Note (General): Cylindrical inlet noise suppressors for a high-bypass-ratio turbofan engine (FJR710/ 10 ) were tested. Perceived noise level attenuations obtained due to the suppressors were 10 PNdB for simulated approach conditions. Sound power attenuation spectra obtained by an insertion loss technique using far-field measurements also showed a maximum peak attenuation of 10 dB. Degradations of aerodynamic performance caused by the inlet noise suppres- sors were smaller than the experimental errors.
