What are spondees used for in SRT testing?

Spondees are specifically used in Speech Reception Threshold (SRT) testing as they consist of two syllables that are pronounced with equal stress. This characteristic makes them ideal for determining the lowest level at which a person can accurately repeat back words spoken to them, a critical component in assessing a person's hearing capabilities.

The choice of two-syllable words in SRT testing allows for a balanced measure of hearing sensitivity. Spondee words are usually familiar and commonly used, which helps ensure the test is effective and results are reliable. Utilizing one-syllable, three-syllable, or four-syllable words would not provide the same balance or clarity required for accurately gauging the threshold of hearing, making two-syllable spondees the preferred choice in this context.
