I've been doing a little research since the dealership told me everything was fine. I've found my way to an interesting notion.
I apparently have a perception, real or imagined, that the vehicle is swaying. I did not notice this until we took it on the first long trip.
When we got home last night I commented that I felt dizzy after being in the car all day. Figured it was either allergies or the motion of the vehicle that I think has an issue.
What else could it be? Is it really all in my head? Maybe so.
The new Equinox uses noise cancelation to make the cabin quiet. So I searched for noise cancelation and dizziness and found this:
According to a recent report in the Wall Street Journal Bose's QC3 headphones could very well be bad for you.
“I was recently given a pair of the Bose QC3 headphones with active noise canceling, and have felt queasy every time I put them on,” writes one dejected reader.
“I had to take them off and lie down at one point, and ended up throwing up later that night and was unable to eat more than apple sauce the next day. As crazy as it sounds, did the headphones cause my discomfort?”
Negating unwanted noise
According to the WSJ’s health experts it is possible, because: “Acoustic Noise Cancelling headphones work by electronically determining the difference between wanted and unwanted sounds, and creating a correction signal that acts to negate the unwanted noise.”
Techradar contacted Bose in the UK today for comment on this, but nothing was forthcoming at the time of going to press.
Disequilibrium and dizziness
The WSJ also cites Sarah Stackpole, a New York ear, nose and throat doctor, who “speculates that the sound waves that cancel each other out may still transmit enough very low frequency vibrations to stimulate the balance receptors that are connected to the hearing hair cells in the inner ear… The disequilibrium that some people may feel from this is made worse because the vibrations falsely signal that the head is moving, but the eyes report that the head is stationary. Those mixed signals make the headphone wearer feel dizzy.”
