How can loud noise affect balance and cause dizziness?

Loud noise can affect balance and cause dizziness because the inner ear houses both the cochlea, which is responsible for hearing, and the vestibular system, which controls equilibrium.12

While the cochlea uses hair cells to translate sound waves into nerve impulses, the vestibular system—comprising the vestibule and semicircular canals—uses similar hair cells to detect head position and motion. When an individual is exposed to high-level noise, the resulting acoustic trauma can disrupt these delicate structures. Because these systems are physically linked within the ear, intense acoustic energy can interfere with the vestibular system's ability to signal the body's orientation, leading to symptoms such as disorientation, motion sickness, and dizziness.12

It is important to protect your hearing and vestibular health by using appropriate ear protection devices when exposed to excessive noise levels, as damage to these sensory cells can be irreversible.2
