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 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.
