Selective attention in a vocal abuse population.

Area of Science:

• Audiology
• Speech-Language Pathology
• Psychoacoustics

Background:

• Vocal abuse can impact vocal fold health and voice production.
• Auditory processing in noise is crucial for effective communication.
• The relationship between vocal misuse and auditory perception in noise is not well understood.

Purpose of the Study:

• To compare the speech discrimination abilities in noise between female vocal abusers and non-abusers.
• To investigate the effect of different noise types on auditory discrimination.
• To explore potential links between vocal misuse and impaired listening skills.

Main Methods:

• Utilized the Goldman-Fristoe-Woodcock Test of Selective Attention.
• Compared 25 female vocal abusers with 25 female controls.
• Analyzed performance across three distinct background noise conditions: fan, cafeteria, and male speaker.

Main Results:

• The vocal abuse group demonstrated significantly poorer speech discrimination in noise compared to the control group.
• Both groups showed significant differences in discrimination between multi-talker (fan, cafeteria) and single-talker (male speaker) noise conditions.
• Fan and cafeteria noise presented greater challenges for speech discrimination than male speaker noise for both groups.

Conclusions:

• Female vocal abusers have impaired speech discrimination abilities in noisy environments.
• Auditory attention deficits may be associated with vocal misuse.
• Further research is warranted to explore the interplay between vocal behaviors and auditory processing in noise.
