Could be hydraulic shock (water hammer)
somehow you'll hear a windy noise in the water line
As far as I know, its usually a loose washer in the piping somwhere or a mishapen one. An old plumber told me if you hammer the washer on flat surface, that can correct it. Basically as you run the water it resonates creating the noise. The washer is probably in the faucet btw. Like I said I'm no expert just saying from experience.

A gurgling noise in a coffee maker could be caused by air bubbles trapped in the water reservoir, a clogged water line, or a malfunctioning pump.
bunn has several but they are pricy
If the drain line from the ac unit is tied into the sink drain line, the trap leaving the ac unit has probably run dry. Fill the trap at the ac unit with a cup of water and it should stop the noise. Assuming a proper install, kinda hard guessing about it from here without seeing it.
intermodulation noise
Your Keurig may be making a loud noise when drawing water due to a clog in the water line, a malfunctioning pump, or air bubbles in the system. It is recommended to clean the machine and check for any blockages to resolve the issue.

To connect a faucet to a water supply line using an adapter, first, ensure the water supply is turned off. Then, attach the adapter to the water supply line and connect the faucet to the adapter using the appropriate fittings. Finally, turn on the water supply and check for any leaks.
