The effect of different levels of continuous tones vibrant on focus ability in teenagers

This study investigated the effect of continuous tones vibrant on focus ability among teenagers. Three vibrant levels as perceived as Medium, Loud but Comfortable and Very Loud were examined. In 6 subjects, the results showed that the amplitude of N1 waves have reduced significantly when stimulated by Medium sound as compared to Loud but Comfortable and Very Loud stimulation. Insignificant reduction of N1 amplitude was increased as the tones vibrant changed from Loud but Comfortable to Very Loud stimulation. In particular, the Very Loud stimulation evoked constant amplitude of N1 throughout stimulation in most of the subjects. This shows that a high vibrant of tones project high focus ability. The finding could be used for a basis of developing an awareness system or a diagnostic for mental disorder such as schizophrenia.
