Brief Summary

Severe acute respiratory syndrome coronavirus-2 transmits through droplets; thus, oral, nasal, and conjunctival mucosas are related to contamination, and wearing personal protective equipment (PPE) is strongly suggested. Several communication problems between the patient and healthcare workers related to PPE use are reported. In this study, investigators aimed to investigate changes in the acoustic parameters of speech sounds when different PPE are used.

Outcome Measures

Primary Outcomes (1)

• The change on voice acoustics due to different personal protective equipments use

  speech material for six different conditions: no PPE,surgical mask,N99 mask,face shield,surgical mask+ face shield, N99+face shield were recorded with a microphone.Recordings were performed in a random order. Obtained speech records were segmented according to the speech material and saved. Each of the segmented files was analyzed using Praat software and related scripts. The voice quality parameters were estimated on sustained \[ɑː\] vowels via Praat software (Praat is an open source software which enables voice acoustics analysis). Mean values of the different formant frequencies and formant bandwidth frequency values at midpoints of the analyzed segments of the vowels were measured. Spectral moments of the consonants were measured. The formant and spectral moment were measured using Praat scripts. All outcome measurements are in Hertz (Hz), so all measurements are held in primary outcome 1 measure section.
