“…two tones that differ in frequency (one presented to each ear) result in an interaction that can be perceived as a fl uctuating sound). Other studies that have evaluated the human ASSR have also found that a binaural interaction component exists in response to tonebursts centered around 500 kHz (Hink et al, 1980;Krishnan & McDaniel, 1998). These results are all in agreement with the present study, which found that there are indeed, central interactions between two stimuli when they are presented to opposite ears.…”

The auditory steady-state response (ASSR) is an auditory evoked potential which follows the envelope of the stimulus. One of the advantages of the ASSR is that multiple stimulation frequencies can be tested simultaneously. In experiment 1, we evaluated the effects of simultaneously presenting two separate stimuli on ASSR response amplitude. In experiment 2, we evaluated the effects of presenting two ASSR-generating stimuli monotically vs. dichotically, either ipsilaterally or contralaterally to the recording electrode. Recordings were made from the chinchilla inferior colliculi, in response to tonebursts, two-tones, or sinusoidally-amplitude modulated tones. We found that the addition of a second stimulus resulted in a reduction in ASSR response amplitude at moderate to high stimulus levels. The amount of amplitude reduction was typically larger in the monotic (e.g. approximately 50%) vs. dichotic condition (e.g. approximately 10-20%), regardless of whether the responses were recorded ipsilaterally or contralaterally to the ear of stimulus presentation. In conclusion, central as well as peripheral interactions contribute to the reduction in ASSR amplitude in response to the simultaneous presentation of multiple stimuli.

“…Evidence from psychoacoutical and physiological studies in humans suggests that the binaural beat phenomenon is most robust for small frequency differences of the primary tones (Licklider et al, 1950;Perrott and Musicant, 1977;Hink et al, 1980) The frequency difference between the primaries in the present study (85 Hz) was typically larger than the one employed by previous dichotic investigations. However, this was the smallest primarytone frequency difference that elicited robust distortion products in the monotic condition, making comparisons between conditions feasible.…”

“…Additional evidence of dichotic distortional processes was provided by auditory evoked potentials recorded in humans. Hink et al (1980) reported electrophysiological evidence of binaural beats in scalp-recorded waveforms in humans stimulated with dichotic tones. The beat frequency appeared to correspond to the difference between the primary tones, consistent with the appearance of a dichotic QDT distortion product.…”

“…Nevertheless, a number of reports have found that short bursts of binaural beats can elicit clear changes in the EEG. For instance, Hink et al (1980) played tones in short bursts of 100 milliseconds, Schwarz and Taylor (2005) played binaural beats in short bursts of 1200ms, Pratt et al (2010) presented binaural beats for bursts of 2000ms and Grose and Mamo (2011) presented tones in bursts of a little under 2 seconds. It may be that presenting the binaural beats in short bursts provides a stronger more robust auditory stimulus and as such is more capable of eliciting a response in the EEG.…”

“…According to Hink et al (1980) the FFR arises from the brain stem. They suggest that the FFR stems from converging input from overlapping neuronal populations and that this can be directly influenced by binaural beats.…”

A binaural beat can be produced by presenting two tones of differing frequency, one to each ear. Such auditory stimulation has been suggested to influence behaviour and cognition via the process of cortical entrainment. However, research so far has only shown frequency following responses in the traditional EEG frequency ranges of delta, theta and gamma.Hence a primary aim of this research was to ascertain whether it would be possible to produce clear changes in the EEG in either the alpha or beta frequency ranges. Such changes, if possible, would have a number of important implications as well as potential applications.A secondary goal was to track any observable changes in EEG throughout the entrainment epoch to gain some insight into the nature of the entrainment effects any changes in an effort to identify more effective entrainment regimes. Twenty two healthy participants were recruited and randomly allocated to one of two groups, each of which was exposed to a distinct binaural beat frequency for ten 1-minute epochs. The first group listened to an alpha binaural beat of 10Hz and the second to a beta binaural beat of 20Hz. EEG was recorded from the left and right temporal regions during pre-exposure baselines, stimulus exposure epochs and post-exposure baselines. Analysis of changes in broad-band and narrow-band amplitude, and frequency showed no effect of either binaural beat frequency eliciting a frequency following effect in the EEG. Possible mediating factors are discussed and a number of recommendations are made regarding future studies, exploring entrainment effects from binaural beat presentation.3
