English to Polish Tech/Engineering Other akustyka

Proszę o pomoc w tłumaczeniu tego terminu na j.polski. Tekst dotyczy akustyki. Po przejrzeniu kilku stron internetowych proponuję:
dyfuzor o losowej głębokości szczelin.
Kontekst:
Figure 4 demonstrates how the parametric acoustic diffuser tool can be used. Three types of diffuser panels are shown here: a fractal triangular pyramid, a random well-depth diffuser, and a fractal random well-depth diffuser. Triangles and pyramids can provide good diffusion and are often used in arrays. The scattering performance of the triangle depends on its side angle. An angle of 40 degrees was determined to be appropriate and to provide a good scattering of sound. The size of the triangular pyramids varies, and resultantly, this will scatter both the low and high frequency sounds differently. The layout and number of the triangular pyramids is determined by another parameter, the level of recursion. The second and third types of diffuser panels are based on the geometry of the Schroeder diffuser. They both have constant well width and random well depth. In the third option, the triangular panel is broken up into seven triangles along each side. Each of these triangles is then broken up again into seven triangles. This fractal technique allows the geometry to diffuse multiple frequency ranges.
