  • Normal hearing was documented by pure-tone hearing screening bilaterally (20 dB HL) at 500, 1000, 2000, and 4000 Hz (American Speech-Language-Hearing Association, 1997).

Examples

  • The tank can hold a volume of 1 hl, which is equivalent to 100 liters of water.

  • All listeners had bilaterally normal hearing, defined as pure-tone thresholds of 20 dB HL or better at octave frequencies between 0.25 kHz and 8 kHz.

  • Hearing assistive technology is reported to be advantageous to individuals with HL in order to improve the SNR across a variety of environments.

    Academic text (2013)
  • All of the children had a corrected pure-tone average < 45 dB HL.

    Academic text (2013)
  • Speech recognition testing was conducted in the sound field with a 50 dB HL presentation level at 3 months and 60 dB HL at 6 months.

    Academic text (2005)
  • The passages were presented at 45 dB HL, with an SNR determined by the adaptive procedure.

  • AC HTL = air conduction hearing threshold level. dB = decibel, HL = hearing level.

    Academic text (1996)
  • All listeners passed a hearing screening at 20 dB HL for the frequencies 0.5, 1, 2, and 4 kHz (American Speech-Language-Hearing Association, 1997).

    Academic text (2013)
  • For the nontest ear, thresholds of 30 dB HL at all frequencies were permitted with an allowance for a one-frequency dip up to 40 dB HL.

    Academic text (2012)
  • All listeners had pure-tone thresholds no greater than 20 dB HL at octave frequencies 250-8000 Hz (American National Standards Institute, 2010; Table 1).

Etymology

The word hl stands for hecto + liter, where hecto means 'hundred' and you see it in hectare. So hl is simply a unit of 'one hundred liters'.
