摘要:
A reinforced concrete reverberation chamber has been constructed with diffusing cylinders of random size cast in the ceiling and walls. Energy loss in the empty chamber is low because the rigid, heavily enameled walls have a low absorption coefficient and the attenuation loss in the air is moderate for such a small volume. Materials are tested in the frequency range from 250 cps to 12 kc using half‐octave noise bands.
