The participants in this study listened to 30 minutes of binaural beats before surgery. A 2005 study involving more than 100 participants who were due to receive general anesthesia for a day procedure reported a decrease in preoperative anxiety after exposure to a delta wave binaural beat. However, the authors stated that it warranted further study only as a therapeutic measure to support conventional treatments for anxiety.ĭespite this, other researchers have continued to investigate this therapy. Share on Pinterest A person may reduce anxiety before surgery by listening to binaural beats.Įarly research from 2001 suggested that binaural beat therapy may yield some benefit for people with mild anxiety. The study authors suggest that these frequencies promote maintenance of arousal while a person is awake.
Gamma pattern: This frequency pattern accounts for a range of 30–50 Hz. However, it can also increase anxiety at the higher end of the range. This frequency range may help promote concentration and alertness. Beta pattern: Binaural beats in the beta pattern are at a frequency of 13–30 Hz. Alpha pattern: Binaural beats in the alpha pattern are at a frequency of 7–13 Hz and may encourage relaxation. Theta patterns contribute to improved meditation, creativity, and sleep in the rapid eye movement ( REM) phase. Theta pattern: Practitioners set binaural beats in the theta pattern to a frequency of 4–7 Hz. In the study, people who received a delta pattern frequency during sleep entered a deeper stage of sleep, according to electroencephalogram (EEG) brain scan results. Delta pattern: Binaural beats in the delta pattern operate at a frequency of 0.5–4 Hz with links to a dreamless sleep. The study authors explain that there are five different categories of frequency pattern: The findings of a 2018 study suggest that listening to binaural beats for a recommended period can affect a person’s subsequent behavior and sleep cycles. The binaural beat that a person perceives is the frequency difference between the waves entering the left and right ear.įor example, if the left ear registers a tone at 200 Hz and the right ear registers one at 210 Hz, the binaural beat is 10 Hz - the difference between the two frequencies. There are three types of apps that can help you with getting better sleep: apps to help you fall asleep, apps that keep you from waking up, and apps that track the length and quality of your sleep.Īs some apps are designed for you to listen as you fall asleep, or to listen all night, you could invest in a pair of Sleepphones, which are more comfortable than lying on earbud-style headphones.Share on Pinterest Binaural beats therapy may help treat anxiety, stress, and related disorders.Īccording to a 2015 literature review, the tones should be at frequencies lower than 1,000 hertz (Hz) for the brain to detect the binaural beat. Getting better sleep is something we all hope to achieve at some point and luckily there are plenty of digital aids out there which can be downloaded with one tap. 
If you want to give it a try, why not test out a pink noise sleep app? Sleeping with pink noise has been found to improve listeners' memories the following day.
White noise is of the same volume at all frequencies, whereas pink noise is louder in the lower frequencies – the same as in some natural sounds such as heartbeats and the sound of traffic. This is why some people find it easier to sleep with the gentle hum of white noise in the background. You may find it hard to sleep in silence, as a sudden noise is more noticeable and likely to wake you up, or be bothered by the sound of traffic or a snoring partner, particularly if the noise is not part of your usual sleeping environment.
