Noise Monitoring and Assessment Results
[WEEK 5]
9th December 2016 - 7.30 am

We had collected the result of our noise monitoring for this week. The results shows the noise level at each second for an hour [60sec x 60min]. So, we had a total of 3600 data. To simplify the data obtained, we had calibrated a line graph to observe the pattern.
The highest level recorded by the equipment is data on 2463 seconds which is at 8:11:56 AM where the level reaches up to 81.8 dB. From our observation, the increase on the level of noise at that particular time is due to a disturbance that occur.
L10
L10 is the noise level exceeded for 10 percent of the time of the measurement period. For week 5, the noise limit of L10 was 64.6 dBA means that over a period of one hour. The noise from morning market activities can only exceed 64.6 dBA for a total of six minutes.
Leq
Leq is the time-averaged level and is equivalent to the average energy over the whole measurement period. Leq, or LAeq as it is know called, has become the preferred international descriptor for environmental sound and will be incorporated into all new Standards. For week 5, the Leq is still 70dB.
L95
L95 is the level exceeded for 95 percent of the time and represents the background level without any morning market noise present. The morning market background noise level in week 5 [59.8] is slightly higher from week 4.
Max dB
Max dB is the maximum level measured over a period of one hour, but it is not the same as, or not as high as, an individual peak level. In week 5, the max dB is 86.6 dB.
Difference between L10 and Leq
In week 5, the L10 is around 5 to 6 decibels lower than the Leq.
SEL
Sound Exposure Level (SEL) is numerically equivalent to the total Sound Energy.
SEL = Leq + 10 log10 T
SEL = 70 + 10 log 10 3600
SEL = 105.5 dB
