referent for CAOHC - ANS-Council for Accreditation in Occupational Hearing Conservation
Key info about CAOHC - ANS-published hearing conservation manual used to train techs in
programs, offers certification to audiologists, offers training for occupational hearing
conservationists
COUNCIL
referent for NHCA - ANS-National Hearing Conservation Association
key information about NHCA - ANS-national membership organization open to audiologists and
other professionals interested in hearing conservation, publish brochures, host national
conference, offer CEUs, published guideline on BASELINE REVISION
key roles CAOHC - ANS-train and certify techs as OHCs, train and certify course directors, and
professional supervisors, monitor/comment on pending hearing conservation legislation,
produce publications
summarize NHCA - ANS-membership organization, includes many different professions
(audiologists, engineers, industrial hygienists, safety pros, physicians, nurses), has liaisons and
reps in ANSI, AAA, OSHA
rationale for hearing conservation - ANS-NIHL is preventable, hearing loss is permanent,
hearing quiet is a QOL issue, preserving hearing optimizes communication abilities, improves
job performance, decreases fatigue/absenteeism
occupations at risk for hazardous noise exposure - ANS-manufacturing, construction, forestry
and fishing, transportation and agriculture, military, mining
auditory effects of noise - ANS-SNHL (MHL or CHL if trauma), tinnitus, hyperacusis, distortion
(pure-tones not perceived as pure), diplacusis (a tone of one frequency and the pitch is
perceived as different in each ear)
non-auditory effects of noise - ANS-lost productivity, increased likelihood of on-the-job injuries,
increased blood pressure, fatigue, irritability, absenteeism/poor attitude, communication difficulty
hazardous noise sources and levels - ANS-manufacturing processes, power tools, machinery,
transportation, weapons/guns, music
85 dBA+
, effect of NIHL on communication - ANS-hard for HF HL, hard with background noise, critical for
safety,
chemicals that increase NIHL when combined with hazardous noise - ANS-xylene, toluene,
methyl-ethyl ketone, styrene, toluene
impulsive noise - ANS-sharp rise & rapid decay in sound level, lasts <1 second, caused by force
over time
impact noise - ANS-single collision of one mass in motion with a second mass (at rest or in
motion)
intermittent noise - ANS-levels are interrupted by intervals of relatively low sound levels
factors that increase NIHL risk - ANS-age, smoking, chemical exposure, opiods
osha 83 - ANS-hearing conservation amendment; describes how to deliver a hearing
conservation program and damaging noise levels and durations
NIOSH 1998 - ANS-damage risk criteria; describes damaging noise levels & durations that differ
from OSHA 1983
AAA guideline says what is best practice - ANS-NIOSH
describe need for hearing conservation - ANS-noise is 2nd most common cause of acquired
hearing loss, NIHL is a commonly reported occupational injury, noise exposure is associated
with adverse health effects, prevalence of hearing loss in adolescents has increased
describe audiologists role in hearing conservation - ANS-advise company managers (different
testing approaches, types of audiometers, record maintenance and retention), select, maintain,
and calibrate equipment, select testing areas & document low ambient noise, train retrain and
supervise technicians, monitor and retest workers with problem audiograms, review and
interpret tests including tests by technicians, help determine work-relatedness of HL to refer to
ENT, provide written feedback and rx to workers, identify and implement criteria for retesting, id
problem audios, refer for ENT, revise baselines as needed
describe potential collaborators in hearing conservation - ANS-ENTs, physicians, auds,
occupational health nurses, safety personnel, HR managers, IT managers, company leaders,
acoustical, industrial, safety engineers
list 7 parts of hearing conservation program - ANS-noise measures, noise controls, monitor
hearing, HPDs, train and motivate, keep records, evaluate effectiveness
