Froemke says his team's latest findings reveal that while mammals recognize sounds in the auditory cortex of their brains, the signaling levels of nerve cells in this brain region are simultaneously being strengthened or weakened in response to surrounding context.

It may be that distractions deprive the errant signals from the auditory cortex of the attention they need to cause real distress.

Schlee's results suggest that the higher regions of the brain send their own feedback to the auditory cortex, amplifying its false signals.

This helps the signal processing within our auditory system to distinguish the voice of a singer as something quite different from the surrounding instrumentation of the orchestra.

The ability of the brain's visual timekeeper to override its auditory timekeeper probably reflects our brain's tendency to give more weight to signals that might represent a threat, according to Marc Wittmann, a time researcher at the University of California, San Diego, who was not involved in the study.

A previous study, published in 2013 in PLOS Biology by auditory neuroscientist Andrew King and his laboratory at the University of Oxford in England, showed that brain cells can enhance the gain of their responses, increasing the signal corresponding to the sound of interest, while tuning out the noise.

The cochlea has the all - important job of transforming mechanical energy in the form of sound waves into electrical signals that run along auditory nerves to the brain.

This set of cells is equivalent to the battery of the cochlea in that it provides hair cells with energy to transmit signals to the auditory nerve.

The perception of music starts with specialised hair cells in the inner ear, which transmit sounds as electronic signals through the auditory pathway to the auditory cortex, where sounds are primarily recognised.

It has demonstrated that physical changes in myelin itself - the coating of the auditory nerve carrying sound signals to the brain — affect our ability to hear.

To understand this evocative force, researchers in many fields, including information science, neural perception, and signal processing, investigate music's underlying structure, examining features such as the tone, timbre, and auditory and rhythmic features of a piece.
