while the structure of the broadband surface like absorber shown in fig1 is obviously particularly suitable for experimental purposes or for special production runs the embodiment shown in fig2 is suitable especially for series production when the surface like absorber in accordance with the invention is designed as yard ware for diy enthusiasts and tradesmen it is also possible to use a perforated plate sheet provided uniformly or at random with through openings and for it to be applied and joined to the underlying structure in a more or less random manner in a continuous production process this makes it possible to achieve good distribution of the resonance absorption while also achieving good to average absorption performance a broadband surface like absorber of this kind especially one produced by a continuous process is distinguished by a broad varied range of applications and the ability to be cut to size in areas of application where higher requirements apply both to the absorption performance and the spectral distribution of the absorption characteristics on the other hand for example to allow acoustic styling of noises within passenger cells of motor vehicles very careful structural definition of the absorption characteristics of the surface like absorber is required for applications on which higher requirements.
