Mean Output Level metric quantifies bass efficiency across seats
Evidence
Figure 14.23 answers the second important question: now that one can identify listener and loudspeaker arrangements that yield superior seat-to-seat consistency, which listener and loudspeaker arrangement(s) generate the highest sound levels from a given set of subwoofers? The MOL metric gives a relative low-frequency efficiency for each configuration (averaged SPL over all seats from 20 to 40 Hz, normalized to account for the number of subwoofers used). — Toole, Floyd E, Sound reproduction- the acoustics and…, 1597
