Masking threshold within acoustics (a branch of physics that deals with topics such as vibration, sound, ultrasound, and infrasound), refers to a process where if there are two concurrent sounds and one sound is louder than the other, a person may be unable to hear the soft sound because it is masked by the louder sound.
Here's how to read an audiogram and a doctor's explanation of the most common results including sloping hearing loss, notched hearing loss, cookie-bite hearing loss and reverse-sloping hearing loss.
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 ]
The results are represented by an audiogram, and are usually interpreted by an audiologist, or a registered Medical Officer, [4] unless the audiometrist is also an audiologist, with the aim of diagnosing hearing loss.

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.
