Experimental study on sound transmission in condenser
Even though there are lots of work studying acoustic resonance in tube bundles, the sound transmission rules barely got researchers attention. And most papers published assume that there is no interaction between the acoustic and structure modes. This paper tries to realize how sound source affects the acoustic transmission and whether the acoustic resonance could couple with the structure. A s...
متن کاملLow-Frequency Digital Phase Meter
A microcomputer-controlled measuring instrument for phase angle measurement in low frequency range is described. It is based on the digital measurement of the time shift between input signals. To avoid the necessity of calculation of the measured phase shift, measurement of the time shift is repeated during a constant time interval to get the average value of the phase shift independent on the ...
متن کاملLow Cost Digital Vibration Meter
This report describes the development of a low cost, digital Micro Electro Mechanical System (MEMS) vibration meter that reports an approximation to the RMS acceleration of the vibration to which the vibration meter is subjected. The major mechanical element of this vibration meter is a cantilever beam, which is on the order of 500 µm in length, with a piezoresistor deposited at its base. Vibra...
متن کاملEN 253: Matlab Exercise #3 Design of a Sound Level Meter
The goal of this Matlab exercise is to design an A-weighted sound level meter. Although previous years have utilized multirate filtering to reduce the computational overhead, this write-up will focus on a more direct implementation using the Fast Fourier Transform (FFT). Using the Data Acquisition Toolbox in Matlab, I have implemented a basic A-weighted sound level meter. This implementation al...
متن کاملVersatile optical microscopy using a reconfigurable hemispherical digital condenser.
We present a computer-controlled hemispherical digital condenser and demonstrate that a single device can be used to implement a variety of both well established and novel optical microscopy techniques. We verified the condenser capabilities by imaging fabricated periodic patterned structures and biological samples.
