The most dangerous voices incite dancing and science searches for reasons – Science

Science Writing, November 7 (EFE). Low-frequency bass sounds make people dance more, specifically 11.8% more, according to a study conducted during a live electronic concert.

Research published Monday by Current Biology examined body movements during a concert and concluded that when bass levels are introduced through speakers too low to be heard, people dance more.

Study lead author Daniel Cameron of McMaster University in Canada has focused his career on the rhythmic aspects of music and how it gets us moving.

“Music is a biological curiosity: it does not reproduce from us, it does not nourish us and it does not warm us, so why do humans like it and why do they like to move with it?” statement.

Created at McMaster University, LiveLab is equipped with a 3D motion capture and sound system that can reproduce different concert environments and speakers optimized to produce frequencies too low to be detected by the human ear.

The team recruited participants to a concert by electronic music duo Orphx and were provided with motion-sensitive headbands to monitor their dance movements.

During the 45-minute concert, the researchers manipulated the ultra-low speakers, turning them on and off every two minutes. They found that the amount of movement was 11.8% higher when they were on.

“The musicians were excited to participate because of their interest in the idea that bass could change the way music is experienced in a way that affects movement,” Cameron said.

The sense of vibration through touch and the interactions between the inner ear and the brain have close links with the motor system.

The researchers speculate that these physical processes are involved in the neural connection between music and movement. This anatomy can pick up low frequencies and can affect spontaneous movement and perception of rhythm.

The researcher added, “Very low frequencies can also affect vestibular sensitivity, increasing people’s experience of movement. To identify the brain mechanisms involved, it will be necessary to study the effects of low frequencies on the vestibular, tactile and auditory pathways.”
