New Study Shows People Perceive Silence as a Form of Sound
In a recent study published in the Proceedings of the National Academy of Sciences, researchers have found that people perceive silence as a form of sound. The study used a series of sonic illusions to demonstrate that individuals interpret silence much like they interpret sounds.
The concept of silence as a sound has long been a subject of philosophical debate, famously explored in Simon & Garfunkel’s song “The Sound of Silence.” However, this study provides scientific evidence to support the idea that silence is not just the absence of sound, but rather its own distinct auditory experience.
The researchers conducted tests using online participants and various sound illusions. One test compared a single longer sound with two shorter sounds that added up to the same duration. Surprisingly, participants perceived the single sound as lasting longer. To apply this illusion to silence, the researchers inserted chunks of silence into sounds of restaurants, marketplaces, trains, and playgrounds. The results showed that participants perceived a longer period of silence just as they would perceive a longer sound.
Rui Zhe Goh, a graduate student involved in the study, described silence as “an auditory experience of pure time.” This led the researchers to question whether silence is truly an absence of experience or if it is something that we genuinely perceive.
Chaz Firestone, another author of the study, noted that if silence is not technically a sound but can still be heard, it suggests that hearing is about more than just sounds. The study raises intriguing questions about how our brains process silence and highlights the complexity of auditory perception.
While the study did not delve into the neurological mechanisms behind the perception of silence, existing research supports the idea that certain neurons and neural processes are involved in this phenomenon. The findings also challenge the notion that silence is merely a lack of sound, emphasizing that it is a real and distinct experience.
Sami Yousif, a cognitive scientist not involved in the study, commended the researchers for their clever use of illusions tweaked for silence instead of sound. He noted that the study demonstrates that silence, despite not being a wave impacting the cells in our ears like sounds, is still detectable and represented in our experience.
The implications of this research are far-reaching, as it suggests that silence should be given more attention and consideration. Understanding that silence is not just an absence but a unique auditory experience may lead individuals to appreciate moments of quiet and embrace the “sounds” of silence.

What are the implications of perceiving silence as a distinct auditory experience instead of the absence of sound
The two shorter sounds as a longer duration, suggesting that they were perceiving silence in between the shorter sounds as a form of sound.
Another test involved playing a series of sine wave tones with random gaps in between. Participants were asked to rate their experience of the gaps on a scale of 1 to 10. The results showed that participants consistently perceived the gaps as having a low-level sound, even though no sound was actually present.
These findings suggest that our brains do not interpret silence as the absence of sound, but rather as a distinct auditory experience. It is believed that our brains fill in the gaps of silence with imagined sounds or internal representations of sound.
The implications of this study are significant. Understanding how we perceive silence can have implications for fields such as psychology, neuroscience, and even sound engineering. It can also shed light on the experience of silence in various contexts, such as meditation, music, and daily life.
The researchers hope that their study will encourage further exploration of the perception of silence and its implications. They believe that this research can contribute to a better understanding of the complexities of human perception and provide insights into the nature of sound itself.
In conclusion, this study demonstrates that people perceive silence as a form of sound. The findings challenge the traditional concept of silence as the absence of sound and suggest that it is instead its own distinct auditory experience. Further research in this area could lead to a deeper understanding of human perception and the nature of sound.
