Primary Outcome Measures

Name	Time	Method
Main noise decibel	From enrollment to the end of observation at 1 week	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.

Secondary Outcome Measures

Name	Time	Method
Secondary noise decibel	From enrollment to the end of observation at 1 week	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.
Area of post anesthesia care unit	From enrollment to the end of observation at 1 week	Measure the area of the post anesthesia care unit using a tape measure, in square meters.
Number of beds of post anesthesia care unit	From enrollment to the end of observation at 1 week
Medical personnel allocation situation	From enrollment to the end of observation at 1 week	Number of anesthesiologists and nurses
Staying time in post anesthesia care unit of patients	From enrollment to the end of observation at 1 week
Number of patients with or without tracheal intubation retained	From enrollment to the end of observation at 1 week	Defined as patients whether retaining the endotracheal tube before entering the post anesthesia care unit
Daily working hours of medical staff	From enrollment to the end of observation at 1 week
Working years of medical staff	From enrollment to the end of observation at 1 week
Subjective perception of noise by medical personnel	From enrollment to the end of observation at 1 week	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.
The impact of noise on the work of medical personnel	From enrollment to the end of observation at 1 week	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.
The source of noise as perceived by the medical staff	From enrollment to the end of observation at 1 week	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.
Satisfaction of medical staff with the current noise situation	From enrollment to the end of observation at 1 week	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.
