What Is Tinnitus?
Tinnitus is noise that originates within the ear rather than from the outside environment. This may affect one or both ears.
The sounds have been described variously as a "ringing" sound, a "buzzing" sound, a "humming noise, "like running water", a "whistling" sound or like the "sound from a seashell held close to the ear."
here are several common types of tinnitus:
* Tonal tinnitus is often called "ringing in the ears." This type of tinnitus produces a continuous sound, like a single note playing over and over.
* Pulsatile tinnitus, in which the tinnitus sounds are intermittent, continuous, or pulsating in time with the heartbeat.
* Tinnitus in which the sound is a ringing, buzzing, roaring, whistling, or hissing noise.
* Less common tinnitus, in which the sounds are described as beeping, Morse code type of signals, or even a musical notes.
* Less common still is tinnitus experienced as several different types of noises at the same time.
In a rare, unusual type of tinnitus, known as "objective tinnitus," the noise is heard not only by the affected individual but also by others.

This happened to me while I was in the hospital. I vaguely remember the morse code noises seemed to be coming from the air conditioning vents rattling. Good luck solving the mystery.
