Testing for infrasound or harmful subsonic sound at home can be challenging without specialized equipment. Infrasound refers to sound waves with frequencies below the lower limit of human audibility, typically below 20 Hz. To properly measure and analyze infrasound, professional-grade equipment, such as a specialized microphone or a dedicated infrasound detector, is necessary.
If you suspect that infrasound or harmful subsonic sound is affecting you and causing symptoms such as headaches, it is important to consider other possible causes as well. Headaches can have various origins, including stress, fatigue, dehydration, or other health conditions. It is advisable to consult with a medical professional to evaluate and diagnose your symptoms properly.
If you still want to investigate the sound in your environment, you can take the following steps:
Document your observations: Keep a log of the times, durations, and any specific details about when you experience the symptoms. Note any patterns or correlations between the symptoms and specific times or activities.
Evaluate other potential sources: Consider other factors in your environment that could contribute to your symptoms. These may include exposure to strong odors, poor ventilation, noise from other sources, or changes in your daily routine.
Noise monitoring apps: Some smartphone apps claim to measure infrasound or low-frequency noise. While they may provide an estimate, their accuracy and sensitivity can vary, and they may not be suitable for precise measurements. Nevertheless, using such apps could help provide a rough indication of the noise levels in your environment.
Seek professional help: If you remain concerned about the sound and its potential effects, consider consulting with a professional acoustician or an environmental health expert. They can assess your situation, conduct proper measurements, and provide expert advice or recommendations.
Remember that infrasound from common sources, such as household appliances, ventilation systems, or even natural phenomena like wind or ocean waves, is typically not harmful. It's important to approach the situation with an open mind and consider all potential causes before concluding that infrasound is the sole or primary source of your symptoms.
