About this study

Official title: Effects of Personal Protective Equipment on Speech Acoustics

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.

Read the detailed description

It was planned as a cross-sectional study enrolled 18 healthy male and female participants. After the informed consent, participants were asked to pronounce a [ɑː] vowel for at least 3 seconds for voice quality estimation. Afterward, all Turkish vowels were produced for a minimum of 200 ms. Finally, three Turkish fricative consonants ([f], [s], [ʃ]) were produced in consonant/vowel/consonant format and in different vowel contexts within a carrier sentence. Recordings were repeated for the following conditions: no PPE, surgical-mask, N99-mask, face shield, surgical-mask+faceshield, and N99+faceshield. All recordings were analyzed with proper statistical methods.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: 1 months

Questions about this trial

What is this clinical trial studying?

An observational study of Speech Disorders and Voice Disorders, run by Istanbul Medeniyet University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 May 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The change on voice acoustics due to different personal protective equipments use (time frame: 1 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05369663, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 May 2022.
