Relationships Between Autistic Trait Dimensions and Speech Understanding, Affective Sound Intolerance, and Self-Reported Hearing Difficulties

Decreased sound tolerance (DST) is a disabling transdiagnostic phenomenon with high clinical relevance in autism. Neurodevelopmental DST is often studied as part of a general multisensory construct that includes both hyper- and hyposensitivity. Therefore, knowledge about the potential relevance of individual differences in the auditory modality is lacking....

Discussion

Signed responses from readers of the wire.

✦ Clinical Takeaway ✦

Audiologists evaluating adults with autistic traits should consider assessing for sound intolerance (such as misophonia or hyperacusis) and self-reported hearing difficulty separately from standard audiometric thresholds, as different trait dimensions map onto distinct hearing-related challenges.

✦ Why It Matters ✦

Understanding how specific autistic trait dimensions relate to different hearing difficulties could improve individualised audiological assessment and rehabilitation planning for autistic adults and those with subclinical autistic traits.

✦ Key Points ✦

01Different autistic trait dimensions were associated with distinct hearing-related difficulties in adults.
02Affective sound intolerance (emotional distress from sounds) was significantly linked to certain autistic traits.
03Speech understanding difficulties showed a separate pattern of association from sound intolerance.
04Self-reported hearing difficulties did not fully align with objective hearing measures.
05Findings published in Autism in Adulthood, a peer-reviewed journal.

✦ Claims & Evidence ✦

Autistic trait dimensions are differentially associated with speech understanding, affective sound intolerance, and self-reported hearing difficulties in adults.

Self-reported hearing difficulties do not fully capture the range of hearing-related challenges experienced by adults with autistic traits.

Impaired speech-in-noise perception in individuals with a history of hearing symptoms after noise exposure

Audiologists should consider supplementing standard audiograms with speech-in-noise testing for patients reporting noise-exposure symptoms, as normal thresholds alone may miss clinically meaningful hearing dysfunction consistent with cochlear synaptopathy (hidden hearing loss).
