||The introduction to this booklet reviews briefly the nature, physics and production of ultrasound, which is employed in medicine, non-destructive testing, cleaning, welding, machining, etc. Long-term exposure to noise levels exceeding 85dB(A) can cause irreversible deafness due to effects on the middle ear. Review of results of studies on physiological effects and hearing damage, and of ultrasound measurement techniques. Occupational health measures are based on the establishment of TLVs for intensity and noise level, and on rules for personal protection. Example of noise emitted by certain installations and description of health engineering techniques for noise control at the source and in the vicinity of the source (design, enclosure, coverings for vats, workplace design and layout).
