Decibullz Custom Molded High Fidelity Earplugs | Nervous System Regulation

• Nerve Dysregulation

Individuals with long COVID often experience heightened sound sensitivity (hyperacusis) and difficulty processing noise in busy environments. Decibullz Custom Molded Earplugs reduce ambient noise without distorting sound quality, allowing users to engage in conversations and activities comfortably. By reducing auditory overload, these earplugs may help improve focus, reduce stress, and enhance overall comfort in noisy settings — common challenges for long COVID sufferers. Scientific Explanation on How the Product Works:
Noise sensitivity (hyperacusis) is a common symptom in long COVID, stemming from dysfunction in the auditory processing pathways and the autonomic nervous system. Research suggests that the overstimulation of the auditory nerve due to increased sensitivity to sound can trigger a heightened stress response, leading to increased fatigue, brain fog, headaches, and nervous system dysregulation.

Decibullz earplugs work by reducing overall noise exposure while maintaining sound clarity. By attenuating sound evenly across all frequencies, they help prevent overstimulation of the auditory nerve, reducing the stress load on the brain. Lowering sensory input in this way allows the brain and nervous system to remain in a calmer state, potentially improving cognitive function, reducing headaches, and improving overall mood.

Additionally, balanced noise reduction can improve the brain’s ability to filter and process sounds, reducing mental fatigue and enhancing focus. Research has shown that limiting exposure to high-frequency noise can also help regulate the parasympathetic nervous system, promoting relaxation and better sleep — factors that are crucial for recovery in long COVID patients. By protecting against sensory overload, Decibullz earplugs may contribute to improved cognitive clarity, reduced fatigue, and enhanced emotional regulation in individuals with long COVID.
