Have spent hours following threads on B6G about quieting down my hard top, and not a one made any measurable difference. Finally, today I made a tiny change; added some 3M molding adhesive to the right T-top’s middle seal in front, to stick the rubber down a little more where it meets the left T-top and the windshield. Finally measured a db less of wind noise. Doesn’t sound like much but since my ears are close to that area, it made a noticeable difference.

You're forgetting that decibles are actually measured in a logarithmic scale. That 1dB difference is actually big.

For example, an increase of 3dB means you've doubled the sound energy.
