Since there are some connection between the acoustic mode and the combustion instability,it is necessary to analyze acoustic modal of the aero-engine annular chamber flame tubes.

And there are some connections between the acoustic mode and the combustion instability.

A measuring method of acoustic modality of a car cavity is put forward to acquire its modal frequencies and modal shapes using LMS Test_lab software after gathering and analyzing test data of a real car.

This topic introduces the acoustic modality of car cavity,presents a kind of testing method to acquire the modal frequency and compares the test result with the result of Finite Element Analysis (FEA).

The acoustic modality of the enclosed cylindrical volute casing with asound-soft boundary and the mathematical modals at a higher order acoustic modal frequencyfor the volute casing of a centrifugal fan with a practical.

Acoustic modes of the combustion chamber were calculated with FEM software ANSYS when the length and number of baffles change,and the influences of the changes on the acoustic modes are compared.

Analysis is done to compare the results of acoustic model analysis with the excitation frequency characteristics of both inside and outside of the car,which provides the evidence for the cab noise prediction and the acoustic characteristic i.

Acoustic Modeling for Continuous Speech Recognition;

Researching of the Mongolian Acoustic Model Based on Speech Recognition;

A microstructure based acoustic model is introduced,which can be used to optimize the microstructure of cellular materials and thus to obtain their optimal acoustic property.

Small data set-based acoustic modeling for dialectal Chinese speech recognition;

In this paper, the techniques of acoustic modeling and parameter tying strategy are thoroughly studied.

This paper first introduces the background and history of the research on current broadcast news transcription systems; then describes the key technology of mandarin broadcast news transcription systems in details, such as acoustic modeling and adaptation technology.
