Sound Healing & Hypnotherapy
for Executives, Luxury Hotels & Global Brands
What is a Sound Bath?
A sound bath is an immersive sound experience – it is called a “bath” because the sound waves wash over you as you relax and enjoy the melodic journey. The harmonics and frequencies effortlessly lull your mind into a deep meditative state, while the healing vibrations revitalize your body and help release tension.
A sound bath is more than just a relaxing experience—it actively shifts your nervous system into a parasympathetic state, also known as the "rest and digest" mode. In our daily lives, stress often keeps us locked in the sympathetic nervous system, triggering the body’s fight-or-flight response. The sustained frequencies and rhythmic vibrations of a sound bath help lower cortisol levels, slow the heart rate, and regulate breathing, signaling the body that it is safe to relax and restore.
At the same time, the brain naturally begins to shift into theta wave activity, a state associated with deep meditation, subconscious reprogramming, and heightened creativity. Theta waves occur during the moments between wakefulness and sleep—the same brain state accessed in hypnosis and lucid sleep, where the subconscious mind becomes highly receptive. As the sound frequencies entrain the brain, they encourage mental clarity, emotional release, and a profound sense of inner calm. This combination of neurological and physiological relaxation is what makes sound healing so effective in reducing stress, improving sleep, and supporting overall well-being.

The Altha Mission
To motivate, enlighten, & inspire companies and individuals to prioritize well-being through the transformative power of sound medicine.
How Altha Started
Letizia Silvestri is the founder of ALTHA and one of the world's leading practitioners of sound healing and clinical hypnotherapy. After 18 years in luxury experiential marketing — working with McLaren, Lamborghini, Aston Martin, Bugatti, Rolls-Royce, and Pagani — she left at the peak of her career to heal herself from Hashimoto's disease through sound and hypnosis.
During the pandemic, Letizia deepened her practice, guided by an unexpected teacher—her rescue dog, Zen. Suffering from severe anxiety, Zen responded immediately to the soothing frequencies of sound healing. As his nervous system recalibrated, Letizia witnessed a parallel shift within herself. Her autoimmune disease disappeared, affirming the power of vibrational healing and subconscious reprogramming. This experience sparked the creation of Altha, a wellness platform designed to make the science-backed benefits of sound healing and hypnotherapy accessible to all.
Today, Letizia is a board-certified clinical hypnotherapist, sound healer and a SOMA Breathwork facilitator, leading bespoke hypno-sound baths at luxury hotels, retreats, and corporate wellness experiences worldwide. Her work has been featured in Forbes and trusted by brands such as Ferrari, Google, Gucci, Mastercard, and Six Senses. Through immersive, results-driven wellness experiences, she empowers individuals to reduce stress, enhance well-being, and unlock their innate healing potential. Her work has been recognized globally — she is a TedX speaker and has appeared in Forbes, Condé Nast Traveller, Marie Claire, and Women's Health, among others.
Altha is more than a brand—it’s a movement toward modern, science-backed healing through sound and hypnosis. Whether in a private session, a corporate retreat, or an exclusive wellness event, Letizia’s mission remains the same: to guide others in creating balance, inner peace, and lasting transformation.
