BS EN 60118-2:1996 is a European Standard titled "Hearing aids - Part 2: Specification of hearing aid characteristics". This standard specifies the performance characteristics of hearing aids, including their frequency response, output sound pressure level, and battery drain.
The standard covers a range of hearing aid types, including behind-the-ear (BTE), in-the-ear (ITE), and canal hearing aids. It provides detailed specifications for each type of hearing aid, including their maximum gain, frequency range, and input/output characteristics.
BS EN 60118-2:1996 also specifies the requirements for hearing aid testing, including tests for frequency response, maximum output, and battery drain. It provides guidelines for the interpretation of test results and the comparison of different hearing aid types based on their performance characteristics.
Compliance with BS EN 60118-2:1996 is required in many countries to ensure the safety and quality of hearing aids used in a wide range of applications. The standard has been updated several times since its initial publication to reflect the latest developments in hearing aid technology and testing methods.
