Common questions
What is sound therapy?
Sound therapy is the clinical and wellness use of specific audio frequencies — including binaural beats, singing bowls, and tuning forks — to influence brainwave activity, reduce stress, and support healing. Peer-reviewed research shows certain frequencies can lower cortisol, improve sleep quality, and reduce anxiety scores on standardized scales.
Are binaural beats scientifically proven?
A 2019 meta-analysis of 22 studies in Psychological Research found binaural beats produce a moderate anxiety-reduction effect (g = 0.45). They also show measurable influence on EEG brainwave patterns. However, results vary by frequency, session length, and individual — they work best as a complementary tool alongside other wellness practices.
How do I choose the right sound for sleep?
Start with pink noise or white noise if you need to mask environmental disruptions. For deeper sleep, try delta-frequency binaural beats (1-4 Hz). Studies show pink noise can increase deep sleep by 23%. Experiment with 2-3 options over a week, keeping volume below 60 dB, and track which produces the best subjective sleep quality.
Is it safe to listen to sound therapy every day?
Yes, daily listening is safe for most adults when following basic guidelines: keep volume at or below 70 dB (roughly conversation level), limit binaural beat sessions to 30-60 minutes, and use open-back headphones or speakers when possible. People with epilepsy or seizure disorders should consult a physician before using binaural beats.
Do I need headphones for binaural beats?
Yes — binaural beats require stereo headphones to work because they rely on delivering slightly different frequencies to each ear. Your brain perceives the frequency difference as a third tone. Over-ear headphones provide the best seal and frequency response, though any stereo headphones or earbuds will produce the effect.
