    A-weighted equivalent continuous sound pressure level | LAeq | Leq | LpAeq
    en
    Definition LAeq refers to the "equivalent" average sound level measured using the A-weighting which is most sensitive to speech-intelligibility frequencies of the human ear. Reference ETV Cookbook http://etvcookbook.org/glossary/#L (21/5/07) and http://www.rushmoor.gov.uk/media/adobepdf/p/c/BrianRichardWoodProofofEvidence_1.pdf (16/5/07)
    Comment The LAeq parameter has become the norm at all planning inquiries and is the standard method ofundertaking noise assessment at large airports. It is an internationally-recognised unit.

    Comment Exprimé en Leq pondéré A, soit L(Aeq, t).Ce niveau acoustique continu équivalent est de plus en plus largement accepté comme unité de mesure de l’exposition prolongée au bruit. C’est l’unité retenue dans la plupart des textes des Etats membres de la Communauté européenne et des réglementations internationales.

    Definition factor applied to instrument-measured sound levels in an effort to account for the relative loudness perceived by the human ear, which is less sensitive to low audio frequencies Reference COM-EN, based on:Wikipedia > A-weighting. http://en.wikipedia.org/wiki/A-weighting [23.5.2013]
    Comment It is employed by arithmetically adding a table of values, listed by octave or third-octave bands, to the measured sound pressure levels in dB. The resulting octave band measurements are usually added (logarithmic method) to provide a single A-weighted value describing the sound; the units are written as dB(A). Other weighting sets of values - B, C, D and now Z - are discussed below.

    Definition sound pressure level1 of a signal which has been passed through a weighting filter reducing the effects of the low and high frequencies with respect to the medium frequencies, so as to reflect the acuity of the human ear, which does not respond equally to all frequencies1 sound pressure level: [ IATE:1366390 ] Reference COM-Term.

    Comment A-weighted sound pressure level is expressed in decibels (dB), but is often noted dB(A) or dBA to distinguish it from other weightings (e. g. B-, C- or Z-weighting)See also A-weighting: [ IATE:3550162 ]
