In the study, there are compared the results of noise level measurements for the spark-ignition unsupercharged engine and a supercharged biogas engine. The examination was conducted for three values of rotational speed for unloaded and loaded engines. It has been determined, that as far as engines operating without loading, the noise level does not depend on an engine furnishing with a supercharging system. For loaded engines, a higher level of noise was found as compared to an engine not equipped with a turbocompressor.
