For identification audiometry in school-age children, which type of signal should be used?

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

Answer: (D)

The main idea is that identification audiometry aims to determine basic, frequency-specific hearing thresholds using a simple behavioral task. For school-age children, the standard approach is to present pure-tone stimuli because they are the most straightforward and reliable way to measure whether a child can detect sounds at specific frequencies. Pure tones are easy to control for frequency and intensity, allowing the audiologist to build a clear audiogram across the usual frequencies (250 Hz to 8 kHz). Speech stimuli, while useful for assessing how well a child understands spoken words, are not ideal for identifying pure-tone thresholds because they involve language processing and memory and don’t provide clean, frequency-specific threshold data. Speech-in-noise tests examine perception in noisy environments rather than basic detection. Frequency-modulated signals aren’t the typical choice for establishing simple, threshold-level audiometry, as they’re used for more specialized purposes and can complicate threshold estimation. Pure-tone signals stay the standard because they yield the most direct measure of the child’s auditory sensitivity across frequencies.
