SOURCES OF EXPOSURE TO INFRASONIC NOISE IN THE WORKING ENVIRONMENT
 
 
The main sources of infrasonic noise in the work environment are:
  • low-speed machines, including flow-through machines, such as motors, compressors, fans,
  • energy equipment - boilers, chimneys, coal mills, 
  • metallurgical furnaces, in particular arc furnaces,
  • some devices used in the foundry industry, e.g. moulding machines,
  • means of transport, e.g. lorries, buses, trains, planes,
  • wind turbines.
