Why White Noise Can Trigger Trauma Problems: Understanding the Connection

Jan 23, 2024

White noise is a popular background sound for many individuals as it helps them to fall asleep, concentrate, or drown out other distractions. However, in certain cases, it can cause trauma-related problems for people with a history of traumatic experiences. But why does white noise cause trauma problems?

White noise is a combination of all audible frequencies at equal intensity. It is called white noise because it is analogous to white light, which is the combination of all colors of light at equal brightness. The constant buzzing of white noise can be soothing for most people, but for some, especially those with trauma histories, it can ignite trigger responses.

The Link Between White Noise and Trauma:
The connection between white noise and trauma-related issues can be traced to the similarities between the background noise and the sounds of traumatic experiences. White noise can include low-frequency sounds that may mimic the sounds of natural disasters, crashes, or explosions. This can cause people who have experienced such life-threatening incidents to revisit their traumatic memories and feel heightened anxiety or panic.

Sensitivity to Certain Sounds:
Hyperacusis, a condition characterized by an increased sensitivity to certain sounds, can occur in individuals who have experienced trauma. This heightened sensitivity may make the sounds associated with white noise particularly distressing, thereby causing trauma-related problems to surface.

Auditory Stimulus Filtering Issues:
Another possibility for the connection between white noise and trauma problems lies in the way our brains filter sensory stimuli. When experiencing trauma, our brains may have difficulty filtering out noises that would normally be ignored. This difficulty can persist long after the traumatic event and make sounds like white noise overstimulating and anxiety-provoking.

Possible Solutions:
If white noise is causing trauma-related issues in your life, it may be helpful to experiment with alternative background sounds. Many white noise machines offer a variety of options, such as nature sounds, gentle music, or soundscapes designed to mimic various environments. It may take some trial and error to find the most comforting and least triggering sound option.

In conclusion, the reason why white noise causes trauma-related problems for some people can be linked to the similarities between certain types of white noise and the sounds present during traumatic experiences. Those with trauma histories may also struggle with increased sound sensitivity or auditory stimulus filtering. As not every individual will react the same to white noise, it is essential to identify triggers and explore alternative background noises to find what works best for your personal comfort and well-being.
