l&#8217;\u00e9nergie sonore, notamment en la convertissant parfois en chaleur. Le mot \u00ab\u00a0absorption\u00a0\u00bb est \u00e9quivalent \u00e0 \u00ab\u00a0avaler\u00a0\u00bb et \u00ab\u00a0aspirer\u00a0\u00bb. Le terme est utilis\u00e9 de mani\u00e8re tr\u00e8s similaire \u00e0 la dissipation et \u00e0 l&#8217;absorption du son. La distinction avec la dissipation est qu&#8217;elle se r\u00e9f\u00e8re exclusivement \u00e0 la conversion en \u00e9nergie autre que le son, en particulier la chaleur, alors que l&#8217;absorption peut en principe se r\u00e9f\u00e9rer \u00e9galement \u00e0 d&#8217;autres types de &#8220;disparition&#8221; du son (voir coefficient d&#8217;absorption). L&#8217;att\u00e9nuation du son, en revanche, d\u00e9signe tout type de r\u00e9duction de l&#8217;intensit\u00e9 sonore qui n&#8217;est pas n\u00e9cessairement li\u00e9e \u00e0 une r\u00e9duction de l&#8217;\u00e9nergie sonore, par exemple par divergence, c&#8217;est-\u00e0-dire en r\u00e9partissant l&#8217;\u00e9nergie sonore sur une plus grande surface.<\/p><p>Deux variables sont utilis\u00e9es pour d\u00e9terminer quantitativement l&#8217;absorption acoustique, le coefficient d&#8217;absorption et le degr\u00e9 d&#8217;absorption.<\/p><p>Comme en optique, le coefficient d&#8217;absorption est le coefficient exponentiel de la diminution de l&#8217;intensit\u00e9 d&#8217;une onde plane (c&#8217;est-\u00e0-dire sans divergence). Il s&#8217;agit d&#8217;une constante mat\u00e9rielle du support de transmission pendant la propagation du son. Comme cette constante mat\u00e9rielle se caract\u00e9rise uniquement par une absorption dissipatrice, elle est pratiquement identique au coefficient de dissipation.<\/p><p>Le degr\u00e9 d&#8217;absorption acoustique est une mesure de l&#8217;intensit\u00e9 sonore dissip\u00e9e. La r\u00e9flectance sonore est une mesure de l&#8217;intensit\u00e9 du son r\u00e9fl\u00e9chi. Le coefficient de transmission du son est une mesure de l&#8217;intensit\u00e9 du son transmis.
