What does NR stand for on a serial audiogram?

In the context of a serial audiogram, the abbreviation "NR" stands for "No Response." This term is used when a patient is tested for their hearing abilities but does not respond to specific sounds presented during the audiometric evaluation.

When "No Response" is indicated on an audiogram, it informs the audiologist or hearing health professional that the patient did not perceive any sound at the tested frequency and intensity levels. This could be due to several factors, including hearing loss, a lack of understanding of the test instructions, or the possibility of other conditions affecting the patient's ability to respond. By documenting "NR," the audiologist can take this into account when interpreting the results and making recommendations for further evaluation or management.

The other options are less accurate in this context. For example, "No Result" might suggest that the test was not completed or that there were procedural issues, while "Next Response" does not fit the standard terminology used in audiometric practice. "No Record" implies that there is no documentation of the test, which is also not the intended meaning in this specific scenario. Thus, recognizing "NR" as "No Response" is essential for accurately interpreting audiometric data.
