Excessive noise levels are generally acknowledged to have adverse
effects on our environment. Studies indicate that excessive noise
levels can cause fatigue in exposed individuals, lower efficiency
and productivity, impaired speech communication, and hearing loss.
Excessive noise is almost everywhere today - in the office, in
schools, hospitals and other institutional facilities, in all
classes of public buildings, and in our factories. INDUSTRIAL NOISE
High noise levels in factories can make speech communication in the
plant difficult and at times impossible. Foremen are often unable
to hear warning shouts from co-workers. The problem of hearing loss
due to excessive noise exposure is of particular concern to
industry, and to the federal government. In the early 1970s, the
United States Congress passed the Occupational Safety and Health
Act (OSHA) which sets criteria for health hazards and established
limits for noise exposure of industrial workers. The OSHA Noise
Standard was amended in 1982 to require audiometric testing of all
employees exposed to noise levels of 85 dB or above for eight
hours. A NOISE IN COMMERCIAL AND INSTITUTIONAL BUILDINGS While
noise levels in offices, stores, schools, and other commercial and
institutional buildings seldom reach those encountered in many
industrial environments, they often reach levels which are
distracting to the occupants of such buildings. Impairment of
speech communica tion among workers, or inversely the lack of
speech privacy, are both deterrents to effiCiency and productivity
and are detrimental to the occupants' comfort and sense of
well-being."
