Environmental Noise Impact on aging hearing health and Sensorineural Speech
Processing

his presentation outlines hearing health damage and
sensorineural speech processing deficits in aging
populations caused by environmental noise exceeding
public health limits internationally. Irreversible sensory
(cochlear) and neural (auditory nerve) damage includes
hidden hearing loss, tinnitus, speech-to-noise ratio loss,
noise-induced hearing impairment, and accelerated
age-related hearing loss (presbycusis). Sensorineural
speech processing abilities differ greatly between late-
onset sensory presbycusis in people with no hazardous
exposure and early-onset neural presbycusis in people
with a history of high environmental noise exposure.
Widespread untreated hearing impairment increases risk
of cognitive decline and dementia. Environmental noise
levels causing speech interference impact vulnerable
populations including people with aging hearing health,
sensorineural speech processing deficits, and/or cognitive
declines. Quieter noise levels meeting public health limits
are urgently needed to protect hearing health and improve
access in public spaces for aging populations with quiet
communication needs.
