Please note: The Brainlink Lite EEG headband (a consumer neurofeedback device that pairs with Healium), classifies delta waves as 0- 2.75Hz, meaning that it’s important to keep in mind that the amount of delta you can expect to see when practicing neurofeedback at home with Healium will be much smaller.įor the purposes of this article, we’ll be classifying delta brainwaves as electrical impulses in the brain occurring at a frequency of up to 4 Hz.

Generally speaking, delta waves are seen as frequencies ranging from 0-4 Hz. Delta brainwaves are the slowest recordable brainwave frequency, however the accepted range for each of the different types of brainwaves varies.
