Today I found myself in an MRI machine, where they scanned my brain. I hope the brain is still there, and I hope the MRI operators didn’t find anything interesting in there.
What else to think about for 45 minutes in this buzzing machine, where you can’t move, but thinking isn’t forbidden?
Right, I wondered how headphones could work in an MRI machine, the ones they put on me. Music was playing from them, and occasionally—the voice of the MRI operator. Think about it—in any headphones, there should be diaphragms and magnetic coils, yet inside an MRI coil, none of this can exist. I started to ponder, and if my implants are in order, maybe the headphones could be made from special materials like titanium. In general, I lay there and racked my brain. Eventually, I came to a solution, which turned out to be just that.
A thick hose stretched from the headphones to the machine, and that explained everything. The headphones are just cups with tubes stretching from the headphones to another room where the speakers are located. The sound travels through the tube via air—a very simple solution.
