The impact of face masks on the communication of adults with hearing loss during COVID-19 in a clinical setting.

ABSTRACT

OBJECTIVE: The aim of the study was to investigate the effect of surgical masks and face shields on speech intelligibility of adults with moderate to severe hearing loss. DESIGN: This study measured speech tracking scores in quiet for life speech in three different conditions without a mask, with a surgical mask and with a face shield. Acoustic effects of the masks and face shields on the speech signal were also investigated. Study sample The study sample consists of 42 patients with moderate to severe hearing loss, 23 cochlear implant users and 19 hearing aid users. RESULTS: A significant average difference in speech perception scores was found for the use of a surgical mask compared to the listening situation "without mask". The worse the speech understanding in quiet, the larger the impact of the surgical mask. For the worse performers even the face shield had a negative impact on speech perception. The sound distortion for the face shield compared to the surgical mask was greater. CONCLUSION: This study shows that even for speech perception in quiet, surgical face masks, and face shields to a lesser extent, have a negative effect for patients with moderate to severe hearing loss.
