Funny, if you actually sampled an entire trading day, you would hear the "drop" around 2PM.

There are some traders that use sound alerts when trading short term, either using alerts on the NYSE TICK, or aggregating when certain companies are being hit on the bid or ask.

Lots of fun.

This really needs to be properly EQ'd though. Watch these tutorials, and you will be able to make the thing sound 10x better with ~30 minutes work. It doesn't matter that the tutorials are for guitar music and are using specific EQ plugins, the advice is universal. Once your spectrum is less saturated, you'll be able to dial back the limiting as well.

I've done about 4 years of research on sonification, which is using non-speech audio to represent patterns in data (http://mags.acm.org/interactions/20120102/?pg=37#pg37 for some specifics). This article is a subset of sonification in some ways, since we're representing some quantitative data using auditory parameters.

There's an entire class of scenarios where conventional HCIs can't represent data for analysis: where people have an occupied visual sense (doctors during surgery), where people are mobile, where people are overloaded by visual data (stock analysts), where the visual sense isn't suited for extracting data from noise (during the Voyager 2 mission), etc. We tend to rely only on our visual sense for communicating data, and as we start using computers for data display in more places, we're reaching the limitations of conventional HCI.

My research was on proving the viability of sonification - looking at the accuracy of comprehension, the cognitive and physiological processes, demonstrating shared mental processes with visual graph comprehension, etc. It's still something I'd love to revisit and commercialize someday.
