New to sound healing? Wondering which tuning fork is right for you?
We've answered the most common questions from our community of 10,000+ customers and practitioners worldwide with honesty, science, and clarity.
Module 1: How It Works
How do tuning forks actually work on the body?
Tuning forks create stable vibrations measured in Hertz (Hz). When placed on the skin, these vibrations travel through bone and tissue (bone conduction) to stimulate the vagus nerve. This physical process signals the nervous system to shift from a "fight-or-flight" stress response into a restorative, calm state. It is acoustic physics applied directly to human physiology.
What is "vibrational entrainment" and why does it matter?
Entrainment is the biological tendency for internal rhythms to synchronize with an external signal. When stressed, your body's rhythms become erratic. A tuning fork provides a steady, coherent reference tone that your nervous system naturally begins to follow, similar to a metronome steadying a beat. Consistent use strengthens this synchronization over time.
Is there scientific research supporting sound healing?
Yes. Vibroacoustic therapy is studied in clinical contexts. Research in the MDPI shows measurable reductions in cortisol, anxiety, and pain. Specifically, 128 Hz is used professionally for nerve conduction testing. Ovivra tools are designed as evidence-based wellness complements, not medical replacements.
Module 2: Choosing the Right Fork
I'm new to sound healing. Which tuning fork should I start with?
We recommend the 128 Hz weighted tuning fork for beginners. It provides immediate physical feedback through strong vibrations, making it easy to use correctly. For enhanced emotional balance, many users pair it with the 136.1 Hz (OM Tuner) to create a complete daily ritual kit.
What's the difference between weighted and unweighted tuning forks?
Weighted forks: Feature metal discs at the tips to increase vibration intensity. Best for direct contact on muscles, joints, and bones to relieve physical tension.
Unweighted forks: Vibrate faster and produce a cleaner audible tone. Best for meditation, mental clarity, and "space clearing" without physical body contact.

Solfeggio vs. Chakra tuning forks: What's the difference?
Solfeggio forks (174 Hz–963 Hz) focus on specific emotional or energetic states, such as 528 Hz for renewal. Chakra forks are calibrated to correspond to the body’s seven primary energy centers for localized balancing. Choose Solfeggio for emotional work and Chakra for energy alignment.
Which frequency is best for sleep and anxiety?
For sleep, the 136.1 Hz (OM Tuner) is the standard choice as it promotes a deep meditative state. For anxiety, the 528 Hz unweighted fork is used for emotional calming, while the 128 Hz weighted fork provides grounding through physical vibration.
Module 3: How to Use
How do I correctly activate a tuning fork?
Strike the upper one-third of the tines against a rubber mallet or hockey puck activator. Avoid hard surfaces like metal or wood, which can damage the calibration. A correct strike provides 20–30 seconds of effective vibration.
Where exactly do I place the tuning fork on my body?
For weighted forks, place the stem (the handle base) on the sternum (chest bone) for anxiety relief, the sacrum for grounding, or directly on tense muscle areas. Unweighted forks should be held 1–3 inches from the ears or moved through the air surrounding the body.
How often should I use my tuning fork?
Daily use is safe and recommended. （3-minute tuning fork ritual guidance audio）Most users feel relaxation within 1–3 minutes. We suggest a 3-minute morning ritual for a calm baseline and a 3-minute evening ritual to prepare for sleep. There are no chemical side effects or upper limits to use.
Module 4: Safety & Who It's For
Are tuning forks safe? Any contraindications?
Tuning forks are non-invasive and chemical-free. However, avoid direct placement near pacemakers, open wounds, blood clots, or areas of recent surgery. Pregnant individuals or those with diagnosed medical conditions should consult a healthcare provider before use.
Can children or sensitive individuals use them?
Yes. Children often respond well to shorter (1–2 minute) sessions. For highly sensitive individuals, we recommend starting with lower frequencies (128 Hz or 136.1 Hz) and using unweighted forks held near, rather than on, the body.
Module 5: Quality & Orders
Why do Ovivra tuning forks sustain longer than others?
Ovivra forks are forged from high-density, medical-grade alloy. Cheap alternatives often use soft aluminum that loses vibration in 5-8 seconds. Our alloy provides 20–30 seconds of stable sustain and maintains pitch accuracy over years of use.
What is your shipping and return policy?
We offer tracked worldwide shipping (5-14 business days depending on location) and a 30-day satisfaction policy. Every Ovivra order includes the precision-tuned fork, an activator mallet, a storage pouch, a cleaning cloth, and a digital Mastery Guide.
