Units of experience

THE hi-fi industry has always attracted small companies that sell magic-wand cures for poor sound quality, such as felt-tip marker pens that allegedly improve CD sound by absorbing stray laser light. The companies seldom offer any scientific proof of performance, preferring to imply that anyone who cannot hear an improvement can’t be a true connoisseur – so those who buy these audio cures prefer not to admit they can hear no difference and have wasted their money.

Reader Craig Wright has pointed us to the website run by Creative, a large company well respected for its PC sound cards and portable music players. Creative is now selling a device called the X-Fi Xmod, which takes in the sound from any desktop or notebook PC or Mac and “restores the details, expands the music to surround sound and creates an experience that goes beyond studio quality”.

The Xmod page on offers a chart that supposedly displays the result. Audio format – studio, CD or MP3 – is on one axis and “experience” is on the other. According to the chart, the experience of listening to an X-Fi-enabled CD or MP3 exceeds the experience of studio quality.

This leaves just one little question. How do you quantify experience? Or, to put it another way: does this chart actually mean anything? We find it hard to imagine what.

“London Energy writes to Peter Brown offering bonuses for meeting this challenge: “Reduce your energy usage by the same time next year…Your annual gas usage is recorded below. Annual Gas usage – 000000 kWh.” Can anyone help?”

Now wash the sound

MEANWHILE, Panasonic, the largest consumer electronics company in the world, tells us about a new home hi-fi system. This uses a “pure water capacitor for transparent sound reproduction”.

“Pure water capacitor helps improve sound purity,” Panasonic explained when we asked for some more detail. “With its high water content, this capacitor provides excellent electrical characteristics and… the clean current it delivers helps the speakers produce a clear, pure transparent sound.”

Oh so that’s it. To get clear sound you wash it in pure water. Doubtless it rates high on Creative’s experience scale too.

20 per cent of 200

NEXT, a puzzle. Dan McDougall, writing in The Observer newspaper, London, states: “There are also fears that even ‘eco-tourism’ is doing more harm than good. The WWF estimates that ‘only 20 pence of every £2 spent by an average trekker each day reaches village economies'”. Andy Woodwark, who spotted this, notes: “So that would be 10 pence in the pound, 10 cents in the dollar, 10 stotinki in the lev or, simply, 10 per cent.” Indeed. So what’s with this 20 pence of every £2?

Marginal scientists

IT SEEMS that the scientists at the University of East Anglia in the UK have at last been getting the opportunity to overcome their past marginalisation. Allen Jamieson draws our attention to a report in Sciencewise, the UK Department of Trade and Industry’s science policy newsletter: “Traditionally under-represented voices were specifically over-recruited [to a series of community workshops on science]. These included senior citizens, people for whom English is their second language, Portuguese immigrants, homeless young men, Black and Minority Ethnic groups (BMEs), young people excluded from the school system, young mothers and disabled people, as well as a number of scientists from the University of East Anglia.”

Sick without symptoms

ON the warning label of Donna Holmes’s bottle of aspirin is the sentence: “If poisoning occurs call a Poison Control Centre or doctor immediately, even if there are no symptoms”. Holmes is concerned that if she ever does exhibit symptoms of poisoning she won’t be able to get through to the centre because the lines will be swamped by people who are perfectly alright.

Recycling cycles

THE environmental group at Chris Hall’s workplace was hoping to encourage the use of bicycles by providing more cycle racks, but they had to clear the old bike sheds first. They posted the following notice about a bicycle that had been left unclaimed for some time: “If this bicycle belongs to you then we would ask that you assist us by removing it from the shed. If no owner comes forward, the bicycle will be removed for recycling after 10 March.”

Hall is intrigued by the notion of recycling a cycle and wonders if there is a word for this sort of thing.

Tiny symbol

FINALLY, the Action Group on Erosion Technology and Concentration announces a competition to design a “nano hazard” symbol. It points out that: “Biotechnology, nuclear power, toxic chemicals, electromagnetic radiation – each of these technological hazards has a universally recognised warning symbol associated with it. So why not nanotechnology – the world’s most powerful (and potentially dangerous) technology?”

Feedback has designed one of these already, as it happens – but sadly you can’t see it because it is a thousand times smaller than this full stop.
