The electrical pulses produced from masses of neurons communicating with each other form wave-like patterns – hence the term brainwave. ... For instance, when you're producing predominantly slower brainwaves, you feel calm and relaxed. But when higher-frequency brainwaves are dominant, you're super alert.

Can you feel brain waves?

Theta brain waves can also occur when you're awake, but in a very deeply relaxed state of mind; a state that some may describe as “autopilot.” However, if you experience high levels of theta waves while you're awake, you might feel a little sluggish or scattered.

Do brainwaves make noise?

Like audio signals, brainwaves measured by EEG are time series spanning a range of frequencies. ... This means that there is no simple way to 'play' the EEG in sound – at least in a way that will sound good. Raw brainwaves played as audio files sound like nothing more than an unimpressive low frequency rumble.
