Auditory perception is the ability to perceive and understand sounds, which is important for speech and language. The brain is responsible for transforming noise into something useful and understandable. Hearing impairment can affect auditory discrimination, synthesis, and sequencing, and can be detected in children who do not understand or respond to auditory cues.
Auditory perception is the ability to perceive and understand sounds, usually with specific organs, such as a human’s ears. Sound exists in the form of vibrations that travel through the air or through other substances. The ears detect these vibrations and convert them into nerve impulses, which are then sent to the brain where they can be interpreted. Deafness describes a condition in which individuals lack auditory perception; deaf people are unable to perceive or interpret sounds. Different animals can perceive different sounds; dogs, for example, are able to perceive very high-pitched sounds that humans cannot perceive.
There are many factors that influence auditory perception beyond just hearing sounds. The brain is largely responsible for many processes that can transform an incoming mass of noise into something useful and understandable. Auditory discrimination is the process by which differences between sounds can be noticed; this is extremely important for speech as spoken words are understood based on different sounds. Discrimination between foreground and background is also an important part of auditory discrimination. It’s important to be able to focus on the important noises and ignore the irrelevant and unimportant noises so you don’t get overwhelmed by a large amount of noise.
Auditory synthesis is another very important process for understanding language. It describes the process by which the brain combines different sounds into understandable units, similar to the way letters are combined into words and words into sentences. Auditory sequencing is a process closely related to both memory and auditory perception. Describes the ability to understand and remember the order in which certain sounds occurred.
Individuals who are hearing impaired may simply have difficulty hearing low sounds or extreme pitches. They can also, however, have problems with the above processes that are essential for making sense of sounds. Problems with auditory perception can exist from birth or can be caused by injury to the brain or ears. They are generally easy to detect; one with hearing impairment either cannot hear well or cannot make sense of the sounds they hear.
Some children suffer from an auditory perception loss from birth. There are many ways to detect hearing problems in children. They often do not understand or respond to auditory cues or commands. They ask for directions to be repeated, often several times. In many cases, they look at what others are doing before taking any action.
