Deep dives
The Impact of Sound on Our Lives
Sound has a profound effect on our lives. It can connect us, evoke emotions, and even shape our brains. When we listen to music or hear certain sounds, our brain releases dopamine, which influences how we feel. The brain is constantly trying to make sense of the sounds it hears and find patterns within them. This explains why certain sounds, like dissonant chords in music, can initially make us feel uncomfortable. However, with repeated exposure, our brain can adapt and begin to appreciate and even enjoy those sounds. This highlights the brain's remarkable ability to process and interpret new and unfamiliar auditory stimuli.
The Influence of Language Melodies on Infants
Researchers have found that there are universal melodies in language that communicate specific messages to infants. For example, parents across different languages use similar melodies to praise, stop, call attention to, and comfort their babies. These melodies are deeply ingrained in our brains from a young age, and they help infants understand and interpret the meaning behind the language. This suggests that there is a deep connection between language and music, as both rely on melodic patterns to convey emotions and information. By studying these melodies, scientists hope to uncover more about the ways in which our brains process and respond to auditory stimuli.
The Brain's Response to New and Unfamiliar Sounds
When our brains encounter new and unfamiliar sounds, they go through a process of trying to understand and make sense of them. Neurons in the auditory cortex, the part of the brain responsible for processing sound, work to analyze and decipher the patterns within these unfamiliar sounds. This process can lead to fluctuations in brain activity and the release of dopamine, a neurotransmitter associated with pleasure and emotion. If the neurons are successful in finding patterns within the new sounds, we begin to appreciate and enjoy the music or auditory experience. However, if they struggle to find order in the chaos, it can lead to discomfort or even a sense of unease.
The Malleability of Musical Perception
Our perception of music is not fixed and can be influenced by various factors, including cultural context, prior exposure, and individual preferences. What may initially sound dissonant and unpleasant to one person may become enjoyable and familiar to another after repeated exposure and adaptation of the auditory system. The brain has a remarkable ability to tune and adjust its neural networks to make sense of different sounds, allowing us to develop a deeper appreciation for music that was once perceived as challenging or unconventional. This highlights the dynamic interplay between the brain, culture, and personal experiences in shaping our musical preferences.
In this episode from 2007, we take you on a tour of language, music, and the properties of sound. We look at what sound does to our bodies, our brains, our feelings… and we go back to the reason we at Radiolab tell you stories the way we do.
First, we look at Diana Deutsch’s work on language and music, and how certain languages seem to promote musicality in humans. Then we meet Psychologist Anne Fernald and listen to parents as they talk to their babies across languages and cultures. Last, we go to 1913 Paris and sneak into the premiere of Igor Stravinsky’s score of The Rite of Spring.

The performance that inspired rioting occurred on May 29th, 1913. The second performance that we discussed occurred in April of 1914. The audio has been adjusted to reflect this fact.Correction: An earlier version of this piece incorrectly stated that the “Rite of Spring” was used in the movie “Fantasia” during the part that featured mushrooms. It was in fact used during the part that featured dinosaurs. The audio has been adjusted to reflect this fact.
