In order to develop a method for increasing concentration, biofeedback training by means of the prevalent EEG was made for many students at a women's university 18 to 22 years of age. EEG amplifiers picked up the EEG at Fp_2 position , and divided it into six bandpass waves (the rheta_2, alpha_1, alpha_2, alpha_3, beta_2 waves and the artifact). It distinguished one dominant wave in the EEG in each 2 second interval. The speed of A/D conversion is 20ms. The amplitude of these six bandpass waves is an output with a 1/256 resolution of the full scale every 2 seconds.As a result, the following conclusions were obtained.1. A high level of concentration is accompanied by a large time fraction of the alpha_2 wave being prevalent in the EEG,i. g., by a high appearance of the alpha_2 wave.2. Intensification of the alpha_2 wave can be accomplished by biofeedback training of the prevalent EEG.3. Concentration level can be increased by the intesification of the alpha_2 wave accomplished by biofeedback training.4. There exists differences among individuals in a person's comfortable feelings caused by sound.5. Quality and quantity differences of the comfortable feelings for sound bring about the differences of EEG.In general, those who show high levels of comfortable feelings for the sound of nature have a tendency towards low prevalent Fp_2beta_2 waves, while those at high levels of comfortable feelings for the sound of city life show high prevalent Fp_2beta_2 waves.The time fraction of each wave prevalent in EEG is a reasonable measure of psychological response more than the time average of EEG amplitude.

为了开发一种提高注意力的方法，在一所女子大学对许多18至22岁的学生进行了生物反馈训练。脑电放大器采集Fp_2位置的脑电信号，并将其分成6个带通波（rheta_2、alpha_1、alpha_2、alpha_3、beta_2和伪影）。它在每2秒间隔内区分EEG中的一个主导波。A/D转换速度为20 ms。这六个带通波的振幅是每2秒输出一个满量程分辨率为1/256的输出。高水平的集中伴随着在EEG中占主导地位的α_2波的大的时间分数，即。例如，在一个实施例中，由α_2波的高出现。α_2波的强化可以通过对流行EEG的生物反馈训练来完成。通过生物反馈训练强化α_2波，可提高集中水平.人对声音的舒适感存在个体差异。听觉舒适感的质和量的差异导致了脑电的差异，一般说来，听觉舒适感高的人，其Fp_2 β_2波的优势频率较低，而那些对城市生活的声音感到舒适的人则表现出较高的普遍Fp_2 β_EEG中普遍存在的每个波的时间分数是比EEG振幅的时间平均值更合理的心理反应的度量。
