Vocal and auditory symptoms and self-perception of voice and hearing in voice actors.
Heloísa Soares Povreslo, Ana Carolina Constantini
PMID 41370522WHAT IT FOUND
Most voice actors reported hearing issues, but few screened positive for voice disorders.
Throat clearing was the only symptom linked to both hearing loss and voice disorder risk. Energy drink use correlated with vocal strain and poor hearing perception.
Key findings
0156.4% of participants reported self-perceived hearing loss, while only 12.7% screened positive for voice disorder.
02Throat clearing was the only vocal symptom significantly associated with both suspected voice disorder and self-reported hearing loss.
03Energy drink consumption was associated with multiple vocal symptoms, including hoarseness and strained speech, as well as poor self-assessment of hearing.

What it does not show
The study relied entirely on self-perception; no objective audiological or acoustic measures were taken to confirm hearing loss or voice disorders. The sample was small (55 participants) and recruited via convenience sampling, limiting generalizability. The instruments were not originally validated specifically for voice actors, requiring adaptation for the actor's questionnaire. The cross-sectional design cannot determine causality between habits (like energy drink use) and symptoms.
Declared interests
The study was funded by FAPESP (2022/09502-8). The authors declared no other conflicts of interest.
The easy way to misread this
Do not assume that self-reported hearing loss indicates clinical hearing impairment, as the study used only perception questionnaires without objective audiological testing.
