Correlation matrix of hearing loss outcomes, including age-corrected standard threshold shift (STS) prevalence, non-age-corrected STS prevalence, age-corrected high frequency hearing loss rate (dB/year), hearing impairment prevalence, average noise exposure during hearing conservation program (HCP) assessment (dBA1), average 10-year noise TWA exposure for the facility (dBA), and 10-year average noise exposure change rate (dBA/year) for 14 metals manufacturing facilities in the US.
