Net weight means the weight of the goods themselves without packing materials and packing containers of any kind Minimum Weighted Average Coupon Test means a test that will be satisfied on any Measurement Date if the Weighted Average Coupon equals or exceeds 7.0%. For the purposes of this ordinance, the term is synonymous with the National Geodetic Vertical Datum (NGVD) of 1929, the North American Vertical Datum (NAVD) of 1988, or other datum, to which base flood elevations shown on a community's flood insurance rate map are referenced. It is used as a reference for establishing various elevations within the floodplain. Mean Sea Level means the average height of the sea for all stages of the tide. Weighted Average Pass-Through Rate For any Distribution Date, the weighted average of the Pass-Through Rates on the Mortgage Loans as of the second preceding Due Date (after giving effect to the payments due on the Mortgage Loans on that Due Date). See also " A-Weighted Decibel." Compatibility: The characteristics of different uses or activities that permit them to be located near each other in harmony and without conflict.Ī unit-less measure of sound on a logarithmic scale. A-Weighted Decibel (dBA).įor sound intensity level, this applies to the ratio of the sound intensity amplitude to the reference intensity amplitude of 1 pico-watt per square meter. and after addition of 10 decibels to sound levels in the night after 10 p.m. Table 3-4Population Density and Associated Ambient Noise Levels Notes: A-Weighted Decibel (dBA).Ĭommunity Noise Equivalent Level (CNEL): The average equivalent sound level during a 24-hour day, obtained after addition of five decibels to sound levels in the evening from 7 p.m. The reference pressure is 20 micro-pascals A-Weighted Decibel (dB(A)): An overall frequency-weighted sound level in decibels, which approximates the frequency response of the human ear. In the context of this Noise Element, the following terms are important to understand: A-Weighted Decibel (dBA): A decibel scale that approxi- mates the way the human ear responds to frequency lev- els. Day-Night Average Sound Level (DNL) 1.1.1 The Decibel (dB) All sounds come from a sound source-a musical instrument, a speaking voice, or an airplane passing overhead.Community Noise Equivalent Level (CNEL).
