Important! Please note that the hearing instrument fitting standard effectively became outdated with the use of Noah 3 and 4 API’s. Prior to NOAH 3 a Noah 2 fitting module would find it important to reference the date of the audiogram that was used for the fitting. This date was stored via the hearing instrument fitting data standard. The date of audiogram date element is the only field in the standard.
With Noah 3 and 4 modules can now create a reference to the specific audiogram action.
