A-weighting is associated with which statement about noise measurement?

Explanation:
A-weighting mirrors how the human ear perceives loudness across frequencies, so measurements in dB(A) are used to estimate potential health hazards from noise, especially hearing damage, in real-world exposure scenarios. It is not flat across frequencies, and it does not emphasize low frequencies—A-weighting attenuates very low and very high frequencies and emphasizes the mid-range where our ears are most sensitive. It’s also used for general noise exposure assessments, not solely for impulse noise.
