What is being measured
The primary outcome is the main question the study is designed to answer.
Main noise decibel
The level of noise decibel in the post anesthesia care unit when the number of patients is between half and three-quarters of the total number of beds. Using noise vibration measuring instrument (AWA5688, Hangzhou Aihua Instrument Co., Ltd.) to measure the noise decibel.
Measured: From enrollment to the end of observation at 1 week
Secondary outcomes (12)
Secondary noise decibel
The level of noise decibel in the post anesthesia care unit when the number of patients is not between half and three-quarters of the total number of beds. Using noise vibration measuring instrument (AWA5688, Hangzhou Aihua Instrument Co., Ltd.) to measure the noise decibel.
Measured: From enrollment to the end of observation at 1 week
Area of post anesthesia care unit
Measure the area of the post anesthesia care unit using a tape measure, in square meters.
Measured: From enrollment to the end of observation at 1 week
Number of beds of post anesthesia care unit
Measured: From enrollment to the end of observation at 1 week

Measured: From enrollment to the end of observation at 1 week
Daily working hours of medical staff
Measured: From enrollment to the end of observation at 1 week
Working years of medical staff
Measured: From enrollment to the end of observation at 1 week
Subjective perception of noise by medical personnel
Using multiple-activity scale for hyperacusis (MASH) that is proposed by Dauman in 2005 to evaluate emotion. MASH categorizes the level of annoyance caused by noise into five levels: absent, mild, moderate, substantial, and severe. In our study, every individuals will be given a score of zero to four based on this five levels, higher scores mean a worse outcome.
Measured: From enrollment to the end of observation at 1 week
The impact of noise on the work of medical personnel
Based on our preliminary research findings, we have made a questionnaire titled "Working Conditions in Noisy Environments", which indicates that the impact of noise in the post anesthesia care unit on the work of medical personnel is usually as follows: no impact, failure to hear patient calls or needs in a timely manner, inability to identify alarms from specific medical equipment, need to speak loudly, and throat discomfort.
Measured: From enrollment to the end of observation at 1 week
The source of noise as perceived by the medical staff
Based on our preliminary research findings, we have made a questionnaire titled "Noise source in Post Anesthesia Care Unit", which includes monitor, sputum suction device, ventilator, conversation, mobile phone, printer, outdoor factors (such as the move of transfer beds.), and other.
Measured: From enrollment to the end of observation at 1 week
Satisfaction of medical staff with the current noise situation
Based on our preliminary research findings, we have made a questionnaire titled "Satisfaction with the Current Noise Situation in the Post Anesthesia Care Unit", which includes very satisfied, satisfied, general,dissatisfied, and very dissatisfied.
Measured: From enrollment to the end of observation at 1 week
