PAPER HEARING CONSERVATION
COMPREHENSIVE QUESTIONS AND ANSWERS
GRADED A+
◉ American Board of Audiology (ABA). Answer: An autonomous
organization dedicated to enhancing audiologic services to the
public by promulgating universally recognized standards in
professional practice
◉ American College of Occupational and Environmental Medicine
(ACOEM). Answer: A national professional organization
representing physicians and other healthcare professionals
specializing in the field of occupational and environmental medicine
◉ American Conference of Governmental Industrial Hygienists
(ACGIH). Answer: Member-based organization that advances
occupational and environmental health
◉ American Industrial Hygiene Association (AIHA). Answer: A
national professional organization that administers comprehensive
education programs open to all practitioners in industrial hygiene,
occupational health, environmental health, and safety domestically
and abroad
,◉ American National Standards Institute (ANSI). Answer:
Organization that promotes and facilitates voluntary consensus
standards and conformity assessment systems to ensure the safety
and health of consumers and the protection of the environment
◉ American Society of Safety Engineers (ASSE). Answer: Is the
oldest and largest professional safety organization. ASSE members
manage, supervise and consult on safety, health, and environmental
issues in industry, insurance, government and education
◉ American Speech-Language-Hearing Association (ASHA). Answer:
A national professional, scientific, and credentialing association for
audiologists, speech-language pathologists, speech, language, and
hearing scientists, audiology and speech-language pathology
support personnel and students
◉ American Tinnitus Association (ATA). Answer: Organization
devoted to informational exchange and finding a cure for tinnitus
◉ Americans with Disabilities Act of 1990 (ADA). Answer: A wide-
ranging civil rights law that prohibits discrimination based on
disability
◉ amplification. Answer: An increase in sound level or loudness
,◉ amplitude. Answer: The psychological analog of the human ear's
perception of loudness. As sound pressure increases, the human ear
perceives an increase. Also called sound level, loudness, or intensity
◉ amplitude-dependent hearing protection devices. Answer:
Hearing protection that provides different levels of attenuation
depending on the sound level in the environment. Also called
nonlinear hearing protection devices
◉ anatomy. Answer: The study of the body and its parts
◉ annoyance (noise). Answer: Usually refers to community noise
problems such as airports or race car tracks. Can also be used to
describe the irritability from noise exposure
◉ antiviral, acoustically transparent barriers. Answer: Disposable
covers used to keep earphone cushions clean and sanitary
◉ area noise measurements. Answer: Sound level meter
measurements taken in industry to determine noise levels in an area
◉ asymmetric hearing loss. Answer: A hearing loss that is
significantly worse in one ear
, ◉ attenuation. Answer: Noise reduction. Objectively: decrease in
intensity. Subjectively: decrease in loudness
◉ audiogram. Answer: Graph displaying the audible threshold in
Hearing Level (HL) for standardized sound frequency measured
with an audiometer
◉ audiologist. Answer: Professional specializing in the prevention,
assessment, diagnosis, and rehabilitation of hearing and balance
impairments
◉ audiometer. Answer: Device or machine used to evaluate hearing
levels (i.e., hearing acuity)
◉ audiometer calibration system. Answer: Set of instruments that
can measure sound outputs from an audiometer and its earphones
and confirm that the acoustic output of the equipment meets
requirements of established calibration standards. Also called
acoustic calibration system
◉ audiometric calibration. Answer: Checks conducted to ensure
consistent and proper results are obtained from the audiometric
equipment. These checks include daily listening and biological
checks as well as annual exhaustive electro-acoustic calibration
