This probably won't cause hearing loss. If you are worried, you should talk to our doctor or have your hearing tested.
A malfunctioning water heater can cause hot and cold water to surge through the shower heat. A faulty water pump can also cause this problem.
you have trash in your line take the shower head off and remove trash or possibly in water valve at shower
It will not work to smoke while in shower as the water will turn off the cigarette or cigar.
Seats in the main valve body are leaking by, allowing water to go to the shower head.
If you have a new pressurised water system there is a possibility that the added water pressure could cause a leak.
A dirty or clogged screen can cause the low water presser remove shower head and clean. If not it could be calcium deposits built up on shower head if so soak shower head in a cleaning solution for several hours if that dose not work buy a new shower head. (note some shower heads have a low flow re-stricter in some cases you can remove this and get more water pressure)
the shower and bath water comes from two different places so their is two different pipes. Get the shower pipe checked out by a plummer and they cause fix the pipe.
Bad shower valve.
Chlorine shower filters are used for to eliminate the chloroform in the water, to take away the harsh, drying effects to human hair. The chlorine in the water can cause rashes to skins.
Water entering the shower has no sperm. Water leaving the shower might, depending on who was there last.
My first thought is a leaky hot water line.
because people are wasting water and there is none left for the everglades also cause of people leaving the water on or taking a long shower
