Sažetak
This paper describes the implementation of composed audio test signal (CATS) based test system for evaluation of electroacoustic performance of hearing aids. The system applies a frequency-shaped CATS sequence to a hearing aid as an acoustic stimulus and measures the acoustic response of the aid in IEC standard occluded-ear stimulator. The frequency response can then be found by taking the discrete Fourier Transform of the impulse response. This method has several advantages over traditional noise-based methods regard measurements in the absence or presence of the external interference noise.
