Lep d value shown is calculated from the current LAeg and the current elapsed time Where the run time is short or the LAeg value is low the calculated Lep d value will also be low This is not unusual and is the correct calculation of the Lep d Lep d is defined by the UK Noise at Work Regulations as the total personal noise exposure to noise at work this figure is normalised to an 8 hour day taking into account of the average levels of noise in working areas and the time spent in them but taking no account of any ear protectors earmuffs or earplugs worn Basically Lep d is a measured Leq value expressed as an 8 hour The formula to calculate Lep d is LEP d LEX 8h L T at t 1010g Ae Where T is the duration of the person s working day in seconds T e 23 29 is 28 800 seconds 8 hours L 0 is the equivalent continuous A weighted sound pressure level as defined in ISO 1999 1990 Clause 3 5 in decibels that represents the sound that the person is exposed to during the working day Aeg Te Important facts to remember about Lep d 1 Lep d is not a measured value It is calculated from the Exposure Time and from the measured Leg value 2 Lep d is normalised to an 8 hour day This means that a measurement for a worker exposed to noise for 8 hours can be compared to the exposure of a person who works for 12 hours Lep d is always normalised to 8 hours 3 Lep d may be written as LEX 8h This is the same pa
