Clinical Causes: Natural sources like thunderstorms, volcanic activity, and seismic events. Industrial environments with machinery generating infrasound emissions. Wind turbines and other renewable energy installations producing low-frequency noise. Prolonged exposure in enclosed spaces with inadequate sound insulation. Certain musical instruments or loudspeaker systems operating at infrasonic frequencies.

Key Symptoms: A sensation of spinning or dizziness that worsens with movement. Feeling of imbalance or unsteadiness. Nausea or vomiting in some cases. Sensory symptoms such as ringing in the ears or a feeling of pressure in the head. Difficulty concentrating or feeling of disorientation.

Diagnosis Path: Diagnosis typically involves a thorough clinical evaluation, including assessment of exposure history to possible infrasound sources. Healthcare providers may perform balance tests, hearing assessments, and vestibular function tests. Since infrasound is inaudible, identifying environmental sources is crucial for diagnosis. Additional diagnostic procedures such as MRI may be used to rule out other causes of vertigo or dizziness.

Treatment Protocols: Management of vertigo from infrasound primarily focuses on reducing exposure to the offending sound sources. Strategies may include relocating away from infrasound-emitting environments, improving sound insulation, and using protective devices. Symptomatic treatment with medications like vestibular suppressants can provide relief, but addressing environmental factors is essential for long-term resolution. Vestibular rehabilitation therapy might be recommended to improve balance and reduce dizziness.
