International basic standard
The standard IEC 60118-0 entitled "Electroacoustics – Hearing aids – Part 0: Measurement of the performance characteristics of hearing aids" is the underlying standard for technical characterization and testing of hearing aids. For a potential worldwide usability, test reports for this standard are created exclusively in English and receive the ILAC signet besides the DAkkS and the ZLG signets.
Testing according to chapter 7
Scope of testing
Regular testing comprises all measurements from chapter 7 of IEC 60118-0:
- OSPL90-response curve
- Full on gain amplification response curve
- Normal acoustic response curve
- Total harmonic distortion
- Equivalent input noise
- Battery current
- Measurements in hearing aids with telecoil
Contact us in case you require optional test procedures according to chapter 9 of IEC 60118-0.
Combination with type testing
Within type testing of hearing aids, test procedures according to IEC 60118-0 are conducted. Therefore, it is possible to request testing according to IEC 60118-0 not only separately, but in combination with type testing. This is only a limited overhead, such that the combination saves effort, time and money.
