Description
Return a signed tympanometry reference difference.
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 signed tympanometry reference difference.
When to use this tool
Use Tympanometry Reference Pressure Sign when checking the stated hearing-test record, acoustic level, frequency or timing convention.
How to use the tool and how it works
- Enter observed, reference, reverseAxis. 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 a signed tympanometry reference difference. signedGap = observed-reference, reversed when reverseAxis.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| observed | Observed | Required. Finite number. |
| reference | Reference | Required. Finite number. |
| reverseAxis | Reverse Axis | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedGap | Signed Gap | Required. Finite number. |

}Limitations and assumptions
- Both values need compatible pressure units and origin; no tympanogram, hearing diagnosis or clinical reference is interpreted.
- 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.
