A method exists for determining a single numerical representation of hearing sensitivity based on the results of an audiogram. This calculation, often performed with dedicated tools, uses thresholds obtained at specific frequenciestypically 500, 1000, and 2000 Hzto derive an average. For instance, if an individual’s hearing thresholds at these frequencies are 20 dB, 25 dB, and 30 dB respectively, the calculated value would be 25 dB.
This resulting value provides a convenient summary of hearing ability within the speech frequency range, which is critical for communication. Its utility lies in its ability to quickly classify the degree of hearing loss, track changes in hearing over time, and inform decisions regarding hearing rehabilitation options. Historically, this method has provided clinicians with a readily accessible and easily understandable overview of auditory function, supporting efficient patient management.
