Abstract: An explosion-proof housing having external walls, which enclose a housing interior so as to be proof against ignition penetration relative to an atmosphere at risk of explosion. At least one insert is arranged in at least one outer wall. The insert facilitates a gas flow between the housing interior and an environment around the housing. The at least one insert is configured in such a way that a gas flow having a sufficient mass flow or volumetric flow rate is permitted, but a flow connection which is proof against ignition penetration is produced. Attached to the outer wall having the at least one insert is a guiding means which together with the relevant outer wall delimits a flow channel. The flow channel defines a main flow direction of a main gas flow through the flow channel substantially parallel to the directly adjoining outer wall. In this way, the gas exchange between the environment and the housing interior can be improved and facilities arranged in the housing interior can be cooled.

Abstract: A hearing device that can be produced particularly efficiently contains an antenna arrangement for wireless data transmission, in particular by magnetic induction. The antenna arrangement contains an antenna core made from a polymer matrix material into which a soft magnetic filler is embedded. A soft magnetic filler designates a filler made from a ferromagnetic material, i.e. from a material that can be easily magnetized in a magnetic field but does not itself form a magnetic field.
