After that point, people Definition of normal hearing: The range for normal hearing is defined as hearing thresholds of -10 to 15 dB at all frequencies (0 to 20 dB when testing babies through the speakers). Categories of hearing loss by severity: Slight hearing loss is defined as hearing thresholds in the range 20 to 25 dB. What is an audiogram? An audiogram is often called a “hearing test,” but there's no pass or fail.

A hearing test involves a number of steps and assessment procedures to find out your threshold of hearing (the softest sounds you can hear). The results of the audiometric assessment are plotted on an audiogram and compared to normal hearing levels. An audiogram is an inverted graph (upside down from most common graphs). The audiogram illustrates your hearing by representing your hearing threshold levels at different frequencies.
