Audiometry: What Does It Look Like and How Do I Interpret It? | An audiogram measures a patient's auditory threshold responses with pure-tone stimuli across a range of sound frequencies that are important for human communication, typically 250 Hz to 8000 Hz. The threshold is the sound intensity level at which an individual detects the tone 50% of the time. Heari... | Text |

What is the Cause of My Patient's Hearing Loss? | This is a flowsheet differentiating multiple causes of hearing loss. The onset and chronicity of hearing loss is a critical starting point in understanding whether urgent action is needed, such as in the setting of suspected stroke or sudden sensorineural hearing loss. For hearing loss that has been... | Text |
