Identifying grinding mill dynamics using acoustic ...

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.

Close Miking in Recording: Why, When, & How? | LedgerNote

Close miking is a crucial technique for a majority of recording situations. Playing live in a bar, on stage singing or giving a speech, and even in the perfect acoustic environment of a world-class studio, close miking has it's place as one of the most effective means of faithfully capturing a sound source or instrument while keeping the signal as dry as possible.

Ventilation Diagnosis of Angle Grinder Using Thermal Imaging

The paper presents an analysis and classification method to evaluate the working condition of angle grinders by means of infrared (IR) thermography and IR image processing. An innovative method called BCAoMID-F (Binarized Common Areas of Maximum Image Differences—Fusion) is proposed in this paper. This method is used to extract features of thermal images of three angle grinders. The …

Lo-fi recording techniques and discussion (black metal ...

To elaborate, recording in lo-fi could be anything from using 4-track tape recorders to minimalist methods of capturing a project in a not-studio-space. This applies to the black metall'ers mostly but lots of grind, death, and thrash seems to fall into this category every once in awhile every so often.

Development of an intelligent grinding system for ...

The intelligent grinding system included several vibration, temperature, and acoustic emission sensors and a microphone to monitor the dynamic status of machine during the grinding process and help to quality control. The wear of the diamond grinding wheel could be predicted immediately by analyzing the collected data in this system.

Prediction of Tool Forces in Manual Grinding Using ...

Tool forces are a decisive parameter for manual grinding with hand-held power tools, which can be used to determine the productivity, quality of the work result, vibration exposition, and tool lifetime. One approach to tool force determination is the prediction of tool forces via measured operating parameters of a hand-held power tool. The problem is that the accuracy of tool force prediction ...

Theory | IMCE - Your partner in the Impulse Excitation ...

The Poisson's ratio is a measure in which a material tends to expand in directions perpendicular to the direction of compression. After measuring the Young's modulus and the shear modulus, the dedicated impulse excitation technique software determines the Poisson's ratio using Hooke's law which can only be applied to isotropic materials according to the different standards (ASTM E1876-15 ...

Acoustic Ground Microphone Technology

Limitations of Acoustic Ground Microphone Technology. Background noise can interfere with leak sounds. Pressure must be high enough for the leak to produce a sound. Maximum depth for pinpointing is 5-8 feet for 1-3 gallon per minute (GPM) leak. Pinpointing over soft soil or grass cover is more difficult.
