Constant ringing, buzzing, whistling, hissing sounds in the ears can point to a common condition called Tinnitus. Besides soft-to-loud ringing in the ears, the most common form of Tinnitus produces soft-to-loud humming or rushing-water sounds.Objective Tinnitus is very rare and produces noises heard not only by the affected individual, but by others as well.
