I.V.Vovk, A.A.Makarenkova Experimental study of interferences occurring at recording the respiratory noise by electronic sthetophonendoscopes |
Acoustic bulletin, Vol. 10 ¹ 4, (2007) |
| The study deals with experimental estimating of spectral levels of interferences occurring when listening human respiratory noise by electronic sthetophonendoscopes. By influence rate on quality of recording, the interferences of different types are subdivided in two categories: strong and weak ones. Recommendations, that allow lowering their role in the resulting signal, are brought forward. |
