Question: do alpha waves actually work?
Answer: Alpha Waves (7.5 to 12.5 hz) can help you get into a relaxed, but awake state. ... So, using lower end Gamma waves can help you concentrate, while using waves below Gamma but within Beta might even make your thinking even clearer. Delta Waves (0.5 to 2 hz) can help induce slow wave sleep, or a deeper sleep.
