174 Hz is a frequency that is sometimes associated with the Earth in some alternative healing practices and spiritual traditions.
According to some sources, 174 Hz is said to be the frequency of the Earth's natural vibration or resonance, also known as the Schumann Resonance, which is the frequency of the electromagnetic field that surrounds the Earth.
Some proponents of sound healing and meditation suggest that listening to music or tones played at 174 Hz can help to promote feelings of grounding and connection to the Earth, and can help to reduce feelings of anxiety and stress.
Additionally, some proponents of sound healing suggest that 174 Hz can help to promote physical healing by reducing inflammation and promoting overall wellbeing.
