Abstract
A Hearing apparatuses and a hearing apparatus chip are provided. A hearing apparatus chip for processing a signal of a hearing apparatus includes a signal-processing component and a first ground wire connected to a first terminal of the component. The signal processing component includes a second ground wire galvanically separated from the first ground wire on the chip and is connected to a second terminal of the component by way of a capacitor, in order to conduct interference signals as a result of electromagnetic couplings. In particular, the sensitive ground of a preamplifier is not then interfered with by leakage currents.
