It's not a "false flushing." The system is designed to refill when the water in the tank drops below a certain point. This "flushiing" noise that you hear is probably the water running into the tank to refill it. There is probably a leak into the toilet, very small that it's almost unnoticeable, but still there. Check it out.
When a toilet makes noise when flushed, it is usually due to air being pushed through the pipes, causing vibrations and sounds. This can happen if there is a blockage in the pipes, a faulty valve, or air trapped in the system.
When a toilet makes a loud noise when flushed, it is usually due to a problem with the water pressure or the fill valve. This can cause the water to rush into the tank quickly, creating a loud noise. It is important to have a plumber inspect and repair the issue to prevent further damage.
This is normal.

The toilet may make a flushing sound when it hasn't been flushed due to a leak in the tank or a faulty flapper valve, causing water to flow into the bowl and create the sound.
The toilet may randomly make noise due to a faulty flapper valve, a loose fill valve, or a problem with the water pressure in the pipes. These issues can cause the toilet to run intermittently, leading to noise.
ON the 2006 impala that whining noise is actually the electronics when you accelerate. Its more or less electronic pulses/signals My 06 Impala is the same.
if it sounds like a high pitched whining then it may just be your cool air intake
yes but why would you leave it loose?
Usually the water filling up the flush valve in the tank. If it's bugging you, you can change the flush valve to a new one.
A toilet might make a burping sound when flushing due to air that was trapped in the pipe. Sometimes giving the toilet a quick plunge will prevent this.
this is normal and nothing to worry about. Almost all vehicles make a whining noise in reverse Ford Mondeo's sound the same reversing as they do going forwards no whining also VW Passatt i think the Golf's are the same also maybe modern technology has improved this. probably bad enough listening to your wife whining you can do without your car doing it.
