Description

Дл  приема акустических колебаний примен ют линейный микрюфон, который располагают; вдоль загнутых кокчиков упругих проволочек ( на фигурах не показано).To receive acoustic vibrations, a linear micruffle is used, which is positioned; along bent cocci of elastic wires (not shown in the figures).

Стабил зацд  уровн  возбуждаемых колебаний достигаетс  всЛедстви,е уменьшени  до минимума трени  упругих элементов о контролируемую поверхность . Возбуждение колебаний при этом происхсздит путем ударов по контролируемой поверхности. При этом исключаетс  вли ние шероховатости и направление облицовки (шпона) на уровень возбуждаемых колебаний.Stabilization of the level of the excited oscillations is achieved by reducing the friction of elastic elements against a controlled surface to a minimum. The excitation of oscillations in this case occurs by striking the controlled surface. This eliminates the influence of roughness and the direction of the cladding (veneer) on the level of excited vibrations.
