Cóip statach de shonraí a easpórtáiltear ó IATE ó am go chéile atá sa chnuasach seo. Níor cheart glacadh leis gurb ionann i gcónaí an t-eolas a thugtar faoi iontráil anseo agus a bhfuil sa leagan reatha den iontráil ar IATE. Is féidir an leagan reatha sin a cheadú ach cliceáil ar an nasc atá ar thaobh na láimhe deise ag barr gach iontrála. Breis eolais »

    Sainmhíniú "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." Tagairt "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)"
    Nóta 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.

    Nóta 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.

    Sainmhíniú 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 Tagairt "COM-EN, based on:Wikipedia > A-weighting. http://en.wikipedia.org/wiki/A-weighting [23.5.2013]"
    Nóta 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.
