Is DNL appropriate for airport noise zoning

Abstract: Acoustics 08 Paris 1967The use of the DNL metric in airport noise zoning is based in the works of Schultz, that were later improved by Fidell. The basic idea is to use the percentage of highly annoyed people as a parameter to organize the area around airports. In urban zoning it is recommended to use the equivalent sound level LAEQ, which uses different criteria to day and night periods to define the land use. With regards to airport noise one may use LAD and LAN metrics which are the equivalent sound levels d… Show more

“…-Outside the dwellings during the night, the LAeqN indicator varies between 62.4 and 60.5 dB (A). These values are > 40 dB (A) the strong sleep threshold disturbance (Slama et al, 2008). -The estimated L DN level is between 70.01 and 68.1 dB (A), also exceeding very clearly the level of 52.6 dB (A) level which corresponds to the upper limit for strictly urban residential zones in NBR 10151; -L DN levels are all above 65 dB (A), which tell us that the test building zones are sensitive zones to noise generated by Bamako airport air traffic (Slama et al, 2008).…”

“…Noise sensitive zones around airports are forbidden at noise levels above 65 dB (A), but in practice lower levels can also cause problems and it cannot be considered the only limit between residential and nonresidential zones (Slama et al, 2008).…”

“…At the airport zoning, areas sensitive to noise are prohibited to level noise exceeding 65dB(A), but in practice, lower levels can cause annoyance too, it can't be considered as the only boundary between residential and non-residential areas (Slama, 2008).…”
