Wide Band Noise

Twenty subjects with normal hearing and 20 subjects with sensori-neural hearing loss were examined relative to the effects of wide- and narrow-band white noise delivered by bone conduction at the forehead; differences between thresholds with interrupted- and continuous-tone presentation under the conditions of quiet, wide-band noise, narrow-band noise; the difference between threshold shifts at 1 000 and 2 000 cps when the SAL masking technique is used; and differences between SAL and conventional bone-conduction thresholds at 1 000 or 2 000 cps. Narrow-band noise produced less shift than wide-band noise under all conditions Differences between interrupted- and continuous-tone presentation yielded better thresholds. Shifts at 1 000 cps and 2 000 cps were significantly different, with the shift at 1 000 cps being greater.

Wide Band Noise

The study of short time scale phenomena of astronomical interest is often handicapped by the presence of wide band noise. In particular, in the study of the optical variability of stars, such noise arises from atmospheric scintillation, extinction variations, sky radiance variations and photon statistics. For example if in order to resolve rapid stellar variability we reduce the length (T) of the time intervals over which a photometric record is integrated and sampled, we find that the fractional noise fluctuations increase, eventually obscuring any intrinsic variability.
