(c) An employee is exposed to the following levels of noise during his working day:
Note: The values of P,Q,R, and S, depend on the respective, 3rd ,4th ,5th , and 6th digit of your matric number as in the following number format: AD×xPQRS. For example, if your matric number is AD170154, it gives the value P=0,Q=1,R= 5 , and S=4, thus the duration of sawing activity is 0 hours with SPL is 90 dB( A), grinding activity is 1 hours with 91 dB( A), drilling activity is 14 minutes with 95 dB(A), and turning activity is 4 hours with 94 dB( A).
