Abstract. Appliances equipped with single-cylinder combustion engines generate noise which may have an adverse effect on human health. Lawnmowers are one of the most popular examples of appliances utilising a drive of this type. This paper presents the results of measurements of sound levels emitted by such mowers and received in the whereabouts of their users. The effect was analysed of a change in the technical condition of their drive on the sound level and a method was proposed to assess its impact on users. The basis of the method is the summation of selected 1/3 octave bands, in which the main energy of noise generated by mowers with single-cylinder combustion engines is radiated.
