Actually it looks much bigger on a log-log scale, if it was a linear scale it would be smaller than 1 pixel.
I think the point for me is if we could sense and process these higher frequencies we wouldn't need gadgets to convert the signals into things we can hear and see. Imagine having x-ray 'vision' you could 'see' through clothing. Imagine having infra-red vision, you could see in the dark. Imagine having microwave vision, you could see cosmic background radiation and the whole universe.
If you plotted other animals, the frequencies would hardly change, all they have is the sensitivity to detect smaller amplitude signals.
