Why Sound Healing

Sound healing is one of the most transformative modalities available today, ancient in wisdom and backed by modern science. Through frequency and vibration, it works directly with the nervous system, dissolving stress, unlocking deep relaxation, and creating powerful emotional and energetic shifts.

Research published in the Journal of Evidence‑Based Integrative Medicine shows that singing bowl meditation can significantly reduce stress, anxiety, anger, fatigue while increasing spiritual well‑being. Sound also influences brainwave activity, guiding the mind into restorative states that support clarity, healing, and release.

I created The Mastery of Sound to teach the techniques, principles, and energetic foundations that have shaped my own practice, so you can confidently facilitate profound, life‑changing experiences for others.

This 3‑month virtual training immersion refines your technique and expands your capacity to facilitate powerful, transformative sound healing sessions. Whether you’re a beginner or an experienced healer, you’ll deepen your understanding, refine your technique, and expand your capacity to support others. Join a community committed to transformation and step into the next evolution of your healing work

Meet your mentor

I’m a Master Sound Healer, Reiki Master, and Breathwork Practitioner with over a decade of experience across the wellness industry — from corporate wellness and retreats to 1:1 healings and global brand events. I’ve trained extensively, including the Sound Healers Academy in California and a year‑long advanced mentorship with TSHA, and my sound work has been trusted by clients ranging from intimate sessions to brands such as Google, Samsung and L’Occitane.

My approach blends science and spirituality, using sound to support deep cellular healing, neuroplasticity, and nervous system regulation. With a BSc in Economics, I also bring a grounded business perspective to this training, helping you build a sustainable, aligned sound healing practice that feels true to you. I created this training to share the tools that changed my life, and to help others step into their own healing gifts with confidence, direction and clarity.

Student Testimonials 2026

  • “Attending this course with Audrey O’Connor has been so much more than just training it has truly been the beginning of a journey.

    When I started, I didn’t really know where this path would lead me. Now I can clearly feel that becoming a sound healer is something that made my soul come alive… something that was calling me, even before I fully understood it.

    In many ways, my journey began two and a half years ago, when I first arrived in Dublin and attended my very first crystal bowl sound bath with Audrey. Something shifted in me that day and this course feels like a continuation of that first moment.

    Concha Julian - The Mastery of Sound 2026

  • Cont. - “The training has been intense, but throughout the entire process Audrey has been there for us supporting, encouraging, and guiding us with so much care and dedication. We have learned so much, not only about crystal bowls and sound, but also about ourselves.

    This has been a deeply transformative experience on a personal level. There has been so much kindness, generosity, and heartfelt sharing. And now, beyond all the knowledge we’ve received, there is also a beautiful process of integration beginning.

    I cannot express enough how grateful I am for everything this journey has given me.

    Thank you, Audrey, for opening this door

    Concha Julian - The Mastery of Sound 2026

  • “Audrey has been an incredible Instructor and Mentor throughout my Sound Therapy journey.

    Through this course my belief in myself and my abilities has blossomed. I truly feel Audrey came into my life at exactly the right time she is an angel sent to guide, support and inspire me on this path.”

    Aideen Shelley - The Mastery of Sound Graduate 2026

  • “My training with Audrey has exceeded all of my expectations. She keeps the group intentionally small, which makes the entire journey feel deeply personal and intimate.

    Through this training, I have developed skills both personally and professionally that I know will stay with me for a lifetime.

    Audrey is such a caring and generous person, always giving so much of her time and support. I truly couldn’t recommend this training enough, and I am so grateful I chose to go on this journey. Thank you, Audrey”

    Katie Burke - Mastery of Sound Graduate 2026

  • I absolutely adored doing The Mastery of Sound course with Audrey O Connor. I am so glad that I did the course with her as I feel very confident in my abilities going forward. Audrey is a wonderful teacher. She is consistently supportive and present during the whole course. She nurtures and cares for everyone who does her course. It starts from the very beginning with the Discovery Call. You know from that call if this course is going to be for you. I loved the structure, the reading lists, the online portal, the weekly zoom meetings. 

    Audrey is a fountain of information and wisdom. I really loved the way she was able to help me discover what my skills were and what way I would be able to structure a Sound Bath myself. I honestly absolutely loved doing this course and know it was the best course that I could have chosen. Go raibh míle míle maith agat ó bhun mo chroí.

  • “From the moment I had my first call with Audrey I felt inspired. During the training I have not only learned to play the bowls, I have also learned that I am capable of everything I aspire to and more, because all that is available to me when I do it intentionally.

    I will finish the training with 6 new friends, women from whom I have learned and from whom I will always feel inspired. Thank you Audrey for making this possible! Love, Paola”
