Jak vypadá vzorec platný pro hladinu intenzity zvuku L?
Správná odpověď je: A
Hladina intenzity zvuku L představuje matematicky upravené znázornění podílu intenzity daného zvuku I a intenzity zvuku I0, která odpovídá prahu slyšení, vzorec má tedy tvar L = 10 · log (I/I0).
V praxi lze určovat hladinu řady dalších akustických veličin, např. hladinu akustického výkonu nebo hladinu akustického tlaku. Druhou zmíněnou veličinu lze vypočítat podle vzorce L = 20 · log (p/p0).
