This paper presents an engineering approach for real-time ECG signal processing on a mobile phone with remote transmission to a medical center. The method uses an IIR low-pass filter and Hilbert transform to support R-peak detection and arrhythmia alerting. Reported algorithm performance includes 96.97% sensitivity…

This study evaluated whether the NAL-NL1 hearing-aid fitting formula is appropriate for hearing-impaired mobile communication, comparing it with a modified fitting formula. Speech materials were low-pass filtered at 8 kHz and presented through a mobile phone for word-recognition testing in quiet and noisy conditions.…
