| Résumé | A brief description of the fan noise research test cell of the Engine Laboratory is given. Acoustic measurements inside the treated area of the cell showed satisfactory performance of the test area for fan noise research. Noticeable deviations from the inverse square law variations were observed especially at low frequencies near the inlet splitters and flow straighteners, and near the crane rail surface on the ceiling; these surfaces are not adequately treated. The agreement of the measured sound pressure levels with the inverse square law variation was excellent across the width of the cell. |
