Can Binaural Beats Help With Anxiety and Depression?
Binaural beats are auditory illusions that happen when you listen to two slightly different frequencies in each ear. Your brain then perceives a third “beat” frequency, which is the difference between the two tones, and some are exploring the benefits of 432 Hz binaural beats.
Anxiety and depression are common mental health conditions that impact people all over the world. As these conditions become more prevalent, people are exploring alternative and complementary therapies to manage their symptoms. This includes the use of binaural beats for anxiety and depression.
Binaural beats are a noninvasive and potentially affordable way to self-manage anxiety and depression symptoms, and there are also free apps for mental health that can provide additional support.

The science behind binaural beats
Binaural beats are a fascinating concept, and understanding the science behind them can help you decide if they’re right for you. Here’s a breakdown of how they work:
How Binaural Beats Work
When you listen to binaural beats, your brain processes them in the brainstem, specifically in a region called the superior olivary nucleus. This processing triggers neural activity that can be measured with an EEG, a test that measures electrical activity in the brain.
This all leads to something called brainwave entrainment. Brainwave entrainment is when your brain’s electrical activity starts to synchronize with external stimuli, like binaural beats. Different frequencies of binaural beats are linked to different brainwave states. For example, delta waves are linked to sleep, theta waves to relaxation, alpha waves to calmness, and beta waves to focus.
Frequency Ranges and Their Associations
Here’s how different frequency ranges of binaural beats are thought to impact your state of mind:
- Delta (1-4 Hz): Deep Sleep and Relaxation. Delta waves are associated with deep sleep, relaxation, and lessened feelings of anxiety.
- Theta (4-8 Hz): Meditation and Creativity. Theta waves are linked to meditative states, increased creativity, and stress reduction.
- Alpha (8-14 Hz): Relaxation and Calmness. Alpha waves are associated with relaxation, calmness, and lower anxiety.
- Beta (14-30 Hz): Focus and Alertness. Beta waves are linked to feeling alert and focused and help with cognitive processing. However, higher beta frequencies can also be linked to anxiety.
How researchers study binaural beats
Systematic reviews gather all the research on a particular topic and use strict methods to assess the quality of that research. Researchers then summarize the findings of the highest-quality studies.
To conduct a systematic review on binaural beats for anxiety and depression, researchers start by searching databases like PubMed and Scopus. They use keywords like “binaural beats,” “anxiety,” and “depression” to find relevant studies.
Next, researchers must choose which studies to include based on specific criteria. For example, they might only include randomized controlled trials. They might also focus on studies that include certain people.
Finally, researchers must assess the quality of the studies they include. They may use a tool like the Cochrane risk-of-bias tool to see whether the studies are likely to be reliable. This helps them focus on the best-quality evidence.
What does the science say about binaural beats and anxiety?
Researchers have been exploring whether binaural beats can ease the symptoms of anxiety. A systematic review looked at a bunch of studies to see what they found. Some of the studies looked at generalized anxiety disorder, social anxiety, and anxiety before a surgery.
The studies measured anxiety using tools like the State-Trait Anxiety Inventory (STAI), the Beck Anxiety Inventory (BAI), and the Hamilton Anxiety Rating Scale (HARS).
Here’s a quick look at some of the findings from the studies that were included in the review:
- Isik, BK et al. 2017: This study looked at how binaural beats affected anxiety in people having surgery.
- Padmanabhan, R et al. 2007: This research explored the effects of binaural beats on anxiety and cognition.
- Opartpunyasarn, P. et al. 2022: This study looked at the effects of binaural beats for anxiety and sleep quality.
- Menziletoglu, D et al. 2021: This study used binaural beats to treat anxiety in people with tinnitus.
- Loong, LJ et al. 2022: Researchers used binaural beats to treat anxiety in people with heart disease.
- Wiwatwongwana, D et al. 2016: This study looked at the effects of binaural beats on anxiety and pain.
- Olcucu, MT et al. 2021: Researchers looked at whether binaural beats could help with anxiety before surgery.
- Parodi, A et al. 2021: This study explored the effects of binaural beats on anxiety and stress.
- Daengruan, P et al. 2021: This study used binaural beats to treat anxiety and depression.
- Galvez, G et al. 2005: Researchers explored the effects of binaural beats on anxiety and relaxation.
- Prasad, M et al. 2023: This study looked at the effects of binaural beats on anxiety and sleep.
- Ligree N et al. 2023: This study used binaural beats to treat anxiety in people having surgery.
It’s important to note that these studies all used different binaural beat frequencies and carrier frequencies. They also used different intervention times and types.
[If the systematic review included a meta-analysis, summarize the overall effect size of binaural beats on anxiety. Discuss any subgroup analyses performed, such as by type of anxiety disorder or binaural beat frequency.]
While these studies are interesting, it’s important to remember that they have some limitations. For example, some of the studies had small sample sizes, and the methods weren’t always consistent. There’s also the possibility of bias in some of the studies.
More research is needed to know for sure whether binaural beats can really help with anxiety. Future studies should use larger samples and standardized protocols.
Do binaural beats help with depression?
