Common use of Noise Parameters Clause in Contracts

Noise Parameters. 4.2.1.1 The construction noise level should be measured in terms of the 30-minute A-weighted equivalent continuous sound pressure level (Leq). Leq (30 min) should be used as the monitoring parameter for the time period between 0700 and 1900 hours on normal weekdays.

Noise Parameters. 4.2.1.1 The construction noise level should shall be measured in terms of the 30-minute A-weighted equivalent continuous sound pressure level (Leq). Leq (30 Leq(30 min) should shall be used as the monitoring parameter for the time period between 0700 and 0700-1900 hours on normal weekdays. For all other time periods, Leq(5 min) shall be employed for comparison with the NCO criteria. As supplementary information for data auditing, statistical results such as L10 and L90 shall also be obtained for reference. A sample data record sheet is shown in Appendix C for reference.
