“Technological Advances in Music and its effects”
In the early years of music, musicians performed on stage with live bands and orchestras to the locals in the community. Their music consisted of many harmonies and rhythms that would relax the mind and ease stress. Their classical style of music had more of a string type sound, in comparison to the rough and rugged sounds of today’s music. Did this rough music affect the way we hear things compared to their classical harmonic sounds? What technological advances in musical devices have caused these effects if there are any? Does music now affect the way we live compared to the music of the past? Back in the day people had no means of carrying around music as portable

Results cause displacement which creates synchronized waves in the endolymph within cochlear duct (Seeley, Stevens, & Tate, 2002). Longer waves generate low pitches, while shorter waves produce high pitches. Stimulations occur along the basilar membrane. Hairs cells sitting on the basilar membrane become distorted much like a string instrument. Cells bound to the basilar membrane move in conjunction with the tectorial membrane. Stereocillia embedded within the tectorial membrane then become bent. After microvilli bend, hairs cell depolarize (Seeley, Stevens, & Tate, 2002). Since hair cells do not have axons, action potentials are induced in the cochlear neurons. Signals are carried by afferent neurons bond to form the cochlear nerve. This combines with the vestibular nerve to construct the 8th cranial nerve. Finally, it carries action potentials to the brain where they are translated in the cerebral cortex as sound (Seeley, Stevens, & Tate, 2002). Interference within any stage of this process can result in hearing loss or damage. Diagrams 1. and 2. below, help illustrate the process the hearing.
