Starting at about 40 mph, a high-pitched noise starts and increases in volume with increased speed and is only heard through right side open window. No vibration. Pitch does not change, just volume. Does not sound like any pinion noise I have ever heard. I shimmed the door gaskets a year ago and got rid of the wind noise many Tacomas experience.
 
It’s always hard to diagnose with words. A video uploaded to YouTube and posted always helps. More info could be helpful.
Year, mileage and maintenance done is always helpful.
Could be a brake caliper sticking.
Could be a wheel bearing.
Could be this

I did some more research. The front hood gaskets compress over time and can make a whistling sound. I slid a vacuum hose through the ends of the 3 gaskets cut to length and the noise went away. Noise is better described as a whistle, not a whine.
