Different Forms of Tinnitus


1. Subjective tinnitus has many forms and may be
regarded as a group of disorders rather than a single
disorder.
2. There are a few objective ways to distinguish between
the different forms of tinnitus.
3. Tinnitus has been classified subjectively according
to:
(a) Intensity: Often using a visual analog scale or
loudness matching.
(b) Character: High frequency (like crickets), low
frequency (rumbling), tonal, pulsatile, constant,
or intermittent.
(c) Other features such as the ability to modulate
the tinnitus by manipulating their jaw, moving
their eyes, or applying pressure on neck
regions.
(d) Whether referred to one ear, both ears, or perceived
as being inside the head.
4. Some diseases, such as Ménière’s disease, are
accompanied with tinnitus; such tinnitus may be
different from other forms of tinnitus.
5. Some forms of tinnitus are associated with affective
disorders such as depression or phonophobia.
6. Subjective tinnitus is often accompanied by abnormal
perception of sounds, known as hyperacusis
(lowered tolerance for sounds) or hypersensitivity
to sounds.
