It was found that the duration of deep sleep was longer in participants who listened to binaural beats compared to those who didn’t. The beats used were in the delta range, which are associated with deep sleep. It was observed that people exposed to binaural beats in the beta range recalled more words correctly than those exposed to binaural beats in the theta range.Ī 2018 study looked at how low-frequency binaural beats affected sleep in 24 participants. Participants listened to binaural beats that were either in the beta or theta range, which are associated with an active mind and sleep or tiredness, respectively.Īfterward, participants were asked to perform recall tasks. Binaural beatsĪ 2019 study investigated how binaural beats affected memory in 32 participants. While research into isochronic tones is lacking, some research into the effectiveness of binaural beats, monaural beats, and brain wave entrainment has been performed. This means that there was a variation in pitch, in the interval between tones, or in both. However, the tones used in these studies haven’t been isochronic in nature. Some studies have used repeating tones to study brain wave entrainment. Because of this, additional research is needed to determine if isochronic tones are an effective therapy. There haven’t been very many research studies performed on isochronic tones specifically. Listening to isochronic tones within the alpha wave frequency may be examined as a way to induce a state of relaxation or aid in meditation. The intermediate type of brain wave, alpha waves, occurs in a relaxed state.Listening to a high frequency isochronic tone could possibly aid in attentiveness or concentration. Higher frequency brain waves, such as gamma and beta waves, are associated with an active, engaged mind. ![]() Therefore, listening to a low frequency isochronic tone might potentially help to promote better sleep.
