Upward spreading of masking, measured in terms of absolute masked threshold, is greater in hearing-impaired listeners than in listeners with normal hearing. The purpose of this study was to make further observations on upward-masked thresholds and speech recognition in noise in elderly listeners. Two age groups were used: One group consisted of listeners who were more …

Upward spread of masking is low-frequency sounds masking high-frequency sounds. Downward spread of masking occurs when low-frequency sounds are masked by an intense level of high-frequency sounds. Masking is more effective when the loud sound is a low-frequency sound and the soft sound is a high-frequency one, rather than the opposite.

Regardless of the degree of hearing loss, upward spread of masking is always a possibility but is not easily predicted from aided or unaided threshold measures. Of course, the only direct way to know if upward spread of masking is a problem for a given listener is to perform sufficiently sensitive speech perception measures under different frequency response conditions.
Suppression and the upward spread of masking
https://pubmed.ncbi.nlm.nih.gov/9857509/
In contrast, recent physiological studies have indicated that upward spread of masking in the auditory nerve is due to the increasing effect of suppression with increasing masker level. This study compares thresholds for signals between 2.4 and 5.6 kHz in simultaneous and nonsimultaneous masking for conditions in which the masker is either at or well below the …

Classical psychophysical models assume that masking is primarily due to the spread of masker excitation, and that the nonlinear upward spread of masking reflects a differential growth in excitation between the masker and the signal at the signal frequency. In contrast, recent physiological studies have indicated that upward spread of masking in the …

Upward spreading of masking, measured in terms of absolute masked threshold, is greater in hearing‐impaired listeners than in listeners with normal hearing. The purpose of this study was to make further observations on upward‐masked thresholds and speech recognition in noise in elderly listeners. Two age groups were used: One group consisted of listeners who …

Sensorineural Hearing Loss and Upward Spread of Masking. Pure-tone auditory thresholds were obtained in quiet and in three levels of masking noise for one normal-hearing group and five groups of subjects with different degrees of sensorineural loss. The masker was a low-pass noise, cut off at 250 Hz.
