Many machine tools today are isolated from the floor with special mounting devices to limit their vibration transmission. This is primarily done to prevent disturbance of other machines. Machines are also enclosed by rigid structures lined with acoustic material to deaden sound transmission. This is primarily done to protect the workers from hearing loss. This is no small concern. Shops with high noise background levels (e.g., stamping plants) must undertake steps to conserve the hearing of the workers. Measures include mandatory hearing protection usage, annual hearing examinations, and limited exposure to exceptionally high noise operations, such as some forging operations. Release of compressed air is of real concern, as it is one of the leading causes of high noise levels in many plants
While noise and vibration effects are primarily limited to the
confines of the plant, noise will travel outside of the plant and may have
an effect on wildlife, making an area less hospitable for animals. Vibrations
have an effect on machine tool and manufacturing processes, leading to
scrap and worn out machine tools entering the waste stream.
