Sound has been used in all cultures throughout history for various purposes such as eliciting positive emotional states during celebrations, inducing altered states of consciousness during trance-like experiences, and adding depth of emotion to performances. The brain is constantly transmitting data between regions through brain waves in a similar way to Wi-Fi. Some of these signals come from within the body while others are environmental stimuli, though the brain cannot distinguish the difference. Neuroscience techniques such as brain-computer interfaces and electroencephalography can provide insights into how sound and other stimuli impact brain activity and performance.
