Rezumat : este masura eficientei unui difuzor. Deobicei il vei vedea in dB @ W/m sau, tradus, inseamna cati dB auzi daca difuzorului respectiv ii furnizezi un watt si stai la un metru departare de el. Cu cat mai mare, cu atat mai bine.

 

Edit : la inceput intrebasei si ce este, de unde explicatia. Din cate stiu, valorile se invart in jurul a 121, desi nu pot garanta. Pentru ce intrebi?
