Roughly 8–13 Hz in EEG

Alpha · An electrical signal, not a sound

Alpha names a range of patterns observed in EEG, often more prominent during relaxed eyes-closed wakefulness. Boundaries and meaning depend on context and protocol.

01 · What we can say

MeasuredEstablished

Alpha is commonly classified around 8–13 Hz, while research and clinical work may use different boundaries and individual alpha frequency.

02 · What we can say

MeasuredContested

10 Hz in EEG and 10 Hz acoustic modulation are different signal types; a shared number does not prove neural entrainment.
