A recent study showed that binaural beats have an impact on the efficiency of allocating attention over time. We were interested to see whether this impact affects attentional focusing or, even further, the top-down control over irrelevant information. Healthy adults listened to gamma-frequency (40 Hz) binaural beats, which are assumed to increase attentional concentration, or a constant tone o...

Human creativity relies on a multitude of cognitive processes, some of which are influenced by the neurotransmitter dopamine. This suggests that creativity could be enhanced by interventions that either modulate the production or transmission of dopamine directly, or affect dopamine-driven processes. In the current study we hypothesized that creativity can be influenced by means of binaural bea...

A binaural beat is the perceptual experience that occurs when two tones of slightly different frequencies are presented dichotically, creating the experience of a third tone corresponding to the difference in frequencies. Many temporary cognitive effects have been linked to the presentation of a binaural beat, including increased working memory capacity. In the present study, a version of the f...

Binaural beats are auditory brainstem responses which originate in the superior olivary nucleus of each hemisphere. They result from the interaction of two different auditory impulses, originating in opposite ears, below 1000 Hz and which differ in frequency between one and 30 Hz (Oster, 1973).For example, if a pure tone of 400 Hz is presented to the right ear and a pure tone of 410 Hz is prese...

Binaural beats are subjective hearing sensations, which occur when one of tone signals is applied to one ear, and the other one, with a slightly different frequency is applied to the second ear. A listener then receives a resultant sound with an amplitude which changes with a frequency equal to the difference of frequency of applied signals. The aim of this thesis was to examine the influence o...

Enhancing human cognitive performance is a topic that continues to spark scientific interest. Studies into cognitive-enhancement techniques often fail to take inter-individual differences into account, however, which leads to underestimation of the effectiveness of these techniques. The current study investigated the effect of binaural beats, a cognitive-enhancement technique, on attentional co...

An initial experimental study was conducted to evaluate the effects of binaural beats on fish growth performance. A 90-day trial with four triplicate groups was conducted with 240 zebrafish, Danio rerio, under aquarium conditions. Binaural beat file complexes were played for each aquarium using computer controlled directional speakers for 0 min d-1(Control), 90 min d-1(Group 1), 180 min d-1 (Gr...

Binaural beats are defined as auditory perceptions, occuring when two tones of slightly different frequencies are presented separately to each ear. When the binaural beat beats with the frequency that corresponds to the state of alpha wave range, than it is believed that the overall brain activity changes accordingly. In this study it is assumed that binaural beat corresponding to alpha wave ra...

When two pure tones of slightly different frequencies are delivered simultaneously to the two ears, is generated a beat whose frequency corresponds to the frequency difference between them. That beat is known as acoustic beat. If these two tones are presented one to each ear, they still produce the sensation of the same beat, although no physical combination of the tones occurs outside the audi...
