Noisy workplace and music exposure: objective and subjective effects on hearing.

Objective (SRT): General linear modelling of better ear speech reception threshold (dB) based on number of years workplace noise exposure relative to no exposure. Factor: Main effect for noise/music exposure. Sex: Interaction with gender. The model also includes terms for age, sex and cognition (Table 3).
Subjective (‘Difficulty hearing’): Logistic modelling of question association yielding odds ratios (OR) between no exposure and number of years indicated. Other details as for objective test. Similar results were obtained for ‘Difficulty hearing in noise’ (Table S1 in Results S1).
