When evaluating responses for the individual beat frequencies, positive effects on state anxiety were observed for all monaural beat conditions compared to control stimulation. “Monaural beat stimulation was found to reduce state anxiety. What are monaural beats good for? Monaural beats and anxietyĪccording to a study entitled The Impact of Monaural Beat Stimulation on Anxiety and Cognition: Great! Now let’s get into some of the research on monaural beats. Binaural beats are heard more readily when beat frequencies are low and carrier tones are below 1,000 hz. Monaural beats are heard across a wide beat frequency range and with higher carrier tones.Monaural beats are able to be perceived by one or both ears, whereas binaural beats require both ears (and headphones).Since the cochlea is located in the inner ear and the medial superior olivary nuclei is located in the pons, which is part of the brainstem, I suspect that monaural beats can lead to brainwave influencing and entrainment quicker due to the fact that the sounds reach the cochlea much quicker than reaching the brainstem. Monaural beats are demodulated in the cochlea, whereas binaural beats are processed in the medial superior olivary nuclei.This means that not everyone will experience binaural beats. Monaural beats are objective beating patterns while binaural beats are a subjective perception.Here is one last comparison of monaural beats and binaural beats before we move on to other information on auditory beat stimulation. In order to hear the tones of binaural beats separately, it is imperative to use headphones to experience binaural beats. Binaural beats are generated when the sine waves within a close range are presented to each ear separately.” The beat corresponds to the difference between the two frequencies (in this case 40 Hz). “Monaural beats are physical beats, which are objectively heard when the combination of two sine waves at neighboring frequencies (e.g., 400 and 440 Hz) are summated and presented to each ear at the same time resulting in an amplitude modulated (AM) signal. Therefore, monaural beats are physical beats, whereas binaural beats are perceived beating patterns that arise from slightly different frequencies.Īgain, to repeat the differences between monaural beats and binaural beats, let’s consider this paragraph from Auditory Beat Stimulation and its Effects on Cognition and Mood States : We can also classify monaural beats as auditory beats that are “amplitude-modulated signals”, whereas binaural beats are auditory signals that subjectively cause the perception of an amplitude modulation. Binaural beats require headphones to experience as they are two different sine waves of neighboring frequencies that are delivered to each ear separately. What are monaural beats? Monaural beats are beats comprised on neighboring frequencies that are delivered to both ears simultaneously. Considering the difference between monaural beats and binaural beats The authors of this study concluded that sound-based treatments can be effective in reducing state anxiety and have the potential to offer a simple and easily distributable method of treating anxiety in the segment of the population that experiences anxiety in this manner. What are monaural beats? Monaural beats are one type of auditory beat stimulation (ABS).Īccording to Neuroscience News, “Auditory beat stimulation involves combinations of tones, played in one or both ears, designed to trigger changes to brain activity.” Today we are looking at the question, “What are monaural beats?” and we get into some studies that dictate why monaural beats are so awesome! Understanding monaural beats & auditory beat stimulation What are monaural beats? Learn all about monaural beats and binaural beats, including why monaural beats may be more impactful for entrainment than binaural beats
