bit of a disappointment to me because it means less flexibility in the display.

I've ordered a relatively cheap pair of Etymotic Research ER-6i earphones, which are the in-ear type. This should reduce outside noise by about 30 dB. The earphones themselves are very sensitive to voltage, which means I might be able to eliminate the amplifier from my system. I'm pretty stoked to see what these things sound like.

Edit to add: With the in-ear earphones, I've also considered that this will make an audible altimeter almost inaudible. I'm thinking I will have the device dictate altitude every thousand feet or so, as well as a distinctive tone at pull time. Obviously this is not the only altitude reference I use, but should help keep me from fixating on the other data.
