Read the first 7 Psychoacoustics and Brainwave Entrainment flashcards as text

  1. Which brainwave frequency range is most associated with deep dreamless sleep and the deepest states of meditation?

    Answer: Delta (0.5–4 Hz)

    Delta waves (0.5–4 Hz) dominate during deep, dreamless sleep and the most profound meditative states.

  2. What is the primary auditory mechanism that allows binaural beats to influence brainwave activity?

    Answer: The auditory cortex perceives a phantom beat equal to the frequency difference between the two tones

    The auditory cortex creates a perceived rhythmic beat equal to the difference between two slightly different tones presented separately to each ear.

  3. Isochronic tones differ from binaural beats in that they:

    Answer: Are single tones that are evenly pulsed on and off at a set rate

    Isochronic tones are single audio tones switched on and off at a regular interval, creating sharp pulses that entrain brainwaves without requiring stereo input.

  4. The phenomenon where repeated exposure to a stimulus causes progressively reduced neural response is called:

    Answer: Neural habituation

    Neural habituation is the decrease in response to a stimulus after repeated or prolonged exposure, which is relevant when using entrainment tracks long-term.

  5. Which concept describes the brain's tendency to synchronize its electrical activity with external rhythmic stimuli?

    Answer: Frequency following response (FFR)

    The frequency following response (FFR) refers to the brain's neural tendency to match its oscillatory patterns to the frequency of an external rhythmic stimulus.

  6. At what minimum frequency difference between the two ear tones do binaural beats cease to produce an audible beat perception?

    Answer: Above 30 Hz

    Binaural beats are only perceptible when the frequency difference between the two tones is less than approximately 30 Hz; beyond that, the beat is no longer neurally integrated.

  7. Which meditation music technique uses rhythmic drumming at approximately 4–7 Hz to induce trance-like theta states, rooted in indigenous traditions?

    Answer: Shamanic drumming

    Shamanic drumming at 4–7 beats per second has been used for millennia to induce theta-range trance states for healing and spiritual journeys.
