As control, we evoked a beat ASSR in response to both tones in the same ear. METHODS: We stimulated each ear with a distinct tone, both differing in frequency by 40Hz, to record a binaural beat ASSR. We tested the feasibility to record an auditory steady state evoked response (ASSR) at the binaural beat frequency in order to find a measure for temporal coding of sound in the human EEG. Binaural beat sensations depend upon a central combination of two different temporally encoded tones, separately presented to the two ears.

Human auditory steady state responses to binaural and monaural beats.Ĭlin Neurophysiol. Binaural beat audio has the potential to decrease acute pre-operative anxiety significantly.

No Intervention Group) and 3.8% in the No Intervention Group. No Intervention Group), 11.1% in the Audio Group (p = 0.15 vs. We measured anxiety with the State-Trait Anxiety Inventory questionnaire and compared binaural beat audio (Binaural Group) with an identical soundtrack but without these added tones (Audio Group) and with a third group who received no specific intervention (No Intervention Group). Mean decreases in anxiety scores were 26.3% in the Binaural Group (p = 0.001 vs. Recently, it has been demonstrated that music can be used successfully to relieve patient anxiety before operations, and that audio embedded with tones that create binaural beats within the brain of the listener decreases subjective levels of anxiety in patients with chronic anxiety states. Ambulatory surgery challenges our pre-operative goal of an anxiety-free patient by requiring people to be 'street ready' within a brief period of time after surgery. Pre-operative anxiety is common and often significant. Sunderland Royal Hospital, Sunderland, SR4 7TP, UK.
