You have a particle stoppage down stream or poor venting
Sink is not vented properly and the water from the p-trap under the sink COULD be sucked out by the hydrostatic pressure from the toilet flushing.
examples of internal noise.thermal noise,short noise,i/f noise
It makes noise because it's sucking the water back in to stop letting the water escape.
Noise immunity is the ability of a system to perform even when there is noise present. The higher the level of noise a system can still operate under, the higher the noise immunity.

Low coolant and air in the heater core.
Check your coolant level. The gurgling is often a sign that the coolant is level is too low.
Overheating or air trapped in cooling system.
The gurgling sound is caused by pressure in the engine coolant system(antifreeze) slowly releasing into the coolant overflow resevoir. Typically a faulty thermostat causes this sound.
Sounds like one of the fan blades are loose, or bent or out of balance. By saying whopping noise points to a problem with uneven air currents.
You either have a corroded or loose battery cable connection at the battery, a defective or drained battery, defective starter relay or starter.
