How is the tonal subtype of tinnitus best described?

The tonal subtype of tinnitus is characterized by a sound that is usually constant and can manifest as a ringing or buzzing noise that persists over time. This form of tinnitus does not vary in intensity or frequency and is typically experienced as a steady tone, setting it apart from other types that may fluctuate or occur occasionally. Continuous tinnitus often disrupts daily living, as the constant presence of sound can be challenging for those affected.

In contrast, the other options suggest more variability. Episodic tinnitus implies that the sound comes and goes, while intermittent tinnitus suggests it may have periods of onset and resolution. Pulsatile tinnitus is a specific type that is linked to a rhythmic sound in sync with the heartbeat, rather than the consistent noise pattern found in the tonal subtype. Therefore, recognizing tonal tinnitus as continuous allows for a clearer understanding of how it affects individuals and distinguishes it within the broader spectrum of tinnitus experiences.
