| Abstract | ||
| Studying for sound and noise is of great importance nowadays. And since the internal combustion engines are main sources of noise pollution, this study established to investigate the relationship between the acoustic powers immersed from two different electric generators and the applied variable loads. The engines are of single cylinder four stroke air cooled gasoline type engaged with electric generator heads. The results show an agreement with other works on other types of engines (diesel engines), and it is found that used generators make noise much more than factory specifications and this noise lower with load increment, in contrary in brand new generators noise grow with load increment. Key words: acoustic power , noise attenuation , muffler | ||
