ActiveElectroacoustics - Hearing aids - Part 4: Induction loop systems for hearing aid purposes - Magnetic field strength
电声学 助听器 第4部分：助听器用感应回路系统磁场强度
Application Summary AI generated
This standard specifies the measurement methods and performance requirements for the magnetic field strength generated by induction loop systems used with hearing aids. It is applied in the design, testing, and certification of audio frequency induction loop systems installed in venues like theaters, conference rooms, and public service counters to ensure compatibility with hearing aid telecoils. The standard also provides guidelines for evaluating the uniformity and coverage of the magnetic field to guarantee consistent audio signal reception for hearing aid users.
