A worked dB EML example shows masking calculations in practice.

Evidence

We can calculate the dB EML of the following stimulus: a 1000-Hz wide noise, centered at 500 Hz, presented at a 40-dB LPC. Using Eq. 3–2 and Table 3–1, dB EML = 10log(50) + 40 − 11.5 = 45.5 dB EML. This masker has the ability to shift any threshold for a pure tone in quiet that is <45.5 dB HL to 45.5 dB HL. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 593
