hl
- noun
- Specialized
- 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
-

-
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.

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'.
