You have your reasons. But as soon as you get that window down an inch, you regret it. Because of that sound. It varies from car to car, and tends to be worse when it's one of the rear windows opened, but it happens to some degree on almost all newer cars. It's halfway between a sound and a rhythmic pulsating of pressure. An unending thrum thrum thrum thrum that, for most of us, drives you crazy.
Sure, opening the window more or sometimes changing your speed up or down will get rid of the offending pulsations, but the question remains: why does this happen? This seems like one of those things that smug know-it-all science has the answer to. Stephen Granade, who is on a first-name basis with science, to explain what's going on. That "whum whum WHUM WHUM" noise happens because the wind passing over the small window opening is like a bored drunk blowing over the neck of an empty beer bottle.
Air passing over an opening forms tiny tornadoes as it moves past the front edge of that opening. When those tornadoes, or vortices, reach the opening's back edge, they make a wave of pressure that pushes air into and out of the car. Since sound is nothing more than waves of pressure, this makes noise. If you're driving slowly the effect's not too bad, but if you drive fast enough, you reach a resonant point. Imagine I stand by your open car window and use my science powers to push on the air inside the car, compressing it a bit.
The car air then springs back out, then back in, then back out, then back in. With each cycle of moving out and in, the amount of air movement gets smaller until it completely dies away. This causes the popping sound you hear. The spring requires lubrication with motor oil and should be wiped clean using a dry cloth.
The torsion springs could also cause your garage door to come crashing down to the ground when you close it.
If you notice this happening, the torsion springs may be loose. Since torsion springs function under extreme tension, repairs or replacements, contact your local garage door technician to fix any loose or broken torsion springs right away. If your garage door appears to be functioning properly, you can try these additional methods to prevent garage door noise. Adding rubber to specific garage door components can help absorb vibrations and cushion loud noises. You can place a rubber pad between the garage door opener and the ceiling mount for a snug fit that eliminates rattling.
If the nuts and bolts clatter when they come loose, consider replacing metal washers with rubber varieties. If you look at the bottom of your garage door, you should find rubber weatherstripping along the edge. When your garage door closes, this piece seals the bottom to insulate your garage and keep insects and harsh weather out. It can also cushion the bottom of your garage door to prevent it from hitting the cement and making a loud sound.
Some rollers can cause more noise than others. A garage door can weigh several hundred pounds and place a lot of pressure on the hardware that raises it up and down.
The extreme tension can cause friction, so these parts require lubrication to keep everything running smoothly. If the lubrication dries up, these parts can grind against and stick to one another, causing excess vibrations.
Keeping everything greased will prevent rattling and other loud sounds. After resolving the noise, be proactive and continue lubricating regularly to prevent the sound from coming back. A good rule of thumb is to lubricate the bearings, rollers and hinges at least once a year.
Be sure to choose a lubricant that is safe for metal, like 10W motor oil. You can also look for silicone sprays or white lithium grease. An aerosol spray works well to maintain tiny moving parts. Apply the lubricant and wipe any excess off with a cloth. Proper garage door maintenance is essential to keep your door operating correctly and safely.

My garage door has been making a very strange sound lately. I think it would be a good idea to look for a repair company. The door makes a banging noise when opening so I go inside and click the opener.
The noise is from the top center of the door. I closed the door and re-opened it. The noise now comes from the upper right of the door. The door is only 18 years old and only used 8 or 10 times a day.
Time to call the installer? It makes sense that this would produce rubbing noises, as you mentioned. Published by: Michele Godden.

The clacks may indicate low power steering fluid or damage to a component in the steering column. These issues tend to progress over time, making the vehicle harder to maneuver as the problem develops. Some engine noises sound like they originate from the hood itself rather than what lies beneath it.
You may hear clunking or banging that sounds like someone keeping time by tapping on your hood. Clunking that happens in a rhythm can signal an issue with the pistons or connecting rods in your engine.
Ideally, your brakes should be virtually silent when you come to a normal, complete stop. Any brake noise should be investigated by a professional.
Once this level of damage occurs, your brake system may become unsafe and unpredictable. Not all clicking when you turn comes directly from the steering wheel. Popping and clicking noises may also seem to come from one or both of the front wheels. Generally, this type of popping will stop when you start driving straight again. The noise most likely indicates that you have a damaged constant velocity, or CV, joint in the front axle. Many automotive noises are reminiscent of another sound.
