Informacja

The Type 1556-B Impact-Noise Analyzer (Figure l)is an amplifier-voltmeter system designed to measure peak value, maximum instantaneous level, and time duration of impact sound or vibration. By means of an electrical storage system in the instrument, all three characteristics of a single impact can be measured with only one indicating meter. The Impact- Noise Analyzer is usually used to measure the output of a Type 1551 Sound-Level Meter, a Type 1550-A Octave-Band Noise Analyzer, a Type 1553-A or 761-A Vibration Meter, or a magnetic tape recorder.
