La Galleria delle Applicazioni raccoglie un'ampia varietà di tutorial e di app dimostrative realizzati con COMSOL Multiphysics in diversi ambiti applicativi, inclusi quelli elettrico, meccanico, fluidico e chimico. E' possibile scaricare i file dei modelli e delle app demo pronti all'uso e le istruzioni step-by-step per costruirli, e utilizzarli come punto di partenza per le proprie simulazioni.

Lo strumento di Ricerca Rapida permette di trovare i modelli che si riferiscono alla propria area di interesse.

Si noti che molti degli esempi qui presentati sono accessibili anche tramite le Librerie delle Applicazioni incorporate nel software COMSOL Multiphysics® e disponibili dal menu File.

Headphone on an Artificial Ear

Headphones are closely coupled to the ear, and so it is not possible to measure their sensitivity in a classical acoustic free-field setup used for loudspeakers. The measurement requires the use of artificial heads and ears to accurately represent the usage conditions. This model shows ... Per saperne di più

Small Concert Hall Acoustics

Designing structures and open spaces with respect to sound quality is important for concert halls, outdoor environments, and even the rooms of a house. Simulating acoustics in the high-frequency limit, where the wavelength is smaller than the geometrical features, can be done with ray ... Per saperne di più

Acoustics of a Living Room

Prevent shaking windows and enhance the sound experience by careful positioning of the loudspeakers in your room. This tutorial analyzes the low frequency response of a living room to the woofer units of two loudspeakers, and solves for the eigenfrequencies of the room. The room geometry ... Per saperne di più

Eigenmodes of a Room

When designing a concert hall, it is extremely important to take the resonances into account. For a clear and neutral sound, the eigenfrequencies should be evenly spread through the registers. For the home stereo owner, who cannot actually change the shape of his living room, another ... Per saperne di più

Electrostatic Speaker Driver

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), ... Per saperne di più

Lumped Receiver with Full Vibroacoustic Coupling

When simulations are involved in the development of mobile devices, consumer electronics, hearing aids, or headsets, it is necessary to consider how the transducers interact with the rest of the system. Here, we show an analysis of the interaction between a vibration isolation mounting ... Per saperne di più

Generic 711 Coupler — An Occluded Ear-Canal Simulator

This is the model of an occluded ear canal simulator (a generic 711 coupler). Besides certain details the geometry corresponds to the Brüel & Kjær Ear Simulator Type 4157. The real life couplers are used for simulating the acoustics of a standardized human ear canal and can be used ... Per saperne di più

OW Microspeaker: Simulation and Correlation with Measurements

This model analyzes the electromagnetic, mechanical, and acoustical characteristics of the OWS-1943T-8CP (discontinued) speaker. Beside certain details, the geometry, material properties, and measurements are copyright by Ole Wolff. Starting from the geometry of the speaker, an ... Per saperne di più
