Description
Return RMS amplitude ratio and decibel 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 RMS amplitude ratio and decibel difference.
When to use this tool
Use Acoustic Stimulus RMS Reference Gap when checking the stated hearing-test record, acoustic level, frequency or timing convention.
How to use the tool and how it works
- Enter rms, referenceRms. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read amplitudeRatio, decibelGap. Use the output convention below.
Return RMS amplitude ratio and decibel difference. Require positive rms/referenceRms; ratio = rms/reference, decibelGap = 20*(log10(rms)-log10(reference)).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| rms | Rms | Required. Finite number; strictly above 0. |
| referenceRms | Reference Rms | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| amplitudeRatio | Amplitude Ratio | Required. Finite number. |
| decibelGap | Amplitude-level difference using factor 20, not power-level factor 10. | Required. Finite number. |

}Limitations and assumptions
- The amplitude quantities must have compatible references and impedance assumptions; this does not establish safe sound exposure or clinical hearing levels.
- 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.
