Abstract
The paper proposes and justifies a way to increase the security of speech information by attaching glass tubes (stiffeners) to a window fence. A method for estimating changes in the resonances of a window fence with fixed stiffeners is given. With the help of the developed laboratory installation, the study of window barriers without and with installed stiffeners was carried out, according to the layout patterns. Calculated indicators of changes in the maximum resonance of the window fencing with installed stiffeners. The schemes with the highest and lowest levels of attenuation of the total maximum resonance are determined, the effect of resonance shifting in frequency is shown with stiffening ribs set.
