How Semantic Context Affects Hearing Speech in Noise: A Look at the QuickSIN Test

What is it about?

When people listen in noisy places, like a crowded restaurant, they do not solely rely on hearing each word clearly. They also use context clues, the meaning of the sentence as a whole, to fill in the gaps. For example, if you hear “I put sugar in my ___,” you can probably guess the missing word is “coffee,” even if the last word was hard to hear. This study examined how much people rely on context clues when taking a common speech-in-noise perception clinical test called the Quick Speech-in-Noise Test (QuickSIN). By designing a new way to measure how people use sentence meaning, this study helps us see whether the test measures just hearing ability, or also language processing.

Why is it important?

Difficulty hearing speech in the presence of background noise is a common patient complaint in the audiology clinic. Often audiologists will administer a speech-in-noise perception test, such as the QuickSIN, to get an idea of how well a patient hears in the presence of background noise. The QuickSIN test has patients repeat back sentences they hear in different amounts of competing noise. How people use language context will affect their performance on this test. This means that results might be influenced by language ability, not solely hearing ability. Our findings suggest that speech-in-noise tests should make sure the sentences are more balanced in how much context they provide, so the test reflects listening ability more accurately.
