Where are thresholds recorded on an audiogram?

Thresholds on an audiogram are recorded to assess a person's hearing sensitivity across different frequencies. The correct option highlights that thresholds are indicated in terms of frequency, which is measured in Hertz (Hz), and intensity, often depicted in decibels (dB).

The frequency component allows audiologists to understand at which pitches a person can hear sounds, while the intensity component indicates how loud the sounds need to be for the individual to detect them. This is crucial for identifying any hearing loss and tailoring hearing aids or other interventions appropriately.

In this context, frequency and intensity provide a comprehensive view of an individual's hearing capability, making it essential for the proper diagnosis and treatment of hearing-related issues.
