subject: Binaural Beats - What Are They & How Do They Work [print this page] For the best effects you must use earphones rather than speakers when listening to Binaural Beats. Earphones are not required when using Monaural Beats or Isochronic Tones. If your hearing is impaired in one ear then Monaural Beats or Isochronic Tones are the best choice. It is advised that you find a quiet place where you will not be disturbed as any interruption can bring you straight out of your desired state of consciousness. If you can relax and let your mind go blank then your recording will be far more effective Finally give it time, the effects are not instant and in most cases you will need to listen to the recording for at least 5 minutes, some minds may take longer, particularly if it is your first time using Binaural Beats.
