What does the use of a manual audiometer typically require compared to a microprocessor audiometer?

The use of a manual audiometer typically requires more time and effort for testing compared to a microprocessor audiometer. Manual audiometers generally involve a hands-on process where the operator must carefully control the testing parameters, such as adjusting the frequency and intensity of sounds, and interpreting the results on their own. This can make the testing process more time-consuming, as each step must be performed manually, and the operator needs to be attentive at all stages.

In contrast, microprocessor audiometers are designed to automate many of these functions, often providing more efficient testing through automated sequences and integrated data management. They can streamline the process, thus requiring less time and effort from the technician. This comparison highlights the operational differences between the two types of audiometers in terms of efficiency and workload involved in hearing conservation testing.
