What is an Audiogram?
An audiogram is a visual representation of an individual's hearing abilities across various frequencies. It is typically produced through a hearing test conducted by an audiologist or hearing specialist, which assesses the softest sounds a person can hear at different pitches.
How is an Audiogram Created?
The process begins with the patient wearing headphones connected to an audiometer. The audiologist plays specific tones at varying volumes and frequencies. The patient indicates when they can hear a sound, allowing the audiologist to map the results on a graph.
Interpreting the Audiogram
An audiogram displays frequency on the horizontal axis (measured in Hertz) and hearing sensitivity on the vertical axis (measured in Decibels). The resulting points are connected to form a curve. Normal hearing typically falls between 0 to 20 dB across frequencies, while higher thresholds indicate varying degrees of hearing loss.
Importance of Audiograms
Audiograms are essential for identifying hearing impairments early. They guide treatment options such as hearing aids or therapy and serve as references for tracking changes in hearing over time. Regular screening through audiograms can significantly enhance preventive care for hearing health.
