EM interference produced by the S2000 Engine?????
This has to be a truly unique experience.
Yesterday, I'm going to pick up dinner in my S2000, with the top down, and my wife calls on my cell.
Now, I wear hearing aids, so to make sure I could hear over the wind noise, I switch my left hearing aid into T-Coil mode. A TeleCoil (aka t-coil) is a pretty ingenius device and in order to tell you the rest of the story, I first need to explain how it works:
Speakers work on the principle that a speaker cone moves air (makes noise), and an electromagnet (powered by the current from the amplifer) causes the speaker cone to move (and thus move the air).
Well, the T-coil is a magnetic pickup. Put it next to the speaker, and the magnetic waves from the speaker magnet will induce a current IN the hearing aid's t-coil (the same way a generator works -- it induces a current by running magnets along side of wires), the current can then translated back into the sound by the hearing aid.
It aint perfect sounding, and it's succeptible to all sorts of electro magnetic interference, but the noise around you will NOT matter one bit. I have happily carried on phone calls in the middle of a Dave And Buster's with this gadget (unable to hear anything else but my phone call in fact!).
That being said, I ended my phone call and continued to drive on...and found:
My T-Coil was picking up the engine! It made a noise like many types of interference it might pick up, but the frequency of the noise was DEFINTELY linked to how fast the engine was revving.
I've *never* had this experience in any other car, but I'm about to start experimenting....
Providing you more than you ever wanted to know about your car...
