The Noise of a High Speed Train
There is quite a reasoned article on the BBC today about the sort of noise you might get from a high speed train on HS2 and how you could reduce it.
The article doesn’t mention a technology that by 2020 will probably be available to quieten the train and that is the use of anti-noise, where an equal and opposite noise is generated to cancel the sound of the train. I dabbled in this twenty years ago and even then the technology had been successfully applied in a few applications. But even if anti-noise itself is not used, in ten years or so how trains create noise will be better understood and better design will be used to cut the noise.
I may be generally against the building of HS2, but I do think that noise will not be one of its biggest problems.
Who Nicked A Mobile Phone Network?
Apparently thieves have stolen some crucial hardware from Vodafone, causing thousands to lose their service.
I suspect that many will think this is something more sinister than just simple theft, but I wouldn’t think it’s linked to anything like the company’s shutting down of their Egyptian network.
Could it be just for the copper? Or the other expensive metals in the equipment? If it is, we’ll probably be seeing other attempts at this type of theft.
The Telegraph are musing over the questions in this article.
What Does Her Majesty Think?
The King’s Speech has done well at the Oscars, winning four awards for best picture, best actor, best director and best screenplay.
The Queen has been known to have found the film moving.
We will probably never know what she feels officially, but these recently released pictures, show how close she was to her father.
