This paper describes the design, construction and perJormance of a test Jacility Jor transmission loss measurement. The receiving portion of the jacility consists oJ a 118 m 3 reverberation room, while the source room is a 1.0 m 3 pit with high sound insulation. The partition being measured makes up

This paper describes the design, construction and performance evaluation of a small test facility for transmission loss measurement. The low-cost.test facility--in the form of a twin pentagonal parallelepiped--is made of laminates of masonite, fibreglass, and plywood and is particularly adaptable fo
The paper is a general introduction #~to possible ways in which the sound insulation of facades could be measured. Examined are direction of measurement, noise source, sound pressure levels measurements and calculation of sound insulation.
## Abstract The design of a cavity resonator implies to solve the Maxwell equations inside that cavity, respecting the boundary conditions. As a consequence, the resonance frequencies appear as conditions in the solutions of the differential equation involved. The measurement of the complex permitt
