Electroacoustics. Hearing aids - Methods for characterising signal processing in hearing aids with a speech-like signal Ingestion-build-68772 ― How to ensure interoperability1 Scope This part of IEC 60118 specifies a test signal designed to represent normal speech, the International Speech Test Signal (ISTS), together with the procedures and the requirements for measuring the characteristics of signal processing in air conduction hearing aids. The measurements are used to derive the estimated insertion gain (EIG). For the purposes of characterizing a hearing aid for production, supply and delivery, the procedures and
