which move air particles to produce pressure waves. While dynamic drivers may cause distortion at high volumes, they are versatile, cost-effective, and reproduce bass frequencies very well.

The inter-connected resistors in the measuring bridge react to the distortion, engendering a piezoresistive ... For example, piezoelectric sensors can resist high temperatures and highly dynamic ...

The current version is a 2.4 meter long tube with a 5 cm inside diameter filled with a gas. At one end, the pressure is raised to about six atmospheres and held in check by a diaphragm that can be ...

The American Architectural Manufacturers Association (AAMA) recently released an updated document to provide a standard water penetration test method when using dynamic pressure. AAMA 501.1-17, the ...
