1. Check for availability. And the setting of the * Threshold Level 80 dBA noise level at the gauge starts to calculate the cumulative noise at 90 dBA * Criteria Level * The rate at which energy is doubled (Energy Exchange Rate).
1. Check for available and configurations: * Threshold Level that 80 dBA volume as sound level meter used to calculate cumulative start *. Criteria Level that 90 dBA * the rate at which energy is doubled (Energy Exchange Rate) .
