Rambling thoughts on sonification (use of sound for data representation) as a mode of communication.
In an email correspondence with Gregory Kramer (“maestro behind sonification”- http://www.abc.net.au/catalyst/stories/s1214931.htm ), he remarked, “There is a strong visual bias in our culture, particularly in how technology is configured. We just don't think aurally, at least not yet. Also, I think the sonification solutions are not yet all that good.”
I think of my scooter and I chuckle! So many times by the sound it produces I can tell that the petrol poured lacked quality, the sound that the door makes, tells me who has come in, the sound of the bucket filling ..such examples from daily life reaffirm my faith in usage of sound for real time communication. Though it is ironical that at the same time we are struggling to reduce the noise, in vacuum cleaners, car engines, doors almost everything. Trying to make a sound proof world. We are trying to make our acceptance of sound even lesser, hence more and more sound will be perceived as noise, which makes the designer’s job even tougher. (....)

This conclusion -- that the test location doesn't matter -- is different than the usual lesson from market research, where you find different results in different regions of the country.
Why does usability differ from market research when it comes to the number of required study locations? Because with usability, we test behavior, not opinion. Further, we test that behavior with a defined artifact (i.e., a specific user interface).
…In most cases, differences are due to diversity in the users' circumstances, not to geographical variation. It's therefore best to recruit a diverse set of users: some experienced users, some novices…

One computer left on 24 hours a day will cost you $115 - 160 in electricity costs a year and dump 1,500 pounds of CO2 into the atmosphere.» If you buy a new computer, consider a laptop. Laptops use only 1/4 the energy.
A tree absorbs between 3-15 lbs of CO2 each year. That means that 100-500 trees would be needed to offset the yearly emissions of one computer left on all the time.
