<reasoning>

Identify the core question

The question asks for the required frequency of calibration for audiometers.

Analyze clinical standards

Using the Clinical Audiometry knowledge point, we recall standard clinical protocols. According to national and international standards (such as ANSI S3.6), formal electroacoustic calibration of audiometers must be performed at least once a year.

Differentiate calibration types

While biological or functional checks are performed daily, formal electroacoustic calibration must be completed annually to ensure accuracy and compliance.
