A Thermal Transducing Microphone

چکیده
(6) If we now assign T0 to be the undisturbed air temperature of the surroundings, p as the small perturbation in pressure due to an acoustic wave and P0 as the ambient pressure we can derive the change in temperature occurring with a passing acoustic wave. ∆T is very small and is approximately ±0.23C with a very high sound level of 140 dB(SPL), ambient temperature of 20C, and an ambient pressure of 101.3 kPa.

A MEMS Capacitive Microphone Modelling for Integrated Circuits
In this paper, a model for MEMS capacitive microphone is presented for integrated circuits. The microphone has a diaphragm thickness of 1 μm, 0.5 × 0.5 mm2 dimension, and an air gap of 1.0 μm. Using the analytical and simulation results, the important features of MEMS capacitive microphone such as pull-in voltage and sensitivity are obtained 3.8v and 6.916 mV/Pa, respectively while there is no...
متن کاملFabrication and Characterization of a New MEMS Capacitive Microphone using Perforated Diaphragm
In this paper, a novel single-chip MEMS capacitive microphone is presented. The novelties of this method relies on the moveable aluminum (Al) diaphragm positioned over the backplate electrode, where the diaphragm includes a plurality of holes to allow the air in the gap between the electrode and diaphragm to escape and thus reduce acoustical damping in the microphone. Spin-on-glass (SOG) was us...

متن کاملRoom Impulse Response Variation Due to Thermal Fluctuation and Its Impact on Acoustic Echo Cancellation
In the field of acoustic echo cancellation, it is well known that the amount of cancellation attainable in real-world systems is limited. Euphemistically this limitation has been referred to in the acoustic echo cancellation community as the “20 dB rule” [1]. This rule reflects the observation that, typically, one can obtain only about 20 to 30 dB of acoustic echo cancellation in actual physica...
متن کاملEffect of thermal stresses on stability and frequency response of a capacitive microphone
This article deals with effects of thermal stresses on stability and frequency response of a fully clamped circular microplate, which acts as the diaphragm of a capacitive MEMS microphone. Static and dynamic pull-in phenomena limit the stable regions of a capacitive MEMS microphone. The results show that the non-dimensional static pull-in voltage of the studied case is about 5.23 (38.6 V). On t...
