What causes persistent tinnitus?

The ears play a vital role in daily life; however, tinnitus—ringing or buzzing in the ears—can significantly impair one’s ability to hear sounds clearly. This not only affects routine work performance but also hinders normal communication with others. So, what causes persistent tinnitus?

What Causes Persistent Tinnitus?

Persistent tinnitus may stem from systemic diseases, inappropriate medication use, or ear-related disorders. For instance, certain systemic conditions—such as hypertension or cerebral hypoperfusion—can trigger tinnitus. Generally, individuals aged 60 and older exhibit the highest incidence of tinnitus, primarily because the auditory nervous system gradually deteriorates with age. Moreover, underlying illnesses further increase susceptibility to tinnitus. Overuse or misuse of ototoxic medications—drugs harmful to the ear—can also lead to hearing loss or tinnitus. Therefore, patients are advised against self-medicating without professional guidance. Untreated ear disorders—including outer ear infections and acute or chronic otitis media—may likewise progress to tinnitus.

In recent years, excessive stress has become an increasingly common cause of tinnitus. High levels of psychological stress and tension often result in high-frequency tinnitus—commonly described as a “cricket-like” ringing sound. Tinnitus frequently occurs in individuals with emotional instability; those suffering from anxiety or depression are also particularly prone to it. The human ear can tolerate sound intensities up to approximately 90 decibels (dB); beyond this threshold, damage may occur without immediate awareness. Due to the inner ear’s fragility, prolonged or irregular exposure to intense, noisy stimuli can inflict substantial and irreversible harm to hearing.

If you experience tinnitus, seek prompt medical evaluation to identify the underlying cause and initiate appropriate treatment. We hope this information proves helpful.
