Abstrakt v dalším jazyce:	This paper is oriented in the area of analysis of acoustic noise obtained from service of power engineering devices with very strong electromagnetic field. In this case not only operator but also measurement devices need protection. For this purpose optical insulated amplifier with frequency range up to 2 MHz was developed. We analyse acoustic signal from acoustic sensor in audible band from 1 kHz to 20 kHz. The acoustic signal transmitted from object is unique for specific conditions. Exploitation of audible band for PD phenomenon detection is difficult in outdoor bias level but with appropriate filtering it is possibile this disadvantage eliminate. Advantage of this method consist in simple results prepare.
