English: "Journey of Sound to the Brain" – an animated explanatory video about the human hearing or auditory system. It illustrates how sounds travel to the inner ear, and then to the brain, where they are interpreted and understood. The cochlea in the inner ear is a spiral-shaped organ that contains hair cells, which sense sound vibrations ...
Damage to the auditory cortex in humans leads to a loss of any awareness of sound, but an ability to react reflexively to sounds remains as there is a great deal of subcortical processing in the auditory brainstem and midbrain. [13] [14] [15] Neurons in the auditory cortex are organized according to the frequency of sound to which they respond ...
The cause is thought to be thermoelastic expansion of portions of auditory apparatus, and the generally accepted mechanism is rapid (but minuscule, in the range of 10 −5 °C) heating of brain by each pulse, and the resulting pressure wave traveling through the skull to the cochlea. [5]
The fundamental function of this part of the ear is to gather sound energy and deliver it to the eardrum. Resonances of the external ear selectively boost sound pressure with frequency in the range 2–5 kHz. [2] The pinna as a result of its asymmetrical structure is able to provide further cues about the elevation from which the sound originated.
In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. [1]

The cells of lower auditory pathways are specialized to analyze physical sound parameters. [3] Summation is observed when the loudness of a sound from one stimulus is perceived as having been doubled when heard by both ears instead of only one. This process of summation is called binaural summation and is the result of different acoustics at ...
