Which frequency is NOT generated by an audiometer?

An audiometer is an instrument used to measure hearing sensitivity at various frequencies, typically within the range of human hearing. The frequencies commonly generated by audiometers include 250 Hz, 500 Hz, and 1000 Hz, which are standard testing frequencies used in audiometric evaluations to assess a person's hearing ability across low to mid-frequency sounds.

The correct response indicates that 800 Hz is not a standard frequency generated by an audiometer. While many audiometers have the capability to generate a wide range of frequencies, they usually focus on the most clinically relevant frequencies for assessing hearing. The standard frequencies often revolve around octave intervals (such as 250 Hz, 500 Hz, 1000 Hz, and so forth) and are chosen for their significance in speech perception and auditory testing protocols. As such, frequencies like 800 Hz may not be prioritized or used as regularly in clinical practice, which accounts for its selection as the answer in this context.

This selection highlights the importance of knowing which frequencies are relevant and standard in audiometric testing, helping clinicians ensure effective assessment of hearing acuity within established norms.
