In children, early diagnosis and treatment of impaired auditory system function is an important factor in ensuring that key social, academic and speech/language developmental milestones are met. [43] Impairment of the auditory system can include any of the following: Auditory brainstem response and ABR audiometry test for newborn hearing
Hearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium. [1] The academic field concerned with hearing is auditory science .
Otoacoustic emissions test is an objective hearing test that may be administered to toddlers and children too young to cooperate in a conventional hearing test. Auditory brainstem response testing is an electrophysiological test used to test for hearing deficits caused by pathology within the ear, the cochlear nerve and also within the brainstem.
There is a greater opportunity to hear a sound depending on the location of electrodes compared to the tissue and the number of remaining neurons located in the auditory system. [19] In addition, individual capacities, as well as the neural supply to the cochlea, play a role in the process of learning with cochlear implantation.
Auditory feedback (AF) is an aid used by humans to control speech production and singing by helping the individual verify whether the current production of speech or singing is in accordance with his acoustic-auditory intention. This process is possible through what is known as the auditory feedback loop, a three-part cycle that allows ...
Many children with implants often continue to struggle in a spoken-language-only environment, even when support is given. [29] Children who received cochlear implants before twelve months old were significantly more likely to perform at age-level standards for spoken language than children who received implants later.
There is a strong association between the cerebral cortex and auditory function. Animal studies have shown that extirpation of the auditosensory cortex leads to the loss of responsiveness to previously learnt tones. [16] The locations of auditory cortical neurones and conformations of the primary auditory cortex are unique to every individual.
The auditory detection threshold for AM as a function of AM rate, referred to as the temporal modulation transfer function (TMTF), [49] is best for AM rates in the range from 4 – 150 Hz and worsens outside that range [49] [50] [51] The cutoff frequency of the TMTF gives an estimate of temporal acuity (temporal resolution) for the auditory ...
