Which statement about Leq, Lmax, and Lmin is NOT true?

Which statement about Leq, Lmax, and Lmin is NOT true?

• A. Leq is the equivalent continuous A-weighted sound level.
• B. Lmax is the maximum instantaneous level.
• C. Lmin is the minimum instantaneous level.
• D. Lmax is the Leq value.

Answer: (D)

Leq represents the energy-averaged sound level over the measurement period with A-weighting, capturing the overall exposure rather than any single moment. Lmax is the maximum instantaneous level observed, and Lmin is the minimum instantaneous level observed. The statement that Lmax is the Leq value is not true because Leq is a time-averaged energy measure, not the peak. The other statements are correct: Leq is indeed the equivalent continuous A-weighted level; Lmax corresponds to the highest instantaneous level; Lmin corresponds to the lowest instantaneous level.
