[Information] Basic Knowledge of Sound <Sources of Low-Frequency Noise Hidden in Daily Life>

First, investigate the source and take measures early! Introducing the sources of low-frequency sounds that lurk in daily life!

This document introduces the basic knowledge of sound. It includes sources of low-frequency noise that lurk in daily life, such as "sources hidden within the home," "low-frequency noise from outdoor units," and "low-frequency noise from nearby facilities." Unlike regular noise, low-frequency sounds often go unnoticed when one is simply present in the area, making it difficult to predict their impact on oneself. If insomnia or health issues are suspected to be influenced by low-frequency noise, rather than just enduring it, it is advisable to first investigate the sources and consider possible solutions before the situation worsens.
