Finite element modelling of surgical transducers has been performed and is described. Ultrasonic transducers vibrating at around 25 kHz are used in orthopaedic surgery to cut bone. The high acoustic impedance of the metal blades used in these devices couples energy more efficiently to ... 詳細を見る
Periodical architected structures comprising reticulated beams or trusses have proven capable of controlling wave propagation at different frequency scales. Moreover, recent progress in 3D printing techniques has paved the way to their actionable application in various fields, i.e., ... 詳細を見る
Duct silencers are used to reduce noise in Heating, Ventilation and Air Conditioning (HVAC) as well as noise from exhaust gas chimneys. For a duct silencer, an important trade-off has to be made between the achieved noise reduction and the pressure drop. Using an example model, we will ... 詳細を見る
A gearbox used in a vacuum cleaner robot is evaluated regarding noise and vibration in COMSOL Multiphysics®, using the Multibody Dynamics and the Acoustics Module. The real gearbox is powered by a DC motor and consists of four plastic helical gears forming a gear train and is used to ... 詳細を見る
COMSOL Multiphysics® has proven to be an invaluable “virtual laboratory” tool in assisting our development of a new generation of efficient analytical models describing the acoustics of highly porous fibre and foam materials. From the definition of the physical relations describing the ... 詳細を見る
Shape and Topology Optimization of Loudspeaker Drivers This paper illustrates the use of formal mathematical optimization techniques for engineering solutions focused towards loudspeaker drivers. Both shape and topology optimization techniques are applied, with the physics ranging ... 詳細を見る
Micro-Electro-Mechanical Devices such as acoustics sensors, finger print sensors, tunable capacitors etc. are widely used in commercial applications. The pressure sensors use membranes which deflect upon applied pressure load. The most important aspect of any pressure sensor is its ... 詳細を見る
Thermal ablation is a treatment option in oncology that can be used to target primary and metastatic cancers. In this approach, high temperature heating is administered at the target tumor site to induce coagulative necrosis of malignant cells. One minimally invasive method for ... 詳細を見る
Modern home audio products are starting to feature dedicated upward firing height channel speakers, which are a combination of unique physical speaker design and special signal processing, to reproduce audio as if the sound source is located in the ceiling. Due to slim form factor design ... 詳細を見る
Aerodynamic sound is generated by unsteady fluid motion and enhanced when the flow becomes turbulent. For example, drone is loud because the ambient air is stirred by their propeller to get lift and movement and the air becomes turbulent. Reduction of aerodynamic noise is an important ... 詳細を見る
