The link between speech-in-noise recognition and cognition has been researched extensively over the years, and the purpose of this thesis was to add to this field. Data from a sample of 394 participants from the n200 database (Rönnberg et al., 2016) was used to calculate the correlation between their performance on a speech-in-noise test and their score on a test measuring fluid intelligence. The speech-in-noise test consisted of matrix sentences with 4-talker babble as noise and fluid intelligence was represented by the score on a Raven’s Progressive Matrices test. Around half of the participants (n = 199) had documented hearing loss and were hearing aid users, while the rest were participants with normal hearing. The overall correlation between speech-in-noise recognition and fluid intelligence was -.317, which shows that a better (lower) score on the speech-in-noise test is correlated to a better score in the Raven’s test. The same type of correlation was calculated within the two different groups, and the results showed correlation of -.338 for the group without hearing loss and one of -.303 for the group with hearing loss. The results indicate that there is a weak to moderate correlation between speech-in-noise and fluid intelligence, and they support the theory that cognitive processing is related to speech perception in all people, regardless of hearing status.
