Description
Compare supplied measured and target tone levels.
Hearing records depend on frequency, laterality, masking status, calibration and level reference. A no-response label differs from a measured threshold, while an air-minus-bone gap requires comparable test conditions. Device charge arithmetic and scalar signal offsets do not establish hearing status or suitable care.
Compare supplied measured and target tone levels.
When to use this tool
Use Test Tone Level Calibration Residual when you already have targetLevel, measuredLevel and need to compare supplied measured and target tone levels.
How to use the tool and how it works
- Enter targetLevel, measuredLevel. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedGap. Use the output convention below.
Return measuredLevel-targetLevel with signs preserved.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| targetLevel | Target Level | Required. Finite number. |
| measuredLevel | Measured Level | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedGap | Signed Gap | Required. Finite number. |

}Limitations and assumptions
- The level unit and reference must match. No calibration curve, device output, acceptable tolerance, hearing status or safe exposure is verified.
- 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
Review original audiograms, instrument settings, test records and the complete clinical context. Use an appropriate professional assessment for interpretation; local unit conversions and supplied labels do not choose tests, presentation levels or intervention.
