When the tensor tympani muscle experiences a spasm without the provocation of loud sounds, it's called the acoustic reflex, which is apart of a normal auditory system. [9] However, this reaction can be caused by general anxiety, or anxiety concerning the sudden onset of noises or ear pain, which can follow an acoustic incident.
A screening program focused on construction workers employed at US Department of Energy facilities found 58% with significant abnormal hearing loss due to noise exposures at work. [42] Occupational hearing loss is present in up to 33% of workers overall. [43] Occupational exposure to noise causes 16% of adult disabling hearing loss worldwide. [44]
Though the pathophysiology of tinnitus is not known, noise exposure can be a contributing factor, therefore tinnitus can be associated with hearing loss, generated by the cochlea and central nervous system (CNS). High frequency hearing loss causes a high pitched tinnitus and low frequency hearing loss causes a roaring tinnitus. [19] Noise ...
In many cases, worsening, high-pitched tinnitus and hearing loss are linked to damage from noise exposure over time and can hit suddenly or worsen gradually, per a 2016 study in Noise & Health.

Acoustic trauma can occur from a single, loud noise exposure or loud noise over a period of time. One sign of acoustic trauma is ringing in the ears and muffled hearing after a loud sound exposure.
A setback is a temporary exacerbation of symptoms, a worsening of the perception of loudness or pain from sound, often due to a particular noise exposure. [12] Setback prevention is an important focus among those affected. Efforts to avoid setbacks commonly include using hearing protection and avoiding loud noises. [17]
