Inclusion criteria

Inclusion criteria: Aged 18 years or older Native speaker of the Dutch language Normal hearing (hearing thresholds of 20 dB hearing level or better for all octave frequencies between 250 and 8000 Hz) or sensorineural noise-induced hearing loss (one or more hearing threshold levels at 2-6 kHz >25 dB HL)

Exclusion criteria

Design outcomes

Primary

Measure	Time frame
Part 1: Test results (SRT scores) of the speech-in-noise tests in the various conditions will be compared between normal hearing and hearing impaired subjects, in order to accurately implement the test for the occupational practice. Part 2: The results of the test performed at work will be compared with the results of the standard pure-tone audiogram of a large group of construction employees, to assess the sensitivity and the specificity of the speech-in-noise test in this specific population.	—

Secondary

Measure	Time frame
Part 1 and 2: Differences in SRT score between test and retest, the amount of correlation between SRT scores of test and retest, and the intra-individual standard deviation of the difference will be studied, in order to estimate the test-retest reliability and the learning effect. Part 2: The difference in mean SRT score between the first measurement and the follow-up will be studied. For the follow-up, test results will also be compared with standard pure-tone audiogram.	—
