3.14.1 In addition to the spaces referred to in
                           sections 3.10 to 3.13, measurements shall be taken in all locations
                           with unusually high noise levels where seafarers may be exposed, even
                           for relatively short periods, and at intermittently used machinery
                           locations.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           3.14.2 In order to restrict the number of measurements
                           and recordings, noise levels need not be measured for normally unoccupied
                           spaces, holds, deck areas and other spaces which are remote from sources
                           of noise.
                        
                        
                        
                      
                     
                     
                     
                        
                        
                         
                           3.14.3 In cargo holds, at least three microphone
                           positions in parts of holds where personnel are likely to carry out
                           work shall be used.
