In order for water to flow down a pipe, there must be a vent to allow the air to escape. Above a toilet, on the roof, there is usually a pipe or a vent hood, which is connected to the drain pipe. When the toilet is flushed, the sound of water draining can be heard issuing from this vent. In addition to the above answer, the air rushing through the water may be the cause of the gurgling sound, which is the air escaping through the vent to prevent the build up of air pressure inside your water system.
There is a blockage in the pipe between the two.
The float valve shutting off the water flow.
Excessive velocity (FPS) on every toilet there is a globe pattern valve to THROTTLE to slow the volume and get rid of the noise
A toilet may be making noise if parts are wearing out or a problem exists in the plumbing. It may be a good idea to contact a plumber to see if there is a bigger problem.

You are probably hearing the hot water hitting the cold pipe which causes expansion thus the pinging sound. Drain speed could probably be clogged vent stacks try cleaning them out.
You probably aren't getting a good seal around the flapper and every few seconds the tank has to fill up. This is usually caused by the chain that lifts the flapper is too long and gets caught under it when it tries to close. Simply shorten the chain.
Has your radiator been flushed and filled up with coolant lately, The Ac receiver/dryer, or compressor or condenser should be changes regularly, there should be clogged...
One of the supply lines has a hole or the faucet itself. You probably have seen the water by the time you get this. You probably have to shut the whole house off, most tubs don't have their own shut off valves.
