Beta (Mid)
20.00 Hz
20 Hz is in the middle of the beta band of brain activity, as recorded by EEG (sensors on the scalp).
How well is this supported?
Measured directly, or defined by a published standard.
The band is a standard way of describing EEG recordings. Band edges are conventions, and what a person experiences varies. This is not medical information.
The button plays a plain tone. Start with the volume low. Phone and laptop speakers play low notes quietly; headphones or a speaker help.
About this number
20 Hz is in the middle of the beta band of brain activity, as recorded by EEG (sensors on the scalp). A 2017 glossary from the International Federation of Clinical Neurophysiology (IFCN) puts beta at 14 to 30 Hz. Band edges are conventions and vary by source. Beta activity is associated with active wakefulness.
