I just realized that in the course of a normal day I no longer have to deal with cathode ray tubes (CRTs).
Over the weekend while relaxing in my hotel at my family reunion in Branson, Missouri, I found the worst CRT television set I had heard in quite a while. Every time I would change the channel, the set would emit a piercing high-pitched noise that my parents could not hear. My brothers and I felt tortured by it, especially my youngest brother Jon.
At Olin, Prof. Gill Pratt taught me that the high pitches associated with CRTs are horribly annoying to young people but are impossible to hear in old age due to a lifetime of overexposure. But I think that may change in the near future.
CRTs are not a wonderful technology. They have created a worldwide chemical disposal problem and they eat up energy in a wasteful large form factor made of shatter-vulnerable glass. But finally they have started to get replaced by better technologies like plasma, LCD, and organic LED (OLED) displays.
Every day, the only displays I usually interact with my Apple monitor, Dell laptop, and my parents’ new little HDTV, all of which are LCDs. Thus, I haven’t heard that infernal high-pitched whine in some time. Now I find that I have fewer headaches and often feel more relaxed.
So my challenge to you is to find a CRT monitor in your life and consider transitioning it to a better technology. You just might make your life a little more pleasant.
