White noise is a type of sound that contains all the frequencies of the audible spectrum, played at equal intensity. It is often used to mask other sounds, promote relaxation, and improve sleep quality. However, some people have reported hearing strange and sometimes disturbing sounds when exposed to white noise. This phenomenon is known as “ghosting” or “stochastic resonance”. In this article, we will explore why some people hear things in white noise and what causes this unusual experience.

Why do I hear things in White Noise?

What is White Noise?

White noise is a type of sound that contains all frequencies in the audible range, with each frequency having equal intensity. This creates a sound that is often described as a “static” or “hissing” noise. It is called “white” noise because it is analogous to white light, which contains all visible colors at equal intensity.

White noise is commonly used as a masking sound to block out unwanted noise or to promote relaxation and sleep. It can also be used to test audio equipment, as any irregularities in sound reproduction will be more noticeable when playing white noise. In addition, white noise has been used in research to investigate a range of topics, from auditory perception to cognitive neuroscience.

What is Ghosting in White Noise?

Ghosting, also known as stochastic resonance, is a phenomenon where the brain perceives faint sounds or patterns in a noisy environment. This can cause a person to hear sounds that are not present in the original signal, such as voices, music, or even animal noises. Ghosting is a common experience for some people who are exposed to white noise.

The phenomenon of ghosting is not limited to white noise. It can occur in any type of noisy environment, such as a crowded room, a waterfall, or even the sound of rain. The reason why some people experience ghosting in white noise is still not fully understood, but researchers believe it may be related to the brain’s auditory processing system.

Why do Some People Hear Things in White Noise?

There are several theories about why some people experience ghosting in white noise. One theory is that the brain is constantly searching for patterns and meaning in the environment. When exposed to white noise, the brain may try to make sense of the sound by creating patterns and filling in gaps in the noise. This can result in the perception of sounds that are not present in the original signal.

Another theory is that the brain’s auditory system is sensitive to low-level sounds and is able to detect faint patterns in the white noise. These patterns may be interpreted as meaningful sounds by the brain, resulting in the perception of ghosting.

Additionally, some researchers have suggested that the experience of ghosting in white noise may be related to individual differences in brain activity and sensitivity to sensory stimuli. People who are more sensitive to sensory stimuli may be more likely to experience ghosting in white noise.

How Can Ghosting in White Noise be Reduced?

If you experience ghosting in white noise and find it bothersome, there are several strategies that may help reduce the phenomenon. One strategy is to reduce the volume of the white noise or switch to a different type of masking sound, such as pink noise or brown noise. These types of sounds are similar to white noise but have different frequency distributions, which may reduce the likelihood of ghosting.

Another strategy is to use noise-cancelling headphones or earplugs to reduce the amount of external noise that may be contributing to ghosting. This can help create a quieter environment and reduce the brain’s tendency to fill in gaps in the noise.

Finally, some people find that using a different type of sound therapy, such as guided meditation or music therapy, can be more effective for promoting relaxation and reducing stress than white noise alone.

The Science Behind White Noise

Before we can understand why we might hear things in white noise, it’s important to first understand the science behind this type of sound. White noise is created by combining sounds of different frequencies, all of which are played at equal intensities. The result is a sound that has a constant and uniform distribution of energy across all frequencies.

One of the key properties of white noise is that it contains a lot of random variations in amplitude and frequency. This randomness can make it difficult for our brains to distinguish specific sounds, which is why it is often used to mask other sounds in our environment.

However, the randomness of white noise can also be responsible for the perception of strange or unsettling noises. When we listen to white noise, our brains are constantly trying to make sense of the sounds we hear. This can sometimes lead to our brains creating patterns where there are none, resulting in the perception of sounds that aren’t actually there.


In conclusion, the experience of hearing things in white noise can be perplexing and even frightening. However, there are many explanations for why this phenomenon occurs, and it is generally not a cause for alarm. While some people may have underlying conditions that contribute to their experience, such as tinnitus or hearing loss, for most people, it is simply a natural result of the brain’s tendency to create patterns and associations.

It is important to remember that each person’s experience is unique, and there is no one-size-fits-all explanation for why people hear things in white noise. By understanding the various factors that can contribute to this experience, individuals can make informed decisions about how to approach it and what steps, if any, to take to alleviate any discomfort or anxiety.

Ultimately, the human brain is a complex and remarkable organ, capable of interpreting a wide range of sensory input and generating a wealth of perceptions and experiences. While hearing things in white noise may seem strange or unsettling at first, it is simply one more example of the amazing capabilities of the human mind.
