Our brain waves typically range from 0.5 to 100 Hz, with different frequencies corresponding to different states of consciousness such as delta (0.5-4 Hz), theta (4-8 Hz), alpha (8-14 Hz), beta (14-30 Hz), and gamma (30-100 Hz). These frequencies can change depending on our mental and emotional state.
When awake, you typically exhibit beta brain waves, which are associated with focused attention, alertness, and cognitive processing. These brain waves have a higher frequency compared to other states such as relaxation or deep sleep.
Gamma waves were discovered by a German neuroscientist in the 1960s and are a type of brain wave associated with cognitive functions such as attention, memory, and problem-solving. They are high-frequency brain waves, ranging from 30-100 Hz, and are believed to play a role in coordinating communication between different parts of the brain.
Slow waves are a type of electrical activity that occurs within the brain during deep sleep. These waves are characterized by their slow frequency and high amplitude, and are believed to play a role in consolidating memories and promoting overall brain health. Monitoring slow waves can provide insights into the quality of sleep and brain function.
High frequency waves will have more energy than low-frequency waves. This is because energy is directly proportional to frequency in waves - the higher the frequency, the higher the energy.
Brain waves can be measured in units of frequency, typically in Hertz (Hz). The main types of brain waves are delta waves (0.5-4 Hz), theta waves (4-8 Hz), alpha waves (8-12 Hz), beta waves (12-30 Hz), and gamma waves (>30 Hz). These frequencies correspond to different states of consciousness and mental activity.
High frequency and low amplitude.
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 relationship between EEG waves frequency and cognitive function is that different frequencies of brain waves are associated with different cognitive states. For example, higher frequency brain waves like beta waves are linked to active thinking and problem-solving, while lower frequency waves like delta waves are associated with deep sleep and relaxation. Monitoring EEG waves can provide insights into a person's cognitive function and mental state.
Gamma waves are the most desynchronous brain waves, as they have the highest frequency (above 30 Hz) and are associated with cognitive processes such as problem-solving and attention. These waves are not synchronized across the brain and are indicative of high mental activity.

Sound is pressure waves travelling through the air. The brain can detect the difference in sound frequency, based on the distance between pressure waves, by the ear which physically responds to incoming sound waves. Volume, frequency and direction are identified, then translated and sent to the brain as electrical signals.

Listening to music at 440 Hz can have a calming effect on the brain, promoting relaxation and reducing stress levels. This frequency is believed to resonate with the natural frequency of the brain, helping to synchronize brain waves and improve focus and concentration.
