- Revision: 1.0.0
For example: hearing aid or cochlear implant as type of device.
Include:
openEHR-EHR-CLUSTER.device.v1
- Left [The hearing device is worn at the left side.]
- Right [The hearing device is worn at the right side.]
For example: information about hearing device settings.
For example: medication or noise exposure prior to test.
Provide further specification of 'Type of test stimulus', if a frequency is required. For example: frequency of pure tone or center frequency of narrowband noise.
Property: Frequency
Units:
- 20.0..20000.0 Hz
Limit decimal places: 0 - 0.125..16.0 kHz
Limit decimal places: 3
- Right ear [The test stimuli were presented to the right ear.]
- Left ear [The test stimuli were presented to the left ear.]
- Binaural [The test stimuli were presented to both ears simultaneously.]
Property: Loudness
Units: -50.0..200.0 dB HL
Limit decimal places: 2
Property: null
Units: 0.0..1000.0 CU
Limit decimal places: 1
It can either be described through sampled data points from the curve (pairs of response category and stimulus level), or the curve equation and corresponding fit parameters (slope values and specific curve samples).
A literature reference could be included if applicable. For example: "BX" from Oetting et al. 2014 or exponential fit.
These data points can be used to describe the curve through sampled data points or as fit parameters included in the curve equation. For example: response category of 2.5 CU, 25 CU and 50 CU.
For example: 2.5 CU, 25 CU, 50 CU.
Property: null
Units: 0.0..1000.0 CU
Limit decimal places: 2
Property: Loudness
Units: -50.0..200.0 dB HL
Limit decimal places: 0
Include reference in 'Type of fit' if applicable.
Use this parameter, if only one slope value is required. For example: in case of a linear curve.
Property: null
Units: 0.0..100.0 [arb'U]{CU}/dB[SPL]{HL}
Limit decimal places: 0
Property: null
Units: 0.0..100.0 [arb'U]{CU}/dB[SPL]{HL}
Limit decimal places: 0
For example: other parameters used to describe the loudness curve.
For example: if measurement was not completed or maximum level was reached.
openEHR-EHR-CLUSTER.exclusion_
The scaling method includes details on the experimental procedure. For example: verbal descriptions of response categories.

Choice of:
- Coded Text
- Loudspeaker [The stimulus is presented via a loudspeaker.]
- Insert earphone [The stimulus is presented via insert earphones.]
- Headphone [The stimulus is presented via external headphones - either circumaural or supraaural.]
- Direct streaming to sound processor [The stimulus is directly streamed to the sound processor of a hearing device.]
- Text
For example: type of headphone or speaker.
Include:
openEHR-EHR-CLUSTER.device.v1
If the type of stimulus is broadband, use 'Name of test stimulus' for further specification. If the type of noise is a tone or a narrowband noise, use 'Frequency of test stimulus' for further specification.
Choice of:
- Coded Text
- Tone burst [The test stimulus is a tone burst.]
- Click [The test stimulus is a click.]
- Warble tone [The test stimulus is a frequency modulated tone.]
- Pure tone [The test stimulus is a pure tone.]
- Narrowband noise [The test stimulus is a narrow band noise centred on the specified frequency.]
- Pulsed pure tone [The test stimulus is a pulsed pure tone.]
- Broadband noise [The test stimulus is a broad band noise.]
- Natural sound [The test stimulus is a natural/recorded sound.]
- Low-noise narrowband noise [The test stimulus is a low-noise narrowband noise centred on the specified frequency.]
- Text
Provides name of test stimulus, if it has an established name or description of natural sound. For example: IFNoise, Icra1 or, for natural sounds, birds.
This data element is commonly used in industry hearing programs.
