How to Use This Calculator
  1. Obtain your audiogram results from a licensed audiologist.
  2. Enter the hearing threshold values (in dB HL) at 500 Hz, 1 kHz, 2 kHz, and 4 kHz.
  3. The calculator averages the four frequencies to produce your Pure-Tone Average (PTA).
  4. Review the severity category (e.g., mild, moderate, severe) shown in the output.
  5. Share the PTA result with your audiologist when discussing hearing aid candidacy.

How the result changes with dB @ 2 kHz

What each input means

dB @ 500 Hz
Air conduction hearing threshold at 500 Hz from your audiogram.
dB @ 1 kHz
Air conduction hearing threshold at 1000 Hz from your audiogram.
dB @ 2 kHz
Air conduction hearing threshold at 2000 Hz from your audiogram.

What each result means

PTA (0.5-2k)
Pure-tone average across 500, 1000, and 2000 Hz -- the speech frequency range.
Severity (WHO-style)
Hearing loss classification based on WHO severity grades.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    dB @ 500 Hz = 25, dB @ 1 kHz = 35, dB @ 2 kHz = 45 = 3 input(s) provided
  2. Calculate PTA
    PTA = pta
    35 = 35
  3. Calculate Severity
    Mild = Mild
