Melodic Sequence Analysis
For alarms that sound a melody, the MAA software determines the fundamental and harmonic frequency information of each pitch in the melodic sequence, then transposes the melody and compares it to the specific reserved alarm melody dictated by IEC 60601-1-8 (cardiac, artificial perfusion, ventilation, etc.). A table is generated which shows the measured frequency in Hertz and the note name, the required note, if the note is out of tune, and a pass/fail indication for each pulse in the sequence.
