This tutorial demonstrates a full electro-vibroacoustic analysis of a conceptual electrostatic speaker driver, composed of thin conducting plastic diaphragm residing between two perforated metal sheets called grids or stators. When an audio signal is applied to the grids (out of phase), ... 詳細を見る
This model studies a small orifice located in a duct. The transmission and reflection coefficients of the system are computed in the presence of a bias flow using the linearized Navier-Stokes equations. For certain frequencies the transmission coefficient shows amplification (T>1). This ... 詳細を見る
This small tutorial model studies energy conservation in a small conceptual test setup. The model has an inlet and outlet (modeled using ports) and a Helmholtz resonator with a very narrow neck. The acoustics in the narrow neck are modeled with Thermoviscous Acoustic for a detailed ... 詳細を見る
In microfluidic devices, it is a challenge to mix different fluids. One method is to use acoustic streaming to create a flow which enhances the mixing of two fluids. In this model, the vibrations of PDMS structures in a channel induces fast acoustic streaming used for mixing a diluted ... 詳細を見る
This tutorial computes the transfer matrix of a tube and coupler measurement test setup. This type of setup is used for standardized testing, for example, for miniature loudspeakers or hearing aids. The Port boundary condition in Pressure Acoustics, Frequency Domain is used together ... 詳細を見る
This tutorial shows how to model car cabin acoustics using a low frequency FEM solution concatenated with a high frequency ray solution. The source is a tweeter located in the dashboard corner, which is modeled as a lumped loudspeaker coupled to an electric circuit. To accurately include ... 詳細を見る
In acoustofluidics, acoustics is used to manipulate particles and fluids in microfluidic devices. This model demonstrates the phenomena of the inhomogeneous acoustic body force and how it can move a fluid with an inhomogeneous density due to a solute. The model is of a 2D cross section ... 詳細を見る
This model analyzes the scattering of a plane propagating modulated Gaussian pulse off a submarine hull. The scattered field and the spatial response are also determined. The model uses the Pressure Acoustics, Time Explicit interface to model this large acoustic model in the time domain. ... 詳細を見る
In applications where pressure waves and elastic waves propagate in porous materials filled with air both thermal and viscous losses are important. This is typically the case in insulation materials for room acoustics or lining materials in car cabins. Another example is porous materials ... 詳細を見る
In this model, the acoustics of the Small Hall in the Konzerthaus Berlin is simulated with Pressure Acoustics, Time Explicit. This method can take advantage of running on GPUs. A study of the room is performed in the low frequency range. The room acoustic parameters are derived from the ... 詳細を見る
