Application: Health
BS EN IEC 60118-16:2022 - Start year: : 2022
 Description:

Electroacoustics. Hearing aids Definition and verification of hearing aid features

Notes:

This standard BS EN IEC 60118-16:2022 Electroacoustics. Hearing aids is classified in these ICS categories:

  • 17.140.50 Electroacoustics
  • 17.140.01 Acoustic measurements and noise abatement in general
  • 11.020.10 Health care services in general
  • 11.180.15 Aids for deaf and hearing impaired people

This part of IEC 60118 gives definitions for common hearing aid features such as noise reduction or feedback reduction, etc. Only acoustical inputs are considered. Binaural features are currently not covered in this document. In addition, measurement procedures are described to verify hearing aid features. The objective is not to evaluate the performance of features but to verify their existence and functionality. Furthermore, definitions and procedures are kept as general as possible so that this document can be applied to various types of hearing aids, e.g. air conduction hearing aids or bone conduction hearing aids. To this end, the general definition for hearing aid of IEC 60118-0:2015 is adopted, and this document does not refer to any specific ear simulator or acoustic coupler but uses a general definition of a coupler. However, if a general view is not applicable or leads to unclear or complex wording, the situation for an air conduction hearing aid is considered, only. Nevertheless, in Clause 4, an explanation is given on how this document can be applied to hearing aids which do not use air conduction.

CSN EN 50530 - Start year: : 2010
 Description:

This European Standard provides a procedure for the measurement of the efficiency of the maximum power point tracking (MPPT) of inverters, which are used in grid-connected photovoltaic systems. In that case the inverter energizes a low voltage grid with rated AC voltage and rated frequency. Both the static and dynamic MPPT efficiency is considered. Based on the static MPPT efficiency and conversion efficiency the overall inverter efficiency is calculated. The dynamic MPPT efficiency is indicated separately.
