High pitched sound

I JUST got my new 2013 Prius Two and didn't notice this sound until driving home. It's so painful and stressful that it makes me not want the car at all and I feel totally screwed. I'm prone to migraines and this feels like it could cause one easily.

Here's a description that I found on another thread from A COUPLE YEARS AGO, and it suggests that the source may be the inverter. Since he references the flyback frequency from TV sets I know he's taking about exactly what I'm hearing. I can hear this and it's not healthy for me. Not sure what to do.

"the noise comes from the inverter, which uses high frequencies for converting electrical currents. Some people are much more sensitive to high frequency sound, which may account for why some people hear it and others don't.
At one time I could hear the flyback frequency from TV sets, and the high pitched whine from ultrasonic cleaners and some older security systems."

It's very disturbing that this issue has persisted for years without resolution. Not good.

Oh and I apparently can't include the direct link because I'm a new member, but string this together. Replace _ with / and remove spaces.

You're not alone. I just got my 2010 P2. When I test drove it out was snowing and slushy out, the sounds must have been muffled. The next time I drove it with the windows down it was nearly unbearable. I tried turning on the radio only to discover that my antenna was missing so no radio. Hopefully I can have that repaired along with the other issue I'm having. I purposely bought a Prius to have a quiet car since engine sounds and high frequency noises bother me. Ugh.

 

weird, i've never heard it in 3 pri over 14 years. i wonder if my dog whistle hearing is shot?
