An otoacoustic emission (OAE) is a sound which is generated from within the inner ear. Studies have shown that OAEs disappear after the inner ear has been damaged, so OAEs are often used in the laboratory and the clinic as a measure of inner ear health. Videonystagmography (VNG) is a technology for testing inner ear and central motor functions, a process known as vestibular assessment. Dichotic listening is a psychological test commonly used to investigate selective attention within the auditory system and is a subtopic of cognitive psychology and neuroscience. Latest audiology diagnostic tools include Diagnostic Audiometer, canal symposiums which can easily perform routine air and bone conduction threshold audiometry, but it also comes with portable application as well.
