The frequency at which a sound wave incident upon a surface has a projected wavelength equal to the length of the bending wave excited in the surface material. The effect of this "trace matching" is a marked reduction in the sound transmission loss in the frequency region in which this occurs. The frequency is a function of the angle at which the sound impinges on the surface, the surface weight, and bending stiffness of the surface. 2, record 1, English, - coincidence%20frequency

Les pertes de transmission du son par les cloisons et les planchers dépendent également de la rigidité. Les courbes des pertes de transmission de son pour les matériaux rigides présentent des creux à certaines fréquences par rapport aux pertes calculées selon la loi de masse. Cet effet dit de coïncidence entraîne souvent un ITS plus faible. Les matériaux peu rigides comme les feuilles de plomb n'ont pas de creux de coïncidence. Les fréquences de coïncidence des différents matériaux se produisent dans diverses parties du spectre acoustique, parfois en dehors de la gamme normale utilisée en acoustique du bâtiment. 2, record 1, French, - fr%C3%A9quence%20de%20co%C3%AFncidence
