Induction loop measurements (Enabled when MiniLINK is installed) Hearing aids are using Induction Loop Systems (AFILS) to transmit speech- and audio-signals. NTi Audio has responded to the demand of the market for proper qualification and verification of induction loop systems installations. The AFILS mode is an extension of the standard firmware functionality and is available free of charge for all Minilyzer users with the MiniLINK USB interface installed. The Minilyzer supports all calibrated AFIL sensors and displays the actually measured field strength in A/m as well as in dB relative to the standardized reference of 400mA/m. Following the AFILS IEC 60118 standard, the new Minilyzer supports: Level Quasi Peak, 10ms integration time Level RMS, (F)ast and (S)low integration time Frequency Sweeps THD+N Measurements 1/3rd Octave Spectral Analysis Oscilloscope mode The Minilyzer enables the quick, simple and precise optimization of Induction Loop Systems for hearing aids user.

STI-PA Speech Intelligibility Option The STI-PA analyzer option allows durable and reliable speech intelligibility measurement within 15 seconds (typical). Besides the single value STI or CIS test result, a detailed view of modulation indices and individual band level results is provided. The STI-PA analyzer includes amplitude weighting in accordance with the 2003 IEC 60268-16 standards release. Acquired measurements may be referenced to previously established background noise level spectra's with automatic recalculation of the STI values.
