Table 1.

Noise levels indicators in phase 1 and phase 2 (dB(A))

Noise level (dB(A))	LAeq	Lmax	Lmin	L90	L50	L10
Phase 1	60.3	76.5	48.5	54.2	58.9	62.8
Phase 2	56.9	71.6	47.8	48.5	54.2	60.4

L₁₀: exceeded noise level for 10% of the measurement period (crest noise)

L₅₀: exceeded noise level for 50% of the measurement period (median noise)

L₉₀: exceeded noise level for 90% of the measurement period (background noise)

The L₁₀ and L₉₀ are extensively used for impulsive sound levels and Background Noise respectively

L_Aeq = Equivalent Sound Level. It quantifies the noise environment to a single value of sound level for any desired duration. This descriptor correlates well with the effects of noise on people

Lmax = Maximum Sound Level: a maximum level during the measurement period

Lmin = Minimum Sound Level during the measurement period
