Research has reported negative patient outcomes, for example, decreased satisfaction, sleep disturbance, and higher incidence of rehospitalization in patients staying in areas with higher noise levels.Įnvironment of care nursing unit design patient room design patient-centered care post-occupancy evaluation veterans. Our findings, considered independently and collectively, showed that facilities in this study exceeded the WHO-recommended sound levels for patient rooms of 35 dB(A) during daytime and 30 dB(A) during nighttime. Average nighttime measurements for patient rooms and nurses stations were Site A-62 dB(A)/55 dB(A), Site B-48 dB(A)/55 dB(A), and Site C-42 dB(A)/60 dB(A). Average daytime measurements for patient rooms and their corresponding nurses stations were as follows: Site A-63 dB(A)/56 dB(A), Site B-52 dB(A)/55 dB(A), and Site C-42 dB(A)/59 dB(A). Averages as well as highest and lowest readings are reported for both daytime (8 a.m.-10 p.m.) and nighttime (10 p.m.-8 a.m.) for each facility.Īll three sites are considered urban and are classified with the highest complexity level (1a). These sound levels were averaged for each hour for reporting purposes. An Amprobe SM-20A Sound Level Meter was placed for a 24-hr period and recorded decibel levels every 8 min. Sound assessments were conducted at three healthcare facilities in both patient rooms and nursing stations, and we include information on facility characteristics. The ISO Standard 80000-3:2006 sets out the following quantities. One decibel 1/10th of one bel (hence the name ‘Deci’), named in honour of Alexander Graham Bell. Assessing post-occupancy sound levels enables hospital administrators and healthcare workers to identify whether interventions to improve sound levels are needed. The first use of the decibel scale was for the measurement of power in the telephony of the early 20th century in the Bell System in the United States. The World Health Organization (WHO) recommends sound levels of 35 dB(A) during the day and 30 dB(A) during the night however, many hospitals exceed these recommended levels. Discover the magic of the Decibel Scale, the key to measuring sound intensity. To conduct an assessment of sound, dB(A) levels, in two areas of the hospital: patient rooms and nurse stations using sound meters (SMs).
