A-WEIGHTED SOUND LEVEL - dB(A): a measurement of sound pressure level, which
      has been filtered or weighted to progressively de-emphasize the importance of frequency
      components below 1,000 Hz and above 5,000 Hz. This range corresponds to the human
      speech band and reflects that human hearing is more sensitive to the mid-range frequencies
      within this range than the frequencies below and above this range.
