22 When two tones with slightly different frequencies are presented to both ears, they interact in the 23 central auditory system and induce the sensation of a beating sound. At low difference 24 frequencies, we perceive a single sound, which is moving across the head between the left and 25 right ears. The percept changes to loudness fluctuation, roughness, and pitch with increasing beat 26 ra...

In a project that has been funded by the German Ministery of Research and Technology (BMFT) fundamental questions of noise valuation have been addressed by an interdisciplinary research consortium. The aim of the project was to provide knowledge that will lead to a new, binaural and aurally-adequate measurement technique which can especially be used for the valuation of the effects of noise for...

Binaural beats (BBs) are an auditory illusion occurring when two tones of slightly different frequency are presented separately to each ear. BBs have been suggested to alter physiological and cognitive processes through synchronization of the brain hemispheres. To test this, we recorded electroencephalograms (EEG) at rest and while participants listened to BBs or a monaural control condition du...

The presentation of two sinusoidal tones, one to each ear, with a slight frequency mismatch yields an auditory illusion of a beating frequency equal to the frequency difference between the two tones; this is known as binaural beat (BB). The effect of brief BB stimulation on scalp EEG is not conclusively demonstrated. Further, no studies have examined the impact of musical training associated wi...

The binaural resynthesis subtest of the WilIeford Test Battery (1977) was administered to a sample of 56 children with an average age of 8 years. 8 months. in order to investigate test characteristics. Analysis revealed that 19 of 40 items fell outside the optimal range for item difficulty. In addition, a significant difference was found between right and left ear scores, and a significant corr...
