Description
Return a measured-to-labeled frequency gap.
Audiological records depend on ear/channel identity, stimulus calibration, timing and decibel reference conventions. A local level difference or response share can reconcile supplied observations while hearing ability, safe sound output and clinical test interpretation require validated procedures and professional assessment.
Return a measured-to-labeled frequency gap.
When to use this tool
Use Audiogram Frequency Axis Label Gap when checking the stated hearing-test record, acoustic level, frequency or timing convention.
How to use the tool and how it works
- Enter measuredHz, labeledHz. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read octaveGap, frequencyRatio. Use the output convention below.
Return a measured-to-labeled frequency gap. Require positive measuredHz/labeledHz; frequencyRatio = measured/labeled, octaveGap = log2(ratio).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| measuredHz | Measured Hz | Required. Finite number; strictly above 0. |
| labeledHz | Labeled Hz | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| octaveGap | Octave Gap | Required. Finite number. |
| frequencyRatio | Frequency Ratio Unit: 1. | Required. Finite number. |

}Limitations and assumptions
- No actual frequency measurement, instrument calibration or hearing diagnosis is performed.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use calibrated equipment and a complete validated audiological method; consult an appropriate hearing-health professional for diagnosis, fitting or safe exposure decisions.
