What factors affect the perception of tone height?
As soon as the sound enters the ears, it is processed by the physical components of the middle and inner ear and the hearing centers of the brain. The perception of the climb is influenced by several factors, including the nature of how the sound in the body is processed. Neural coding in the brain affects how people hear sound. The presence of multiple sounds, volume changes, or the frequency of sound pulses can affect how the playground is perceived. Theories that have tried to define the perception of tone height include the theory of place and time theory.
The sound enters the ear and is first processed with a ear drum or a tympanic membrane. It then translates into three small bones movements before it goes to Kochle, a spiral organ in the inner ear with hair cells that move with sound waves. The movement of the hair is translated into signals that pass into the auditory nerve. Different frequencies are picked up by different parts of the basilar membranes inside Kochle, as explained according to the theory of the place. This theory also describes how high harmonious,that are close to each other are not perceived as separate.
Theorists also speculated that the sound is perceived in relation to time known as time theory. Nerve cells shoot at periodic time intervals, but also serve to analyze frequency. The combination of both theories helps to explore the nature of sound perception in humans. The neural activity in the auditory cortex has a deep effect on the perception of the height of the tone, while the change of pitch stimulates the areas on the right hemisphere. Problems in the right time areas of the brain sometimes affect how someone is able to detect changes in tone height.
The inability to understand the change of tone is part of the fact that the tone is the deaf. When the melodies are converted to different keys, the relative pitch of each note is generally perceived. The sound intensity also affects the perception of the climb. Increasing the intensity for high phzvuky requirements will cause them to sound as if they rise. Increasing the intensity of sounds with low FreFlower causes it to sound as if the pitch decreased.
The sounds that pulsate or maintain have a different perception of tone height. Ve srovnání se stabilním pulsem se zdá, že zvukové impulsy s klesající amplitudou mají vyšší rozteč. Noise and tones that are heard over one tone can also change its apparent playground. The perception of the playground is therefore influenced by internal and external factors. It seems that the sound that remains stable sometimes seems to be changing as the human ear hears.
