A novel sound-based belt condition monitoring

2018-10-1  During the grinding process, sound signals are collected by an omnidirectional capacitance microphone (BSWA MP201). The frequency response range is from 6.3 Hz to 20 kHz, the open circuit sensitivity is 50 mV/Pa, and the dynamic range is from 17 to 146 dBA. The microphone is located laterally at a distance of 50 cm from the grinding surface.

Identifying grinding mill dynamics using acoustic ...

2020-6-30  Acoustic measurements have been conducted using a microphone array located in the front of the mill, at 1.36 m from it (Fig. 3 (a)). The array is composed of 64 1/4” GRAS 40 pH phase matched microphones (frequency range from 50 Hz to 10 kHz). Those microphones are mounted on a 2 m by 2 m perforated steel grid using plastic cable glands.

Methods of noise reduction

3 Reducing the source impedance (if possible) gives two benefits: Reduction in thermal noise voltage Reduction in capacitive interference coupling (see later) Example: Using 20 kHz bandwidth, a 1 MΩ sample at room temperature generates thermal noise of 20 µV. Reducing the resistance to 10 kΩ would reduce it to 2 µV.
