Crafting Calm Noise

The Science

The Calm Noise track was meticulously crafted from start to finish, grounded in evidence-led principles.  Alongside Calm’s Chief Clinical Officer, we conducted an extensive exploration of sound and various noise studies, and eventually combined the following sound types:

• White Noise: Renowned for its ability to mask background distractions, aiding concentration and sleep in noisy environments. Its steady sound helps settle the mind
• Pink Noise: Softer than white noise, with a more balanced tone. Research suggests it can improve sleep by gently slowing brainwave activity
• Brownian Noise: A deeper, richer sound reminiscent of thunder or distant waterfalls, often perceived as particularly soothing and grounding
• Green Noise: Incorporates natural elements like wind through trees or ocean waves, creating a peaceful and relaxing mental space

The Outcome‍

To validate the effectiveness of Calm Noise, we conducted user testing with 75 participants. Each user experienced a session with a loopable track, allowing us to measure real-world outcomes in mood improvement and stress relief.

Our results indicated that :

• Effectiveness: 89% found Calm Noise effective in reducing anxiety and aiding sleep
• Mood: 70% reported a moderate to strong uplift in mood compared to a general participant pool
• Emotion: 71% of participants experienced positive improvements

The success of the soundscape underscores its role in enhancing relaxation and well-being. We also created a pack of sleep soundscapes and Non-Sleep Deep Rest (NSDR) to complement Calm’s ideal bedtime routine.
