Narrow band noise audiometry: the effect of filter slope.
Children with sharply sloping audiometric configurations were examined audiometrically using pure tones and narrow bands of noise with equivalent bandwidths but varying in filter slope. Thresholds were established at the octave frequencies from 500 to 5000 Hz. The results indicated more sensitive thresholds for narrow bands of noise with threshold sensitivity improving progressively as filter slope decreased. Clinical implications are discussed.
