When should an audiogram baseline not be re-established by a technician?

The correct answer is when bilateral, flat hearing loss is suspected. In situations where a bilateral, flat hearing loss is present, the typical pattern does not provide a clear distinction that would necessitate re-establishing a baseline audiogram. A flat hearing loss characteristically affects both ears similarly, meaning that establishing a new baseline may not be warranted, as it could complicate tracking changes over time.

Determining when to re-establish a baseline relies heavily on the patterns and characteristics of the hearing loss observed. For instance, when symmetric hearing loss or unilateral hearing loss is indicated, the technician may need to assess the situation more closely and potentially re-establish a baseline to monitor auditory changes effectively. Additionally, confirming normal hearing typically suggests that a baseline may not need to be re-established unless there are subsequent changes that warrant review.
