The Basics
Social and psychological consequences of hearing loss - ANS-Social withdraws,
frustration, anger, difficulties with personal relationships
STS - ANS-Significant Threshold Shift
CAOHC - ANS-Council for Accreditation in Occupational Hearing Conservation
PTS - ANS-Permanent Threshold Shift
TTS - ANS-Temporary Threshold Shift
How many workers are exposed to hazardous noise at work - ANS-22 million
Manufacturing accounts for what % of NIHL - ANS-80%
NIHL - ANS-noise-induced hearing loss
What job has highest prevalence of noise exposures - ANS-mining
Occupational noise sources examples - ANS-industrial machinery, construction
equipment, explosives, farm equipment, musical instruments
non-occupational noise sources - ANS-motorcycles, firearms, carpentry equipment,
lawn tools, personal listening devices
Non-auditory effects of noise - ANS-negative effects on job performance, stress leading
to hypertension and ulcers
NIHL disability economic impact - ANS-$240 million per year
Sound has 3 main characteristics - ANS-Frequency(related to pitch), time refers to the
duration of the sound energy, intensity/amplitude(related to loudness)
