You need to define which water heater, and try to describe the noise please, otherwise nobody can guess at what the problem is with any degree of accuracy. Untill then, take no notice of answers to date.

Sounds like you have a faulty pressure relief valve that's leaking when the water is heating up. As long as it's not coming out fast or the water is causing damage, you don't really need to worry about it. That relief valve is there to prevent the water heater from overpressurizing and blowing up in case the heater gets stuck on. And, it shouldn't open at all during normal operation. However, over time, the springs in the valve that are supposed to release at high pressure get old and weak, resulting in some leakage. But, it's not really an operational problem.

If it is a "sizzling" sound, that is condensation that is dripping on the burner. Assuming it is a gas water heater. This is normal. But, if it is a "thumping" sound, that is caused by lime and scale build-ups that have air pockets in them, thus heating the water to steam, and then it "bubbles or thumps" in the water area. This is not a good sign.
The eater heater needs to be flushed out. If this is an older water heater, you will probably have to replace it soon, as it will eventually cause a leak in the bottom of the heater, due to rusting.

Could be as simple as contraction/expansion caused by cold water being added to a hot/warm tank. If it is a popping sound and a gas unit, it probably needs drained and flushed. Sediment builds up on the tank bottom and "boils" when the heat comes on. This wastes energy since the sediment needs to be heated before the heat gets to the water.

Because its clogged with sediment and there is insufficient volume available to heat the water evenly, so it 'bumps' and makes noises as it unevenly heats both the water and the sediment 'rocks'.

Expansion from heating up cold water and contraction from the cold water entering. Simple.

Water heater? so many kinds. Shower? electric or mixer? many kinds.

Take your time and think about the question, Be as technical as you can.
Your wasting your and our time with poor question!

.Could have limescale or other deposits building up inside. Possibly have an airlock.
It may require a service if not serviced within the last year.

Check the Pressure relief valve..

it is pumping more water back into it to heat! when you use the water it has to replenish the water in order to give you more hot water later. it is normal please don't worry!
