Thomas Allen, Ph.D. is a psychologist who has been in private practice for more than 40 years and has spent over three decades exploring the relationship between sound, consciousness, healing, and spiritual development.
The Acoustical Pyramid grew out of Dr. Allen’s long-standing fascination with meditation, altered states of awareness, sacred sound, and the mysteries surrounding the pyramids of ancient Egypt. Through years of study, experimentation, reflection, and direct experience, he began developing immersive sound meditations inspired by the acoustics and symbolism associated with the pyramids of Giza.
Today, the Acoustical Pyramid represents the culmination of that work.
With a background grounded in psychology and decades of clinical experience, Dr. Allen became increasingly interested in the effects sound, vibration, and meditative states may have on emotional balance, consciousness, and personal transformation.
Over the years, sound healing and frequency-based meditation practices have become increasingly present in both spiritual and wellness communities. The Acoustical Pyramid explores these ideas through immersive sound environments designed to encourage relaxation, introspection, stillness, and expanded awareness.
Much of Dr. Allen’s work focused on the acoustic properties of the King’s Chamber within the Great Pyramid of Giza. Using the chamber’s dimensions and the placement of the sarcophagus, he began experimenting with standing-wave simulations intended to recreate aspects of the chamber’s resonance and energetic atmosphere.
These explorations eventually expanded into recordings captured within several pyramids themselves, including Menkaure, Khafre, the Red Pyramid, and the Great Pyramid of Khufu.
Dr. Allen’s work has also been shaped by decades of personal exploration into spiritual traditions, esoteric writings, altered states of consciousness, and intuitive practices. Influences include the writings of Edgar Cayce and Jane Roberts, along with years of collaboration with trance channel Kevin Ryerson.
According to Dr. Allen, these experiences and studies helped deepen his interest in the spiritual and symbolic role sound may have played within ancient civilizations, particularly ancient Egypt.
For the ancient Egyptians, sound was considered sacred and was closely connected to healing, consciousness, and spiritual initiation. The Acoustical Pyramid was developed as a modern exploration of those ideas through meditation, resonance, and immersive sound experiences.
The Acoustical Pyramid developed in two primary stages.
The first stage focused on recreating the standing-wave acoustics of the King’s Chamber within the Great Pyramid through carefully arranged frequencies and sound simulations. Early experimentation included anecdotal EEG observations that appeared to show shifts in meditative states and changes in brain-wave activity during listening sessions.
The second stage expanded into recordings made within the pyramids themselves. Chants, frequencies, and resonant sounds were captured in situ within the pyramids at Giza and incorporated into a growing library of meditations designed to support reflection, stillness, consciousness exploration, and spiritual growth.
Over time, these explorations evolved into the meditation experiences now included within the Acoustical Pyramid.
At the center of Dr. Allen’s work is the belief that sound, intention, stillness, and consciousness are deeply connected.
The Acoustical Pyramid is intended as a tool for meditation, introspection, spiritual exploration, and personal growth through sound. Each meditation is designed to create space for reflection, inner quiet, and deeper awareness through immersive frequencies, resonance, and guided intention.
Listeners are encouraged to approach the experience openly and consistently, allowing the meditations to unfold gradually over time.
