Consider the case where a noise level of 90 dBA exists for five minutes and is followed by a reduced noise level of 60 dBA for 50 minutes and an increase to 70 BA for 10 minutes. What is the equivalent continuous energy level for the whole period in BA? Assume a 5-minute sampling interval. 0 83.00 O 78.99 O 74.25 O 70.00 Consider the case where a noise level of 90 dBA exists for five minutes and is followed by a reduced noise level of 60 dBA for 50 minutes and an increase to 70 BA for 10 minutes.
