Frequency Calculator: Explore Meditation Sound Frequencies

What This Tool Is For

This calculator is a reference for the tones, notes, and associations that circulate in meditation and sound-healing communities. Choosing a frequency is a way to pick a listening session that matches the mood you want — much like choosing music by key or tempo. It is designed for personal reflection and mindful listening rather than medical assessment or individualized health advice.

A note on expectations: the associations below come from tradition and popular practice. Science is only beginning to study what these traditions have long practised, and individual experiences vary. Enjoy the tones you like, at a comfortable volume, and treat any outcome as personal exploration.

Brainwave Frequency Ranges

The brain produces electrical activity across a range of frequencies, each accompanying different states. These labels describe the activity, not what a track will do to you:

Delta (0.5-4 Hz): The slow activity typical of deep, dreamless sleep.
Theta (4-8 Hz): Common during drowsiness, light sleep, and drifting attention.
Alpha (8-12 Hz): Seen during relaxed wakefulness with closed eyes.
Beta (12-30 Hz): Typical of active thinking and everyday focus.
Gamma (30-100 Hz): Peak cognitive performance, heightened awareness, and moments of insight. Associated with advanced meditation states.

The Solfeggio Frequencies

The Solfeggio frequencies are a set of ancient tones used in sacred music across multiple traditions. Each frequency carries specific healing associations that have been recognised for centuries and are now being investigated by modern researchers:

174 Hz: Pain relief, grounding, and physical healing. Associated with the Root Chakra.
285 Hz: Tissue repair, energy restoration, and cellular healing. Supports the body's natural regenerative processes.
396 Hz: Liberation from fear and guilt, courage, and confidence. Associated with the Solar Plexus Chakra.
417 Hz: Facilitating change, clearing negative patterns, and cellular transformation.
528 Hz: Known as the "Love Frequency" or "Miracle Tone." Associated with DNA repair, love, and profound healing.
639 Hz: Harmonising relationships, enhancing communication, and cultivating connection. Associated with the Heart Chakra.
741 Hz: Awakening intuition, problem-solving, and expanding consciousness. Associated with the Third Eye Chakra.
852 Hz: Returning to spiritual order, awakening inner strength, and spiritual insight.
963 Hz: Pineal gland activation, divine connection, and cosmic consciousness. Associated with the Crown Chakra.

432 Hz vs 440 Hz Tuning

Standard modern music is tuned to 440 Hz (concert pitch). Many sound healers and musicians advocate for 432 Hz tuning, which they describe as more harmonically aligned with natural mathematical ratios and the resonant frequencies of the natural world. While the scientific evidence for this claim is still emerging, many listeners report that 432 Hz music feels warmer, more relaxing, and more conducive to meditation.
