What is an audiogram?

An audiogram is indeed a graphic representation of an individual's hearing ability. This visual tool displays the results of a hearing test, where the threshold of hearing for various frequencies is plotted on a chart. The x-axis represents frequency (measured in Hertz), while the y-axis shows hearing sensitivity (measured in decibels).

The audiogram allows clinicians to assess the degree of hearing loss and understand how well an individual can hear different pitches. By looking at the patterns on the audiogram, audiologists can diagnose hearing impairments and determine appropriate interventions or hearing conservation strategies. This makes it an essential component in occupational hearing conservation programs.

The other options refer to different elements associated with hearing but do not accurately describe what an audiogram is. Understanding audiograms is crucial for those involved in occupational health to ensure effective monitoring of employees' hearing capabilities over time.
