med.EEG-frequency-band Calculator
Identifies the dominant EEG frequency band (delta, theta, alpha, beta, gamma) from a peak frequency and amplitude, and classifies the associated brain state. Alpha dominates in relaxed wakefulness; gamma is associated with focused cognition and sensory binding.
Inputs
Dominant Freq Hz
Cycles per second (Hz). Audible sound: 20 Hz – 20 kHz. Make sure units match what the formula expects.
Amplitude Uv
Maximum displacement from equilibrium. Energy carried by a wave is proportional to amplitude squared.
Age Years
Age in completed years. Many health and fitness formulas adjust for age.
Results
frequency band
Sample size or count used in the calculation.
expected alpha peak for age (Hz)
pH of the solution. Below 7: acidic. 7: neutral. Above 7: basic (alkaline).
power estimate (μV²)
The value at the specified point or condition.
clinical significance
Sample size or count used in the calculation.
alpha reactivity
Rate of radioactive decay events per second (becquerels or curies). Decreases exponentially with time.
