Audiograms and functional auditory testing to assess hearing speech in noise

17 Aug 2015

Pure-tone audiometry is most commonly used to assess hearing, and involves the administration of pure-tones at different intensities and frequencies to assess the softest sound audible to the individual.1,2 An audiogram is then created based on the results of the audiometry to examine the hearing level in decibels (dB) at the different frequencies tested, measured in hertz (Hz).2 Individual result [...] Each of these tests involves the participants listening to words or sentences with background noise present, to assess the ability of the participant to hear the words or sentences being spoken.1 Further detail on each of these tests is available in Appendix 1. The purpose of this Rapid Response report is to review the effectiveness of audiograms and functional auditory tests for assessing the abi [...] The performance of the WIN and the Speech Recognition in Noise Test (SPRINT) were found to be similar in one study, and the WIN was found to be a more sensitive measure of speech-in-noise relative to the HINT in another study. [...] Only one study reported proportion of males and females in the study population.7 In addition, investigators were not blinded to the tests in any of the included studies, and it is unclear if it was the investigators actually administering the tests and calculating the scores for each participant.4-7 This is of particular concern relating to the studies assessing the WIN because the first author o [...] One study compared the SPRINT to the WIN,6 and the second compared the HINT to the WIN.7 The SPRINT was compared to the WIN in 72 people, 24 of which were young listeners with normal hearing (defined as 20 dB HL at the 250 – 8000 Hz octave intervals on audiogram), and 48 of which were older individuals (60 to 85 years of age) with hearing loss.6 Hearing loss was defined as audiogram thresholds o
