The large slow brain waves associated with sleep are called delta waves. These waves are typically observed during deep sleep stages.
Brain waves change throughout the stages of sleep. During deep NREM sleep, slow-wave brain waves predominate. REM sleep is characterized by rapid and desynchronized brain waves similar to wakefulness. These changes in brain wave activity help regulate sleep cycles and promote essential functions like memory consolidation and restoration.
During sleep, different brain waves are produced depending on the sleep stage. For example, during REM (rapid eye movement) sleep, the brain exhibits beta and theta waves, while in non-REM sleep stages, delta waves are prominent. Delta waves are associated with deep sleep and are typically seen in stages 3 and 4 of non-REM sleep.

Delta waves
The brain wave associated with deep sleep is called delta waves. These slow brain waves are characteristic of the deepest stages of non-rapid eye movement (NREM) sleep. Delta waves are most prominent during the restorative stage of sleep known as slow-wave sleep.
Delta waves
Sound waves are detected by the ear. Sound waves are longitudinal waves that require a medium, such as air, to travel through. These waves cause vibrations in the eardrum, which are then converted into electrical signals that are interpreted by the brain as sound.
Brain waves measure the electrical activity generated by neurons in the brain. They reflect different states of consciousness, attention, and alertness. Brain wave patterns are detected using electroencephalography (EEG) technology.

The frequency of your brain waves during REM sleep are beta (which incidentally occurs during the waking state as well). These are low voltage, high frequency waves.
The large, slow brain waves that are associated with deep sleep are called delta waves. They typically have a frequency of less than 4 Hz and are important for restorative sleep and bodily functions such as growth and immune responses.
