Tinnitus: Is It Caused by Long-Term Earplug Use? - Otolaryngology

Tinnitus, or ringing in the ears, can be a perplexing condition, and your experience with low-frequency buzzing sounds in your right ear while using earplugs is certainly noteworthy. While it is not uncommon for individuals to experience tinnitus, especially in quiet environments or after prolonged use of earplugs, the exact cause can vary significantly from person to person.

Long-term use of earplugs can potentially contribute to tinnitus for several reasons. Firstly, earplugs are designed to block out sound, which can lead to a heightened awareness of internal sounds, such as blood flow or muscle contractions, that might otherwise be masked by ambient noise. This phenomenon is sometimes referred to as "auditory deprivation," where the brain becomes more sensitive to sounds that are usually not perceived. Consequently, when you remove the earplugs, the external sounds can seem more pronounced, and the internal sounds may become more noticeable, leading to the perception of buzzing or ringing.

Additionally, the physical act of inserting earplugs can sometimes irritate the ear canal or the eardrum, leading to temporary changes in hearing or the sensation of fullness in the ear. This irritation can also trigger a response in the auditory system, resulting in tinnitus. However, since you mentioned that your hearing tests and auditory brainstem response tests were normal, it suggests that there is no significant underlying pathology affecting your hearing.

It is also important to consider other factors that can contribute to tinnitus, such as stress, fatigue, exposure to loud noises, or even changes in ear pressure. You noted that you experienced a popping sound in your ear while lying on your side, which could be related to changes in pressure within the ear or Eustachian tube dysfunction. This is generally not a cause for concern unless accompanied by pain, significant hearing loss, or other troubling symptoms.

Given that your symptoms appear to be linked to the use of earplugs, it may be beneficial to take breaks from using them, especially during sleep, to see if your symptoms improve. Additionally, practicing relaxation techniques and managing stress can also help alleviate tinnitus symptoms, as stress is known to exacerbate the condition.

If the buzzing persists or worsens, or if you experience any new symptoms, it would be prudent to consult with an ear, nose, and throat (ENT) specialist or an audiologist for further evaluation. They can provide a more comprehensive assessment and discuss potential treatment options, which may include sound therapy, cognitive behavioral therapy, or other interventions designed to help manage tinnitus.

In summary, while long-term use of earplugs can potentially contribute to the development of tinnitus, your situation seems to be relatively benign given the normal results from your hearing tests. Monitoring your symptoms and making adjustments to your earplug usage may help mitigate the buzzing sensation. Always prioritize your ear health and seek professional advice if you have concerns about persistent symptoms.
