For identification audiometry with school-age children, which type of signal is specifically recommended?

• A. Speech in quiet
• B. Pure-tone signals
• C. Speech in noise
• D. Frequency-modulated signals

Answer: (B)

For school-age children, the goal of identification audiometry is to determine basic hearing sensitivity across key frequencies in a simple, reliable way. Pure-tone signals fit this need because they are single-frequency sounds that can be precisely calibrated and presented at various standard frequencies. The child’s task is straightforward: indicate when they hear the tone. This yields clear, frequency-specific thresholds that align with conventional audiometry. Using speech in quiet or speech in noise shifts the task to how well the child understands speech, not just detectability of a sound, which is a different measure. Frequency-modulated signals add complexity and aren’t the standard for establishing basic thresholds. Therefore, pure-tone signals are the most appropriate choice for identifying hearing sensitivity in school-age children.
