What is an audiogram?

An audiogram is fundamentally a graph that visually represents the results of a hearing test. It displays an individual's hearing sensitivity across a range of frequencies, typically measured in Hertz (Hz). The audiogram indicates how well a person can hear various pitches and volumes, allowing hearing healthcare professionals to easily assess hearing ability and identify hearing loss. The horizontal axis of the audiogram usually represents frequency, while the vertical axis indicates the intensity of sound in decibels (dB).

By interpreting the audiogram, clinicians can determine the type and degree of hearing loss, which is essential for making informed decisions about appropriate interventions, including hearing aid selection and fitting. This makes option B the correct answer, as it accurately depicts the purpose and format of an audiogram in audiology.
