Industrial Noise and Vibration Control The   main   purpose   of   industrial   noise   control   is   to   protect   the   hearing   of   the   people working in the production units, factories and workshops etc. Noise   generated   by   fluctuating   forces   in   structures...The   internal   forces   in   a   machine   are transferred   as   structure-borne   sound   to   the   surface   where   it   is   radiated   as   sound...The forces   can   be   either   steady,   caused   by   reciprocating   motion   in   an   engine,   or   transient caused   by   impacts.   ..More   noise   is   produced   if   a   task   is   carried   out   with   great   force   for   a short   time   than   with   less   force   for   a   longer   time...Since   the   structural   vibration   will   have to    radiate    as    sound    from    the    machine    surfaces    reduction    of    the    surface    area    or reduction    of    the    radiation    efficiency    of    he    surface    can    be    good    noise    control techniques...An   object   with   a   small   surface   area   may   vibrate   intensely   without   a   great deal   of   noise   radiation.   The   higher   the   frequencies,   the   smaller   the   surface   must   be   to prevent disturbance.
