Descriptive statistics of the SPL_zp, SPL_rms and SEL_ws of the ambient noise.

Parameters are given as the mean ±SD, with ranges denoting minimum and maximum values. SELss was identical to SPLrms, Means with different lowercase superscripts refer to post hoc Duncan's multiple-comparison tests that yielded significant results (p<0.05) for OCTA-KONG pile driving. Subscript 'a' denotes sound recorded by the BS recording system, 'b' denotes sound recorded by the SM2M recording system and 'c' denotes the combined results of the BS and SM2M recording systems.
