Zusammenfassung:	A method for monitoring at least one journal bearing for a shaft in respect to at least one acoustic event is provided. The at least one journal bearing is coupled with a gearbox, whereina time dependent solid borne sound signal is detected by at least one solid borne sound signal sensor,the output signal of the at least one solid borne sound signal sensor is transmitted to a signal pre-processing device,frequency components of the solid borne sound signal with of more than 250 kHz are amplified in the signal pre-processing device and/orwith a frequency of less than 50 kHz are attenuated in the signal pre-processing device, andthe output signal of the signal pre-processing device is wirelessly transmitted via an antenna device to a signal evaluation device for the detection and/or location of the at least one acoustic event.
