For a person with a conductive hearing loss (CHL) in quiet, the SRT needs to be higher than for a person with normal hearing. The increase in SRT depends on the degree of hearing loss only, so Factor A reflects the audiogram of that person. In noise, the person with a CHL has the same problem as the person with normal hearing (See Figure 10). [20]
Graph showing a typical Auditory Brainstem Response. The auditory brainstem response (ABR), also called brainstem evoked response audiometry (BERA) or brainstem auditory evoked potentials (BAEPs) or brainstem auditory evoked responses (BAERs) [1] [2] is an auditory evoked potential extracted from ongoing electrical activity in the brain and recorded via electrodes placed on the scalp.
Conditioned play audiometry (CPA) is a type of audiometry done in children from ages 2 to 5 years old, in developmental age. It is the test that directly follows visual reinforcement audiometry when the child becomes able to focus on a task. It is a type of behavioral hearing test, of which there are many.
A hearing test provides an evaluation of the sensitivity of a person's sense of hearing and is most often performed by an audiologist using an audiometer. An audiometer is used to determine a person's hearing sensitivity at different frequencies. There are other hearing tests as well, e.g., Weber test and Rinne test.
Audiogram. An audiogram is a graph that shows the audible threshold for standardized frequencies as measured by an audiometer.The Y axis represents intensity measured in decibels (dB) and the X axis represents frequency measured in hertz (Hz). [1]
Audiometry (from Latin audīre ' to hear ' and metria ' to measure ') is a branch of audiology and the science of measuring hearing acuity for variations in sound intensity and pitch and for tonal purity, involving thresholds and differing frequencies. [1]
Transcortical sensory aphasia is characterized as a fluent aphasia. Fluency is determined by direct qualitative observation of the patient’s speech to determine the length of spoken phrases, and is usually characterized by a normal or rapid rate; normal phrase length, rhythm, melody, and articulatory agility; and normal or paragrammatic speech.

Coronal section of a human brain. BA41(red) and BA42(green) are auditory cortex. BA22(yellow) is Brodmann area 22, HF(blue) is hippocampal formation and pSTG is posterior part of superior temporal gyrus. The auditory cortex is the part of the temporal lobe that processes auditory information in humans and many other vertebrates.
