What is the abbreviation for the left ear?

The abbreviation for the left ear is "AS," which stands for "auris sinistra" in Latin. This term is commonly used in audiology and medical fields to indicate the left ear specifically in various contexts, such as hearing tests and prescriptions for hearing aids.

Understanding the use of this abbreviation is essential for healthcare professionals in accurately documenting and communicating about a patient's auditory health, as well as ensuring precise fitting and adjustment of hearing devices tailored for each ear. In contrast, the other options do not have a recognized association with the left ear; they could represent different terms or concepts unrelated to ear designations.
