Abstract
An acoustic absorber is made of a pot-shaped lower part with a pot bottom and side wall as well as an upper part having a horn. The horn projects into the bottom part and tapers in the direction of the pot bottom. Undesired noise is effectively reduced by the absorber. A relatively broadband, and at a given size, a relatively low-frequency absorption effect is achieved that is capable of protecting human hearing from injury or reducing the impact of noise such as on technical equipment and components.
