87A.05 NOISE STANDARDS.
Allowable noise levels for the operation of a shooting range are the levels determined by
replacing the steady state noise L10 and L50 state standards for each period of time within each
noise area's classification with a single Leq(h) standard for impulsive noise that is two dBA lower
than that of the L10 level for steady state noise. The noise level shall be measured outside of
the range property at the location of the receiver's activity according to Minnesota Rules, parts
7030.0010 to
7030.0080, as in effect on May 28, 2005. For purposes of this section, "Leq(h)"
means the energy level that is equivalent to a steady state level that contains the same amount of
sound energy as the time varying sound level for a 60-minute time period.
