    By the "vent" do you mean the aspirator? The quarter size speaker looking thing above your head in the head liner? Those do go bad. They are easy to pull apart, clean, and lube.

    Wind coming through a bad seal, maybe? That would explain the increase in volume/sound as you drive faster...

    try pulling of your wipers and bug shiled if you have one, sometimes those can mess with airflow and make odd noises.

    I have a bug shield and a similar noise. In my truck it sounds like it is at the top of the windshield on the passenger side. Similar sounds to when rain droplets fly off the hood and hit the windshield.

    I had to have my windshield resealed. I had a bad wind noise over 45mph

    I just noticed a similar noise this morning on my way to work. Almost sounded like radio static coming through the A pillar speakers but I turned the radio off noise persisted. Just installed a WeatherTech bug deflector a few days ago, wondering if that could be creating the noise...
