What is NOT a symptom of acoustic trauma?

Acoustic trauma refers to hearing damage resulting from exposure to loud sounds, which can happen suddenly or accumulate over time. The symptoms typically associated with this type of trauma include hearing loss, tinnitus (a ringing or buzzing sensation in the ears), and sometimes vertigo due to the impact of sound on the inner ear structures.

Impaired vision, on the other hand, is not a recognized symptom of acoustic trauma. It primarily affects the auditory system, leading to auditory issues rather than visual impairments. Therefore, the correct answer highlights that impaired vision is unrelated to acoustic trauma, as the other symptoms listed directly relate to the effects of loud noises on hearing.
