All
Inclusion criteria
Inclusion criteria: All relevant surgical procedures and associated post-anesthesia care unit (PACU) stays during the two-month study period were included. Cases (procedures and PACU stays), not individuals, served as the unit of observation. No specific inclusion criteria were defined, as the evaluation was conducted under real-world conditions without altering clinical workflows.
Exclusion criteria
Exclusion criteria: No exclusion criteria were defined, as the study was conducted under real-world conditions and all relevant cases within the study period were considered.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Change in measured acoustic parameters (e.g., sound pressure levels, psychoacoustic metrics) associated with the use of a visual noise display (SoundEar®3) in the operating room, emergency room and post-anesthesia care unit (PACU). | — |
Secondary
| Measure | Time frame |
|---|---|
| Change in clinically observed environmental factors, documented through structured observation (e.g., number and type of noise sources, interruptions during patient handovers, observed errors). | — |
