1. Relaxation and meditation: When using white noise for relaxation or meditation, the volume can be more of a personal preference. Generally, aim for a peaceful and soothing level, around 40-50 dB. This will vary depending on the individual's sensitivity and surrounding noises.
A noise level chart showing examples of sounds with dB levels ranging from 0 to 180 decibels. As a frame of reference, here are the decibel levels of sounds you may encounter in your everyday life. 0-30 dB, Very Faint. One-sixteenth as loud as 70 dB. Very Quiet.
Pink noise: Pink noise is white noise that's been filtered to have less energy in the higher frequencies—3 dB (decibels) per octave. It has less of a hiss than white noise, but isn't as toned down as brown noise.
Another reason why white noise promotes sleep lies in the nature of our brain: it thrives on stimulation. Nightly noises tend to activate our brain, disrupting our rest. A consistent white noise serves as a satisfying stimulus, preventing overexcitement when sudden sounds occur at night.
The threshold of human hearing is typically around 0 dB, while normal conversation levels usually fall within a range of 50-65 dB. When it comes to white noise, setting the volume between 50 and 70 dB is recommended for most users. The ideal dB level for white noise will vary depending on individual preferences and reactions to different volumes.
Different organizations suggest different volume levels for white noise depending on usage context. For example, the American Academy of Pediatrics (AAP) recommends a general maximum white noise volume of 50 A-weighted decibels (dBA), while the World Health Organization (WHO) suggests an even lower limit of 30 dBA for hospital nurseries.
Just for your information, noise at 70 dB level is similar to the sound of a moving car 10 meters away. Noise at this level was reported to be just soothing enough to calm our minds and keep ambient sounds away, with itself not being too overwhelming to distract us from our tasks .
Dangers of White Noise. The long-term safety of white noise is subject to debate. The American Tinnitus Association, for instance, states that noise exposure below 80 to 85 decibels is likely safe. Other experts say that white noise may harm the brain and central auditory system over time.
