b.A hearing conservation program including audiometric (hearing) testing
c.A program only if exposure reaches 120 dBA
d.A one-time hearing test at hire and never again
Giải thích
When the 8-hour average noise exposure reaches or exceeds 85 dBA, the employer must establish a hearing conservation program that includes noise monitoring, audiometric testing, training, and hearing protection. At 88 dBA the program is required. Option a stops at protectors and omits monitoring and testing. Option c sets the threshold far too high. Option d omits ongoing audiometric testing that detects hearing loss early.
