The auditory system is the sensory system for the sense of hearing. ... Anatomy of the human ear (The length of the auditory canal is exaggerated in this image.).
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).
The human auditory system is truly a remarkable and complex sense that is still being studied and understood. Conclusion. In conclusion, the human auditory system is a marvel of biological ...
The human auditory system has only limited possibilities to determine the distance of a sound source. In the close-up-range there are some indications for distance determination, such as extreme level differences (e.g. when whispering into one ear) or specific pinna (the visible part of the ear) resonances in the close-up range.
The human auditory system is most sensitive to frequencies between 2,000 and 5,000 Hz. [10] Individual hearing range varies according to the general condition of a human's ears and nervous system. The range shrinks during life, [11] usually beginning at around the age of eight with the upper frequency limit being reduced. Women lose their ...
Sounds outside this range are considered infrasound (below 20 Hz) [14] or ultrasound (above 20 kHz) [15] Although hearing requires an intact and functioning auditory portion of the central nervous system as well as a working ear, human deafness (extreme insensitivity to sound) most commonly occurs because of abnormalities of the inner ear ...
The human auditory system is sensitive to frequencies from about 20 Hz to a maximum of around 20,000 Hz, although the upper hearing limit decreases with age. Within this range, the human ear is most sensitive between 2 and 5 kHz, largely due to the resonance of the ear canal and the transfer function of the ossicles of the middle ear.
The auditory cortex is composed of fields that differ from each other in both structure and function. [19] The number of fields varies in different species, from as few as 2 in rodents to as many as 15 in the rhesus monkey. The number, location, and organization of fields in the human auditory cortex are not known at this time.
