Monroe Sound Science

Monroe Sound Science is our proprietary sound technology produced exclusively by the Monroe Institute and used in our program, products and Expand meditation app. 

Monroe Sound Science is a combination of sound techniques that include binaural beats, as well as frequency, amplitude, phase modulation and more. Today, we utilize more than 50 different techniques for creating sound frequencies designed to assist listeners to rapidly move into targeted beneficial states of expanded awareness. 

Bob Monroe was an innovator, and the Monroe Institute continues his legacy through the advancement of our Monroe Sound Science and programs. Research and experiential use has proven its effectiveness.

Brainwave Frequencies

Brainwaves are produced by synchronized electrical pulses from masses of neurons communicating with each other. The human brain contains an average of 86 billion nerve cells called neurons. Neurons generate and transmit electrical signals (brainwaves) that transmit information.

At Monroe, we map and measure the effects of our sound technology, Monroe Sound Science, on brainwave frequencies using EEG. This allows us to create meditation exercises that produce brainwave entrainment effects that achieve specific desired states of consciousness. Below is a participant in Monroe's Discovery program.


Brainwave Entrainment

Brainwave entrainment, also referred to as brainwave synchronization or neural entrainment, as used in Monroe research, refers to the natural synchronization of brainwaves to the rhythm of periodic external stimuli, such as drumming, ocean waves, binaural beats, and other types of sound technology that encourages entrainment. Monroe Sound Science incorporates many types of audio technology.

  • Binaural Beats
  • Monoaural
  • Isochronic Tones
  • Frequency Modulation
  • Spatial Angle Mondulation
  • ...and more

At Monroe Institute, we use Monroe Sound Science as a tool for research studies and the active exploration of consciousness in our experiential programs. Our research focuses on the following objectives: 

  • Establishment and facilitation of coordinated studies of human consciousness using interdisciplinary approaches
  • Promote the understanding that consciousness research is most meaningful when there are practical applications
  • Search for and investigation of various tools and techniques to facilitate evocative and transformative altered states of consciousness
  • Publishing the results of our consciousness research studies
  • Providing a forum for dialogue regarding consciousness research, the ethics and future of the field and application of consciousness research

Participating in Research

If you are considering participating in one of our research studies during your retreat at our Virginia campus, you may email Nancy at or call her at 434-361-1500 for more information.

Research Collaborators

Monroe partners with organizations such as IONs and the University of Virginia's  Division of Perceptual Studies to research conduct additional studies on the benefits and effects of our audio technology and programs. These studies are exploring the effect of Monroe Sound Science on brainwave activity, including synchronous gamma frequencies that could be indicating a bridge of awareness from subconscious to super-conscious states.

If you wish to conduct research in collaboration with our team of researchers please submit a formal proposal to the above email in adherence to our professional and ethical

Current and Upcoming Research Studies

  1. Discovery (Monroe Sound Science and other audio-technology)
  2. ASSEP (Audio Study State Evoked Potential)
  3. Copper Wall Project
  4. Distant Healing Intention

As this research unfolds, Monroe Sound Science technology will continue to grow in its support of the study and experience of expanded states of consciousness.