Several studies have explored whether listening to binaural beats can help alleviate depression symptoms. A systematic review likely included a summary of these studies. This would include the different ways researchers measured depression in the study participants. Common assessment tools include:
- Beck Depression Inventory (BDI)
- Hamilton Depression Rating Scale (HDRS)
- Patient Health Questionnaire-9 (PHQ-9)
The review would have highlighted the specific findings of each study, noting the binaural beat frequencies and carrier frequencies used, as well as how long people listened to the beats and the type of intervention used. For example, some studies may have had participants listen to binaural beats while relaxing at home, while others may have used the beats during a guided meditation session.
Ideally, the systematic review also included a meta-analysis. This is where the researchers combine the results of multiple studies to get a better overall sense of whether binaural beats are effective for depression. The meta-analysis might have provided an “effect size,” which is a number that tells you how big of an impact the binaural beats had on depression symptoms. It’s also possible the researchers looked at whether certain groups of people, such as those with more severe depression, responded better to binaural beats, or whether certain binaural beat frequencies were more effective.
It’s important to keep in mind that research in this area is still developing. Many studies have small sample sizes, and the methods used can vary quite a bit. This makes it difficult to draw firm conclusions about whether binaural beats are truly effective for everyone with depression. More rigorous studies with larger groups of people and standardized methods are needed to confirm these findings. It’s also important to note that there is always a risk of bias in any research.
What affects how well binaural beats work?
If you want to try binaural beats for anxiety or depression, you should know that some things can make them more or less effective.
Binaural Beat Frequency
The specific frequency of the binaural beat matters. Alpha frequencies are often used for relaxation, while theta frequencies are used for meditation. Certain frequencies could work better for certain people or conditions.
Carrier Frequency
The carrier frequency also plays a role. The carrier frequency can change how you perceive the binaural beat and how well it works. It can also affect your overall listening experience and the outcomes you experience.
Intervention Time
How long should you listen to binaural beats to get the best results? Listening for longer may be more effective, but it may also be harder to fit into your day. If you don’t listen for long enough, you may not experience the benefits.
Masking with Sound
Some people like to listen to binaural beats with other sounds, such as nature sounds or music. Masking sounds can help you relax and make the experience more enjoyable, and some people find that drinking tea, like chamomile or lavender, can also help with relaxation and sleep.
Individual Variability
Binaural beats don’t work the same way for everyone. Your personality, previous meditation experience, and brainwave patterns can all affect how well binaural beats work for you. Some people may find them very helpful, while others may not notice a difference.
How to make binaural beats work for you
If you want to try binaural beats, here are some things to keep in mind.
Choosing the right track
Start with binaural beat tracks designed for relaxation or sleep. Pay attention to the carrier frequency and any masking sounds that are used.
Creating a comfy environment
Find a quiet, comfortable space to listen to binaural beats. Try using noise-canceling headphones to minimize distractions.
Setting realistic expectations
Binaural beats aren’t a quick fix for anxiety or depression. You have to use them consistently, and they work best when you’re also taking care of your mental health in other ways.
Talking to a healthcare professional
If you have any health conditions, or if you’re currently working with a mental health professional, talk to them before using binaural beats. Binaural beats shouldn’t be used instead of medical treatments.
Frequently Asked Questions
What Hz is best for depression and anxiety?
For anxiety, frequencies in the Alpha (8-14 Hz) and Theta (4-7 Hz) ranges are often recommended, promoting relaxation and a meditative state. For depression, some suggest experimenting with frequencies in the Alpha or even Delta (0.5-4 Hz) ranges, though more research is needed to pinpoint optimal frequencies for mood elevation. It’s a very individual experience.
What is the most calming sound for anxiety?
While binaural beats can be calming, the “most calming” sound is subjective. Many find nature sounds like rain, ocean waves, or gentle streams to be highly effective at reducing anxiety. White noise or pink noise can also mask distracting sounds and promote relaxation. Experiment to see what works best for you.
Who should not listen to binaural beats?
While generally safe, certain individuals should exercise caution. Those with epilepsy or a history of seizures should consult a doctor before using binaural beats, as they may potentially trigger seizures in rare cases. Also, individuals with pacemakers or other implanted medical devices should seek medical advice. Finally, those prone to auditory hallucinations should proceed with caution and monitor their experience.
Can binaural beats reduce anxiety?
Research suggests that binaural beats can reduce anxiety for some individuals. Some studies have shown that listening to specific frequencies can promote relaxation, reduce stress hormones, and improve mood. However, the effects can vary from person to person, and it’s not a guaranteed cure. Binaural beats are best used as a complementary tool alongside other anxiety-reducing strategies.
In closing
Right now, the research on binaural beats for anxiety and depression shows some promise, but it’s far from conclusive. Some studies suggest they might help, but the evidence is still pretty limited and needs a lot more digging.
What we really need are bigger, better studies with consistent methods. Future research should zero in on the best binaural beat frequencies, the “carrier” frequencies they’re built on, and how long people should listen for different conditions.
It would also be interesting to see how binaural beats work alongside other treatments, like cognitive behavioral therapy (CBT) or even medication.
Ultimately, binaural beats could be a helpful addition to other therapies for anxiety and depression, but we need more info to be sure about how well they work and how safe they are. So, if you’re thinking about trying them, keep your expectations realistic and definitely chat with a healthcare pro first. They can help you figure out if binaural beats are a good fit for you.
