In humans and other vertebrates, hearing is performed primarily by the auditory system: mechanical waves, known as vibrations, are detected by the ear and transduced into nerve impulses that are perceived by the brain (primarily in the temporal lobe). Like touch, audition requires sensitivity to the movement of molecules in the world outside the organism.There are three main sections of our hearing system: the outer ear, the middle ear, and the inner ear (please see image above). Each section of the ear plays a role in the way we perceive sound.The authors of the research, an Italian-Australian collaboration, have also demonstrated that cyclicity also concerns the listener’s ability to classify a sound, in this case with much faster oscillations, proving how our decisions and perceptive abilities use different circuits and are regulated by different rhythmsAccording to the study, the rhythmic sampling of sensory information reflects the action of attention: when looking at a scene, some parts receive more attention than others, and these areanalysed with priority, based on an effective strategy that focuses resources on specific objects of interest.
As a side note: Omg earphone users.
when you grow older the hearing sensitivities at high frequencies are severely reduced, and even the 6 kHz range is severely affected in the elderly
Simple concept of perceive sound.
Sound is produced when the chords of a guitar are set in vibration .This vibratory movement then propagates in the form of waves, like the waves that arise when a stone falls in water . Waves can travel only in a medium such as water or air , but the vacuum is completely silent. sound waves compress the air. Sometimes sound compresses the air so strongly that it causes pain in the eardrum because of the high pressure of the waves.Very deep sounds propagate into the ground, and our body feels vibrations.
