Most likely due to hard water inside of the unit. Or possibley the h2o pressure going thru the valve.

Why does the toilet make a loud high pitched whistling noise for about 30 to 60 seconds after it is flushed?
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.
What is the humming noise within the toilet system?
Bad fil valve
What if your toilet makes a noise out of no were?
Your ballcock is comming on -- replace tank ball or sometimes you have to change out flush valve -- but change tank ball first and see if that will do it You hardly ever have to change flush valve -- Your ballcock is what lets water come into your tank
How do you stop the toilet tank from filling with water?
There should be shut off valve called an angle stop towards the floor on the left side of your toilet. If you shut this valve by turning it clockwise this will stop the feed of water to the tank of your toilet.A:Your float valve may be defective or worn out
What causes toilets to whistle when flushed?
My experience is when you flush the toilet, the fill valve opens and starts re filling the tank......sometimes if the water pressure is too high, it will "whistle". Close your fill valve until it stops whistling.....usually this slight adjustment will stop it from making that annoying noise
Why is my Toilet tank not filling?
First check to see if the valve for the water supply is turned on. If that isn't the problem you may need to replace the tank water valve, they do wear out and are not that expensive or difficult to replace.
What causes toilet tank to stop filling up with water?
The fill valve (ball valve UK) is siezed or clogged. As the water level rises, the float-ball rises and closes the valve when the water reaches the proper level.
When I turned on valve to toilet after being off for a while no water is filling the tank?
Make sure your main water is turned on by turning on another sink or bath and if it is then turn your toilet valve off and on a couple times and see if any water comes out in your tank. If still no water is filling the tank then shut off the valve and take the supply tube off the valve and turn the valve on slowly to see if you have any water comming out. If still no water then your valve is plugged or your pipe to the valve is plugged which then you would need to clean out your valve or lines with the whole house water shut off. Sometimes I have seen that the plug is in between the valve an supply pipe connection and as soon i take the supply pipe off and turn on the valve it works just fine even when I put the supply pipe back to the toilet. I don't think it would be in your fill valve in your toilet tank unless you have pressure assist tanks and with them all you need to do is take out the screen inside them.
When the toilets are flushed we hear a high pitched noise until the tank fills what would cause this?
Excessive velocity (FPS) on every toilet there is a globe pattern valve to THROTTLE to slow the volume and get rid of the noise
What causes valve noise on startup?
are you sure is a valve noise?? or is a piston slap?
What causes household plumbing to 'groan' when the toilet is flushed?
If this noise occurs after shutting off a fixture (e.g., shower or sink), I'd pop the lid on the toilet tank and check there. Sometimes, this type of noise occurs when water pressure is reduced somewhere else, causing the fill valve to open slightly and howl like a foghorn. So, after shutting off the water and hearing the noise, pull up on the toilet tank float to see if it stops. If it does, replacing the fill valve will fix it.if still problem persist call for plumbing repair service.
What would cause a sound like a fog horn after toilet flushing?
The only place that sound would come from would be a valve being closed. The only valve is the one in the tank. Replace the valve and this should eliminate that noise. To check this out try closing the water shut off part way and see if noise changes or goes away.
